Player Outlook
Zac Gallen turned in another solid but not ace-level season. His career 26.6 percent strikeout rate is very good, but not elite. Last year, it was a career low of 25.1 percent. After two years of declining walk rates, Gallen's 8.7 percent clip was a smidge worse than average. Yielding only 13 homers in 148 frames kept Gallen's ERA in check, but if the 2025 baseball is livelier than the 2024 version, Gallen's ratios could suffer, unless he returns to a lower walk rate. Gallen's velocity was in sync with past seasons, so it's a matter of throwing more strikes. In 2023, 64.5 percent of his pitches were strikes, compared to only 61.9 percent last season. There was a time when Gallen fanned 28 percent of batters and was a back end SP1. He's now a solid SP3, with SP2 upside if he can throw more pitches in the zone.

  • Diamondbacks' Zac Gallen: Struggles with control vs. Orioles

    Rotowire
    Gallen (1-2) allowed five runs on seven hits and four walks while striking out two batters over 4.2 innings in a loss to Baltimore on Monday. Gallen's outing was a stark contrast to his 13-punchout, zero-walk win over the Yankees last Wednesday. Against the Orioles, the right-hander struggled mightily with his control, throwing only 50 of 96 pitches for strikes and issuing four free passes. Two of the four batters Gallen walked came around to score, and he failed to complete five frames for the second time in three starts. Despite Gallen's dominant victory last week against New York, his ERA stands at 5.28 on the season, which reflects how poor his other two outings have been. He'll try to rebound the next time he takes the mound, which is lined up to be Sunday versus Milwaukee.

  • Diamondbacks' Zac Gallen: Dominates Yankees with 13 punchouts

    Rotowire
    Gallen (1-1) earned the win over the Yankees on Wednesday, racking up 13 strikeouts without issuing a walk while allowing three hits over 6.2 scoreless innings. Gallen struggled in his first start of the season, yielding four runs over four innings against the Cubs. He bounced back in elite fashion Wednesday, registering 24 whiffs -- surpassing his previous career-high mark of 20 -- en route to 13 strikeouts, tying his career-best total. Gallen worked up to 101 pitches in the outing after throwing 83 on Opening Day. The right-hander will try to build upon Wednesday's fantastic performance in his next start, which lines up to come at home against Baltimore next week.

  • Diamondbacks' Zac Gallen: Allows four runs in opener

    Rotowire
    Gallen (0-1) took the loss Thursday against the Cubs after giving up four runs on four hits and four walks over four innings. He struck out four. Gallen finished spring training with a 2.89 ERA and 10:5 K:BB in 9.1 Cactus League innings, and his command was shaky again Thursday as he threw just 43 of 83 pitches for strikes. The right-hander will need to get on track quickly, as he's set for a matchup with the Yankees in his second start of the season next week.

  • Diamondbacks' Zac Gallen: Makes final spring start

    Rotowire
    Gallen allowed one run on five hits and two walks while striking out two over 4.1 innings in Thursday's spring start against the Athletics. Gallen made his final Cactus League start a few hours after he was tabbed for the Opening Day assignment by manager Torey Lovullo. The right-hander threw 73 pitches (43 strikes) and told Alex Weiner of Arizona Sports that he was more in sync during this outing than in previous starts. Next up for Gallen is Thursday's regular-season opener against the Cubs.

  • Diamondbacks' Zac Gallen: Named Opening Day starter

    Rotowire
    Gallen will start Opening Day, March 27 against the Cubs, Steve Gilbert of MLB.com reports. Many anticipated Corbin Burnes to make his Diamondbacks debut in the first game of the season, but the team will instead give the Opening Day start to Gallen for the third consecutive year. The 29-year-old has made three appearances in the Cactus League this spring, giving up two earned runs while striking out eight batters and walking three over five innings. While Gallen may never return to his 2022 form (2.54 ERA, 0.91 WHIP), he hasn't lost his strikeout stuff and should be able to comfortably reach double-digit wins with Arizona's high-scoring offense behind him.

  • Diamondbacks' Zac Gallen: Makes first spring appearance

    Rotowire
    Gallen allowed one run on one hit and struck out two over one inning in Monday's spring game against Cleveland. Gallen threw 15 pitches (nine for strikes), including a changeup that Gabriel Arias sent back over the fence in left-center field. The right-hander told Steve Gilbert of MLB.com that he felt better than his most recent live batting practice session, but the changeup that Arias hammered was "kind of flat." Gallen and Corbin Burnes are considered co-aces -- each has thrown one Cactus League inning -- and manager Torey Lovullo is still deciding which one will start Opening Day.

