Mitch Keller: Everything you need to know

Keller (5-3) was tagged with the loss Friday against Atlanta, allowing six runs on seven hits and three walks across 4.2 innings. He struck out four and also hit a batter. Keller enjoyed an excellent start to the season, and while some regression was expected, he's been hit hard of late. He's given up four or more runs in four of his last five appearances, a stretch in which he's gone 1-2 while posting an 8.31 ERA and 1.58 WHIP with a 20:9 K:BB across 26 innings. Keller has now fallen short of five innings in his last two appearances. Keller won't have an easier outing next time around since he's scheduled to face the Dodgers at home next week.

Keller did not factor into the decision in Saturday's 10-9 win over the Twins, allowing seven runs on 10 hits and one walk with five strikeouts over four innings. Keller was given an early 7-1 lead in the second inning but allowed five runs in the fourth while surrendering five extra-base hits overall. The 30-year-old endured an uneven May, yielding two earned runs or fewer in three starts but 17 total across his other three, resulting in a 5.50 ERA for the month. He'll carry a 4.35 ERA, 1.17 WHIP and 51:20 K:BB across 68.1 innings this season into a road matchup against Atlanta next weekend.

Keller (5-2) earned the win against the Blue Jays on Sunday, allowing one run on four hits and three walks with five strikeouts over six innings. Keller allowed three baserunners and a run in the fourth inning but was otherwise solid, generating 11 whiffs on 101 pitches while limiting the Blue Jays to one extra-base hit. It was a nice rebound for the 30-year-old after allowing 10 earned runs over his previous two outings, and he's now logged seven quality starts while working into the sixth frame in nine of 11 appearances this season. He'll carry a 3.64 ERA, 1.07 WHIP and 46:19 K:BB across 64.1 innings into a home matchup against the Twins next weekend.
