Diamondbacks' Zac Gallen: Continues turnaround with nine Ks
Rotowire
Gallen (7-9) earned the win over San Diego on Monday, allowing an unearned run on five hits and one walk while striking out nine batters over six innings.
The only run Gallen gave up in the contest was the result of a throwing error in the first inning. Otherwise, the right-hander cruised, as he racked up 13 whiffs and nine punchouts while giving up zero extra-base hits. Gallen posted an ugly 6.23 ERA over five starts in June, but he's rebounded in impressive fashion this month -- through two July starts, he's allowed just one earned run while posting a 19:1 K:BB over 13 frames. His season ERA is still below his usual standard at 5.15, but Gallen appears to be back on the right track given his two most recent starts.

Diamondbacks' Zac Gallen: Strikes out 10 in win
Rotowire
Gallen (6-9) allowed two runs (one earned) on five hits and struck out 10 without walking a batter over seven innings to earn the win over the Giants on Tuesday.
Gallen had allowed at least four runs in eight of his previous nine starts, pitching to a 6.97 ERA in that span. He was much better Tuesday, overcoming a shaky second inning to put together one of his best starts of the season. Gallen's extended slump is still evident in his 5.45 ERA, 1.37 WHIP and 98:42 K:BB through 104 innings, but he could turn things around, as those ratios are the worst of his career. The right-hander will look to build some positive momentum in his next start, tentatively scheduled for this weekend at home versus the Royals.
Gallen (5-9) took the loss Wednesday as the Diamondbacks fell 7-3 to the White Sox, coughing up five runs on eight hits and a walk over 5.1 innings. He struck out two.
Homers by Andrew Benintendi in the first inning and Lenyn Sosa in the fourth accounted for most of the damage off Gallen. The right-hander has served up nine long balls in his last five starts and been tagged for at least four earned runs in eight of his last nine trips to the mound, a brutal stretch in which he's posted a 6.97 ERA, 1.59 WHIP and 39:21 K:BB in 51.2 innings. Gallen will try to right the ship in his next outing, which lines up to come at home early next week against the Giants.
Gallen (5-8) picked up the win Friday, surrendering seven runs on 10 hits and a walk over five innings in a 14-8 victory over the Rockies. He struck out five.
In a classic Coors Field offensive free-for-all, Gallen got rocked for six runs in the fourth inning, including homers by Ryan McMahon and Mickey Moniak. Arizona retook the lead in the top of the fifth, however, and the right-hander got through the minimum frames necessary to qualify for the win. The seven runs allowed tied Gallen's season-worst performance, and he'll carry a 5.60 ERA, 1.40 WHIP and 86:41 K:BB through 91.2 innings into his next outing, which lines up to come on the road next week against the White Sox.
Gallen allowed four runs on six hits and four walks while striking out six over 6.1 innings in a no-decision Saturday versus the Padres.
Gallen pitched well until the seventh inning, when he allowed three of the first four batters he faced to reach base. Ryan Thompson couldn't stop the Padres' rally, which cost Gallen a chance at the win, though the Diamondbacks pieced together a comeback for a walk-off in the ninth. This was the fourth time Gallen has walked a season-high four batters, and it continues a rough stretch for him, as he's now allowed four or more runs in six of his last seven starts. He's at a 5.19 ERA, 1.35 WHIP and 81:40 K:BB across 86.2 innings through 15 starts this season. His next outing is projected to be at Colorado.