  • Diamondbacks' Zac Gallen: Strikes out 11 in 14th win

    Rotowire
    Gallen (14-6) picked up the win over the Giants on Wednesday, allowing one run on two hits and two walks over six innings while striking out 11. The only run charged to Gallen on the night came across in the second inning after he walked the leadoff man to open the frame before then surrendering an RBI double to Tyler Fitzgerald. The right-hander responded by retiring 14 of the next 15 batters he faced while also posting a season-high 11 strikeouts in the contest. Gallen generated 16 whiffs on the night and it marked the third time this season in which he's recorded double-digit strikeouts. He's now won his last five decisions (spanning seven starts) and carries a 2.67 ERA in September to go along with a 38:11 K:BB. On the downside, Gallen has also issued multiple free passes in nine of his last 10 outings.

  • Diamondbacks' Zac Gallen: Carried to win by offense

    Rotowire
    Gallen (13-6) picked up the win Friday, giving up four runs on seven hits -- including three home runs -- and a walk over five innings in a 7-4 victory over the Brewers. He struck out five. The righty blanked Milwaukee for four innings before falling apart in the fifth, blowing a 4-0 lead by serving up long balls to Joey Ortiz, William Contreras and Garrett Mitchell. Arizona struck back for three more runs in the top of the sixth, however, allowing Gallen to escape with the win. It marks Gallen's first time allowing multiple homers since April 26, and he's been both lucky and good down the stretch as the Diamondbacks push for a playoff spot, going 4-0 over his last six outings with a 3.38 ERA, 1.19 WHIP and 43:15 K:BB through 32 innings. He lines up to make his final start of the regular season at home next week against the Giants.

  • Diamondbacks' Zac Gallen: Another scoreless start

    Rotowire
    Gallen (12-6) earned the win over the Rangers on Tuesday, allowing two hits and two walks while striking out seven over five shutout innings. Gallen has kept a scoreless stat line in three of his last four outings, with the exception being a five-run outing against the Dodgers. Over that four-start span, Gallen has a 31:12 K:BB across 22 innings. The right-hander is now at a 3.55 ERA, 1.27 WHIP and 133:49 K:BB through 132 innings over 25 starts this season. He'll look to keep things on track in his next start, which is projected to be at Colorado.

  • Diamondbacks' Zac Gallen: Yields five runs in loss

    Rotowire
    Gallen allowed five runs on six hits and two walks while striking out seven over five innings in a no-decision versus the Dodgers on Friday. Gallen once again followed a strong start -- a six-inning scoreless outing versus the Red Sox last Saturday -- with a dud, though the Dodgers are a tough opponent for anyone. Over eight starts since the All-Star break, Gallen has allowed 19 runs across 44.1 innings, with 17 of those runs coming in just four of the starts. The right-hander is at a 3.87 ERA, 1.31 WHIP and 118:43 K:BB through 121 innings over 23 starts this year. He's never walked 50 batters in a season, but it appears inevitable he will this year as he's issued multiple walks in seven of his last eight starts. Gallen is projected to make his next start at San Francisco.

  • Diamondbacks' Zac Gallen: Removed due to cramps

    Rotowire
    Gallen was removed from his start in Saturday's 11-1 win over the Phillies due to general body cramps, but he doesn't expect to miss time, Jesse Friedman of GoPHNX.com reports. Fantasy managers can breathe a sigh of relief knowing that Gallen didn't sustain an injury Saturday and was merely experiencing cramping. Despite getting ample run support, the 28-year-old fell short of reaching the five frames he needed to qualify for the win, as he covered 4.1 innings and struck out three batters while yielding one run on five hits and two walks prior to departing. Gallen is tentatively scheduled to pitch during a three-game road series against the Rays next weekend.

  • Diamondbacks' Zac Gallen: Gives up five runs in no-decision

    Rotowire
    Gallen did not factor into the decision in a win over the Guardians on Monday, allowing five runs on eight hits and two walks over seven innings. He struck out four. Gallen snapped a streak of three straight starts with a win despite his team giving him plenty of run support on Monday. Despite throwing at least seven innings for just the second time this season, he just didn't have his best stuff and was constantly in trouble. The 29-year-old hasn't been as sharp as he would like recently, as he's allowed five or more runs in three of his last six outings.

  • Diamondbacks' Zac Gallen: Notches third straight victory

    Rotowire
    Gallen (9-5) earned the win over Washington on Wednesday, allowing one run on six hits and one walk while striking out six batters over six innings. Gallen gave up a run in the fourth inning but otherwise silenced the Nationals for his second straight quality start and third straight victory. Since giving up a season-high seven runs (six earned) over 3.2 frames against Toronto on July 14, Gallen has surrendered just four runs over his subsequent 17 innings. The right-hander's control had been shaky coming into Wednesday, however, as he had issued nine free passes across his previous two outings. He may have eased those concerns against Washington by issuing just one walk in the win.

