Keller has rebounded since mid-August with four straight quality starts, yielding three earned runs or less and maintaining a 3.09 ERA and 0.86 WHIP in September. He’s often undervalued, but his reliable innings and shrinking ERA/WHIP help steady fantasy farms entering the final weeks.

Keller carries a high-strikeout ceiling but greater risk of line-drive contact; his ability to strand runners and miss bats shapes Pirates’ chances to limit Milwaukee’s scoring.

Keller anchors the Pirates' strong rotation alongside Skenes, providing veteran steadiness and a steady workload that supports a playoff-aspiring bullpen and offense.

Keller has emerged as a reliable second/third man in Pittsburgh’s rotation, reaching 16 quality starts and delivering a nine‐strikeout outing against St. Louis. Yet August’s 7.88 ERA and the season’s late fade temper his ceiling. If he sustains a durable, innings‐heavy workload and lowers walk rate, he could anchor a 2026 Pirates’ 1–2 with Skenes.

Keller starts for Pittsburgh with a 5-12 record and 4.35 ERA; last outing was rough (13.50 ERA, 5 R, 7 H, 3 BB, 4 K). Fantasy managers watch for improved control and ground-ball tendency to secure Ks and a potential win in STL.