Diamondbacks' Zac Gallen: Allows three homers in loss
Rotowire
Gallen (4-8) took the loss against the Reds on Sunday, allowing four runs on six hits and three walks with five strikeouts over 6.2 innings.
Gallen was locked in a 2-2 tie through six innings before surrendering a go-ahead two-run homer to Matt McLain with two outs in the seventh. The 29-year-old was ultimately undone by the long ball and continues to struggle with his control, having issued three or more free passes in eight of 14 starts this season. He'll carry a 5.15 ERA, 1.33 WHIP and 75:36 K:BB across 80.1 innings into a home matchup with the Padres next weekend.
Gallen (4-7) earned the win Tuesday in Atlanta after giving up three runs (one earned) on four hits and one walk over seven innings. He struck out four.
The right-hander pounded the zone with 65 of his 89 pitches going for strikes, and the single walk marks the first time he hasn't issued multiple free passes in a start since April 2. Gallen entered Tuesday with an 8.02 ERA and 17:11 K:BB in his previous four starts, but he was able to get back in the win column with his fifth quality start of the campaign. He'll carry a 5.13 ERA and 1.33 WHIP over 73.2 innings into his next start, which tentatively lines up for Sunday in Cincinnati.
Gallen (3-7) took the loss against the Pirates on Wednesday, allowing six runs (five earned) on six hits and three walks with three strikeouts over five innings.
Gallen entered the sixth inning with a shot at a quality start but was unable to record an out and was ultimately charged with three runs in the frame. The 29-year-old has now allowed at least four earned runs in four consecutive outings and in seven of his 12 starts this season. He'll take a disappointing 5.54 ERA, 1.40 WHIP and 66:32 K:BB across 66.2 innings into a road matchup with Atlanta next week.

Diamondbacks' Zac Gallen: Pairs well with Herrera
Rotowire
Arizona manager Torey Lovullo had Jose Herrera catch Gallen for Friday's series opener against St. Louis, after the pitcher had struggled in his previous outing, Joe Harris of MLB.com reports. The right-hander threw five strong innings before running into trouble in the sixth in a 4-3 loss.
It's been a rough start to the 2025 season for Gallen, whose 5.25 ERA is the highest its been since he became a full-season starter in the majors. However, when Herrera has caught him, Gallen's ERA is 3.56 compared to 6.89 when Gabriel Moreno is behind the dish. "We got a pretty good relationship," Gallen said. "I think he knows what I'm looking for out of the shapes of my pitches. He kind of knows when certain things aren't right, not necessarily to shy away from those pitches, but use them a little differently. So yeah, there's definitely a comfort there." Given the pitcher's results thus far, Lovullo may opt to pair Gallen and Herrera going forward.

Diamondbacks' Zac Gallen: Struggles continue in sixth loss
Rotowire
Gallen (3-6) took the loss Friday against the Cardinals after allowing four runs on three hits and four walks in 5.2 innings. He struck out four.
Despite giving up just three knocks, Gallen yielded at least four runs in his third straight start. The veteran right-hander also tied a season worst in walks, and it was a bases-clearing triple by Nolan Arenado that drove in a trio of runs in the sixth inning to end the hurler's night. Gallen continues to struggle in 2025, as he holds a 5.25 ERA, 1.36 WHIP and 63:29 K:BB across 61.2 frames, but he'll have a prime opportunity to get back on track his next time out versus the Pirates, who are scoring a lowly 2.5 runs per game over their last 28 outings.

Diamondbacks' Zac Gallen: Rocked by lowly Rockies
Rotowire
Gallen allowed six runs on eight hits and two walks while striking out five batters over five innings in a no-decision against Colorado on Saturday.
Gallen fell behind early, as a pair of Rockies homers resulted in three first-inning runs. The right-hander went on to give up two more long balls before his outing came to an end, though an explosive Arizona offense saved Gallen from taking a second straight loss. Gallen has had an up-and-down season so far -- he's collected four quality starts but has also surrendered four or more runs in five different outings. Overall, he's pitched to an uncharacteristically poor 5.14 ERA, which is on pace to be the worst mark of his career by a wide margin.

Diamondbacks' Zac Gallen: Knocked around by Dodgers
Rotowire
Gallen (3-5) allowed four runs on 10 hits and two walks while striking out five over 5.2 innings to take the loss Sunday versus the Dodgers.
Gallen was able to keep the ball down on his watch, but the Dodgers still scraped together plenty of offense. After allowing just two runs over his previous 13 innings, this was a step back for Gallen, though it was far from a disaster. The veteran right-hander now has a 4.59 ERA, 1.31 WHIP and 54:23 K:BB across 51 innings through nine starts this season. He's got a favorable matchup ahead, as he's projected for a home start against the Rockies when he next takes the mound.