  • Diamondbacks' Zac Gallen: Wild in win

    Rotowire
    Gallen (7-5) allowed three hits and six walks while striking out four over five shutout innings, earning the win Saturday over the Cubs. Gallen was unusually lacking in command and control -- this was the second time in five starts he's walked multiple batters, and it's the first time all year he's walked more batters than he's struck out. The Cubs were unable to punish his wildness, and the Diamondbacks' bullpen went on to yield just one hit over four scoreless innings to preserve a 3-0 lead. Gallen is now at a 3.64 ERA, 1.25 WHIP and 80:27 K:BB through 81.2 innings across 16 starts this year. The right-hander's next start is projected to be at home versus the Pirates.

  • Diamondbacks' Zac Gallen: Suffers first loss since return

    Rotowire
    Gallen (6-5) took the loss Tuesday against Atlanta, allowing five runs (four earned) on seven hits and a walk while striking out four over 5.1 innings. Gallen needed 53 pitches just to get through the first two innings, which is the most for him in a start this year. Atlanta pushed two runs across on him in the second, though one came off an error. Gallen then tossed three scoreless frames before coming back out for the sixth, and faltered there, allowing two men on before Adam Duvall crushed a curveball 441 feet to left to put Atlanta up 5-0 and end Gallen's night at 105 pitches. The home run was just the third Gallen's given up in his last seven starts (excluding his May 30 start when he exited the game after one batter). The 28-year-old owns a 3.33 ERA, 1.14 WHIP and 75:20 K:BB in 73 innings and lines up for one final start before the All-Star break against Toronto this weekend.

  • Diamondbacks' Zac Gallen: Triumphant in return

    Rotowire
    Gallen (6-4) allowed a hit and a walk while striking out seven over six shutout innings to earn the win over the Athletics on Saturday. Gallen returned from a hamstring injury that cost him nearly a month and took full advantage of a soft matchup. This was the fourth time this season he's gone six innings in a start without allowing a run. He's also posted five quality starts in his last six outings, with the lone exception being the May 30 start that ended with the aforementioned hamstring injury before he could record an out. The right-hander is now at a 2.83 ERA, 1.07 WHIP and 67:16 K:BB through 63.2 innings over 12 starts. Gallen threw 77 pitches (50 strikes) Saturday, so he should be good for a full workload his next time out, which is tentatively projected for a road outing at San Diego.

  • Diamondbacks' Zac Gallen: Reinstated from IL

    Rotowire
    The Diamondbacks reinstated Gallen (hamstring) from the 15-day injured list ahead of his start Saturday versus Oakland. Gallen was able to build up to 67 pitches while throwing bullpen sessions and sim games during his time on the injured list, and it's possible he'll be under a pitch count as he makes his first start since May 30. In a corresponding move, Brandon Hughes was optioned to Triple-A Reno.

  • Diamondbacks' Zac Gallen: Could return Saturday

    Rotowire
    Gallen (hamstring) could be activated from the 15-day injured list to start Saturday against Oakland if he recovers well from Thursday's bullpen session, Alex Weiner of ArizonaSports.com reports. Thursday's bullpen session will be the second one thrown by Gallen, who also has a couple of simulated games under his belt since he landed on the injured list. The right-hander hasn't appeared in a game since May 30, when he threw just six pitches against the Mets before being removed due to the hamstring strain.

  • Diamondbacks' Zac Gallen: Another sim game coming next week

    Rotowire
    Gallen (hamstring) is scheduled to throw another simulated game early next week and could be reinstated from the 15-day injured list shortly thereafter, Theo Mackie of The Arizona Republic reports. After tossing 31- and 37-pitch bullpen sessions last week, Gallen advanced to facing hitters in a simulated game Tuesday. Gallen's strained right hamstring apparently responded well to the workout, but the Diamondbacks will still have him toss another sim game during the upcoming week before signing off on his return to the rotation. If all goes well during his second sim game, Gallen could return at some point during the Diamondbacks' series in Oakland next weekend.

  • Diamondbacks' Zac Gallen: Throws on flat ground, bullpen next

    Rotowire
    Gallen (hamstring) threw a flat-ground session Saturday and is expected to throw a bullpen session soon, Jesse Friedman of GoPHNX.com reports. Gallen was cleared for throwing June 3 and was able to complete a flat-ground session Saturday. The next box for Gallen to check in his recovery from a right hamstring strain would be a bullpen session, which should occur in the coming days. Gallen will be eligible to return from the 15-day injured list June 15, though it's unclear if he'll be ready to join the big club by then.
