Zac Gallen Strikes Out 13

Arizona Diamondbacks starting pitcher Zac Gallen looked untouchable on Wednesday, striking out 13 batters over 6 shutout innings in a 4-3 win against the Yankees. The Yankees and their torpedo bats have gained a lot of attention over the recent days, but the bats don't matter if they don't make contact. Gallen collected 24 whiffs on the night for a whiff rate of 57%. His knuckle curveball was the most effective of his pitches, collecting 13 whiffs all on its own. He'll look to carry this momentum into his next start, currently lined up to be against the Orioles.

Zac Gallen Solid On Thursday Against The Athletics

Arizona Diamondbacks right-hander Zac Gallen had a respectable outing in Thursday's spring training matchup against the Athletics. He threw 4 innings, allowing five hits, two walks, two strikeouts, and one earned run. It was nothing flashy, but it was a good outing he can build off of, as Opening Day is less than a week away. Gallen has already been named the team's Opening Day starter for next Thursday, March 27, against the Chicago Cubs. Last season, Gallen saw a bit of a dip in production as his 3.47 ERA in 2023 rose to 3.65 in 2025. Gallen's strikeout rate also fell to a career-low 25.1%. Nonetheless, Gallen is a proven starter in the MLB. He should provide fantasy managers with a productive season, even with the D-backs bringing on Corbin Burnes during the off-season.

Zac Gallen To Start On Opening Day For Diamondbacks

Arizona Diamondbacks right-hander Zac Gallen will be the team's Opening Day starter next Thursday, March 27, against the Chicago Cubs, according to MLB.com's Steve Gilbert. It's a bit of a surprise that the D-backs didn't go with offseason acquisition Corbin Burnes, but instead they'll roll with the 29-year-old Gallen for the third straight year on Opening Day. Gallen has a little pressure off of him at the top of Arizona's rotation now that Burnes is in tow. He's not a fantasy ace by any means, but he makes for a solid No. 3 fantasy starter and should be rolled out there in his first start of the year against the Cubs. Gallen's strikeout rate fell to a career-low 25.1%, but he's notorious for being one of the best strike-throwers in the game. It seems unlikely that Gallen will ever be a fantasy ace again like he was in 2022, but you could do a lot worse as your SP2 or SP3.

Diamondbacks Avoid Arbitration With Zac Gallen

The Arizona Diamondbacks avoided salary arbitration with right-hander Zac Gallen on Thursday by settling on a one-year, $13.5 million deal. In addition to Gallen, the D-backs also agreed to one-year deals with right-handers Kevin Ginkel and Ryan Thompson, left-handers Joe Mantiply, Kyle Nelson and A.J. Puk, and infielders Josh Naylor, Geraldo Perdomo and Pavin Smith. The 29-year-old Gallen will be Arizona's No. 2 starter in 2025 after they signed Corbin Burnes in free agency. Gallen missed time with a hamstring injury in 2024 and finished with a 3.65 ERA, 1.26 WHIP, 156 strikeouts and 54 walks in 148 innings pitched. He's a very strong major-league pitcher but comes short of being an elite fantasy ace because of his 26.6% career strikeout rate. Gallen needs to return to his pinpoint control of the strike zone to deliver value as a second fantasy starting pitcher.

Zac Gallen Dominates With 11 Strikeouts In Win

Arizona Diamondbacks starting pitcher Zac Gallen tossed six innings of one-run ball in Wednesday's 8-2 victory over the Giants, allowing just two hits and two walks while striking out a season-high 11 batters on the way to earning his 14th win of the season. The 29-year-old has had another solid, albeit somewhat inconsistent, season for the D-backs, as he allowed one run or less in 13 of 28 starts but four runs or more on seven occasions. Nevertheless, the righty finishes the regular season on a high note and leaves his team one game up on the Braves for the final Wild Card spot with three games to go against the Padres. The former All-Star closes the 2024 regular season at 14-6 with a 3.65 ERA (3.86 SIERA), 1.26 WHIP, and a 16.4% K-BB%.

Zac Gallen Throws Six Innings Of No-Hit Ball In Win

Arizona Diamondbacks starting pitcher Zac Gallen tossed six innings of no-hit ball in Wednesday's 6-4 victory over the Giants but was pulled after 100 pitches despite the no-hitter in progress. The 29-year-old walked four batters in the contest which pushed his pitch count higher, but he also struck out eight batters before handing the game over to the bullpen. The former All-Star notched his 11th quality start and picked up his 11th win of the season, now 11-6 with a 3.69 ERA, 1.28 WHIP, and 14.8% K-BB%. The righty will square off with the Rangers at home in his next start on Tuesday of next week.

Zac Gallen Wins Saturday, Fans Nine Hitters

Arizona Diamondbacks right-hander Zac Gallen beat the Boston Red Sox on Saturday afternoon 4-1, fanning nine hitters while surrendering two hits and four walks. Gallen is now 10-6 with a 3.65 ERA, a 1.30 WHIP, and 111 strikeouts in 116 innings. The veteran has battled inconsistency all season and is 1-1 with a 4.03 ERA and 1.52 WHIP in August with 19 strikeouts in 22 innings. This month, he has also coughed up 10 earned runs and 10 walks. If the Diamondbacks are going to make a playoff run this season, they will need Gallen to be his usual stalwart self for the last six weeks of the season.

Zac Gallen Cleared To Start On Saturday

Arizona Diamondbacks starting pitcher Zac Gallen (cramps) has been cleared to start on Saturday. The right-hander exited his previous start early due to general cramping, but this does not seem to be a major concern. Gallen logged just four 1/3 innings and allowed one earned run while striking out three. While the 29-year-old has had some struggles this summer, he currently sits with a 3.69 ERA, 1.28 WHIP, and a 35:99 BB:K ratio across 105 innings of work. Under the hood, Gallen boasts an above-average 6.2% barrel rate and 46.9% ground-ball rate. This afternoon, he will face the Tampa Bay Rays in a favorable matchup as they strike out at a 24.2% K rate against right-handed pitchers. Gallen should be in all fantasy lineups going forward and a popular play in DFS today.

Zac Gallen Removed Early From Saturday's Start

Arizona Diamondbacks starting pitcher Zac Gallen (cramps) was removed early from Saturday's start due to general body cramps. Jesse Friedman reports that Gallen is not expected to miss any time. The right-hander logged four 1/3 innings before exiting but fantasy managers should not need to worry as Gallen should be in line to make his next start against the Tampa Bay Rays. The 29-year-old has struggled at times this season by serving up at least four earned runs three times in his past seven starts. Overall, through 105 frames of work, Gallen sits with a 3.69 ERA, 1.28 WHIP, and a 35:99 BB:K ratio. Gallen should remain in all fantasy lineups and will be a popular play in DFS in his next start against the Rays.

Zac Gallen Picks Up Third Straight Win

Arizona Diamondbacks starting pitcher Zac Gallen produced a solid outing in Wednesday afternoon's victory over the visiting Washington Nationals at Chase Field, striking out six batters over six innings in his start. Gallen gave up one run on six hits and one walk in Wednesday's showing against Washington, picking up his third consecutive win. The 28-year-old workhorse right-hander will still be looking to turn the page on what was a rough month of July despite the three straight victories for him, after posting a 5.10 ERA and 1.63 WHIP with 25 punchouts and 15 walks across his last six starts (30 frames) for the D-backs. Tuesday's showdown against the first-place Cleveland Guardians marks Gallen's next scheduled appearance for Arizona.
