Mitch Keller: Everything you need to know

Keller allowed four runs on four hits and one walk while striking out three batters over 5.2 innings in a no-decision against St. Louis on Tuesday. Keller began his outing with two scoreless frames before giving up a two-run homer to JJ Wetherholt in the third. The Cardinals tacked on another run in the fourth inning, and the final run on Keller's line came after he was pulled with two outs in the sixth. Keller managed just seven whiffs and three punchouts, and he's had four or fewer strikeouts in seven of his 10 starts this season. He's projected to make his next start in Toronto.

Keller (4-2) took the loss Wednesday against the Rockies, allowing six runs on seven hits and a walk across 5.2 innings. He struck out three. Keller cruised through his first four innings, holding Colorado without a hit. However, it was a different story in the fifth -- Keller would give up five straight hits to open the frame, allowing the Rockies to tie the game 3-3, before allowing a three-run homer to Mickey Moniak with two outs to cap a six-run frame. It's the first loss in Keller's last five starts -- he'd held opponents to three runs or fewer in four straight outings coming into Wednesday. His ERA now sits at 3.59 with a 1.08 WHIP and 38:15 K:BB across nine starts (52.2 innings) this year. Keller will look to rebound his next time out, tentatively scheduled for next week on the road in St. Louis.

Keller (4-1) earned the win over Arizona on Thursday, allowing two runs on four hits and two walks while striking out four batters over six innings. Keller trailed 2-1 after three innings, but he finished his outing with a trio of scoreless frames. As usual this season, the right-hander wasn't overpowering -- he managed a modest eight whiffs and four punchouts -- but that didn't prevent him from picking up his fourth victory and sixth quality start through eight outings. Keller's advanced metrics don't pop off the page, but he's getting the job done with a 2.87 ERA, 1.04 WHIP and 35:14 K:BB across 47 frames on the season. He'll draw a promising matchup in what's scheduled to be a home matchup versus Colorado his next time out.
