Yields four runs in no-decision Gallen did not factor into Tuesday's decision against Miami. He allowed four runs on nine hits and one walk while striking out three across 5.1 innings.

Impact It was the second-straight start that Gallen gave up nine hits and for the third time this season. He's also given up at least four earned runs in three consecutive outings and in six of his last eight starts. Over 69.2 innings, the veteran right-hander has a 5.43 ERA and 1.55 WHIP, both of which are worst in the National League among qualified starters in 2026. Gallen's next start is slated for this weekend on the road against the Reds.

Gets no help in loss Gallen (3-5) allowed five runs (four earned) on nine hits and two walks while striking out one over five innings to take the loss versus the Dodgers on Wednesday.

Impact Kyle Tucker's two-run home run in the second inning was the difference. Gallen didn't get much help -- the Diamondbacks managed just two hits and two walks in the whole game. Gallen has allowed at least four runs in five of his last seven outings, which makes him a risky option for most fantasy managers. On the year, he has a 5.32 ERA, 1.52 WHIP and 43:20 K:BB through 64.1 innings over 13 starts. The veteran right-hander's next start is projected to be on the road versus Miami.

Yields three homers Friday Gallen allowed five runs on eight hits and a walk while striking out two over five innings in a no-decision versus the Mariners on Friday.

Impact Gallen has been falling victim to the long ball more often lately with eight homers surrendered over his last five starts. The Mariners's J.P. Crawford had two of the homers while Julio Rodriguez swatted the other. May was an inconsistent month for Gallen -- he allowed four or more runs in four of his six starts. He's now at a 5.16 ERA, 1.47 WHIP and 42:18 K:BB through 59.1 innings over 12 starts this season. The veteran right-hander's homer problems led to career-worst numbers in 2025, and he's trending in the wrong direction lately. Gallen is projected to make his next start at home in a tough matchup versus the Dodgers.

Collects third win Gallen (3-4) allowed three runs on six hits and two walks while striking out six over 5.1 innings to earn the win Saturday over the Rockies.

Impact Gallen had a fair performance to pick up consecutive wins for the first time this season. He's now allowed just five runs over his last 11.1 innings after opening May with three poor starts. The veteran right-hander is at a 4.80 ERA, 1.44 WHIP and 40:17 K:BB through 54.1 innings over 11 starts this season, numbers largely in line with what he displayed in a down year in 2025. His next start is projected to be on the road in Seattle.

Earns second win Monday Gallen (2-4) earned the win Monday, allowing two runs on four hits and a walk over six innings against San Francisco. He struck out five.

Impact Afforded ample run support, Gallen turned in his second quality start of the campaign en route to his second victory. It was a much-needed positive performance for the right-hander, who had surrendered 14 earned runs across 14.1 innings over his previous three starts. The 30-year-old will carry a 4.78 ERA, 1.43 WHIP and 34:15 K:BB across 49 innings (10 starts) into his next outing, which is tentatively scheduled for Saturday against Colorado.
