Outlook Mitch Keller

Mitch Keller looks to stabilize after a mixed stretch heading into a home stand

Keller has experienced some turbulence over his last 30 days, posting a 4.85 ERA across 26 innings of work while striking out 18 batters. The Pirates currently sit third in the National League Central with a 53-50 record, relying on Keller as a key piece behind Paul Skenes in a rotation that has dealt with minor shuffling. Recent updates show the team managing a few injuries across the roster, but Keller's active status remains secure as the primary number two starter.

Comparing his recent month-long ERA of 4.85 to our season projection of a 4.24 ERA suggests he has suffered from some poor batted-ball luck and high-traffic innings. His career numbers and overall body of work indicate that this elevated stretch is due for positive regression closer to his baseline. While his strikeout rate has dipped slightly in the short term, his season projection of 165 strikeouts remains an achievable target if he can sharpen his command.

Looking at the upcoming schedule, Keller is lined up for a single start during this scoring period as the Pirates return home to face the Cubs. He will miss the primary two-start landscape, but catching a home matchup against Chicago offers a chance to rebound against a lineup currently featuring mixed production. Evaluate opposing starter metrics and weigh the ratio risks before deploying him, though his overall volume keeps him on the radar. Start.

Outlook Tatsuya Imai

Tatsuya Imai delivers strong recent outings as he locks into the middle of the rotation

Imai has shown positive momentum recently, highlighted by a strong six-inning, one-run performance with eight strikeouts against the Marlins. He slots in as the number three starter for an Astros squad currently sitting in third place in the AL West with a 50-54 record. Despite navigating early-season adjustments and a minor hand blister issue that previously required attention from trainers, he continues to handle a regular workload.

His recent stretch features 23 strikeouts over his last 30 days, pointing to high strikeout upside that aligns with his baseline metrics. While his overall 5.87 ERA through 55.2 innings reflects some early struggles, his recent dominance suggests he is settling into a more sustainable groove rather than running on pure luck.

Looking at the schedule ahead, Imai is not lined up for a two-start week, but his high-strikeout profile makes him an intriguing option. With the Astros continuing their stretch of games, fantasy managers should keep an eye on his matchups and deployment. Verdict: Start.
