Christian Koss Surges Into Everyday Playing Time Amid Late-Season Spark

Koss has caught fire down the stretch, slashing .333/.383/.548 with three home runs, 13 runs scored, and three stolen bases over his last 14 days. With injuries sidelining Matt Chapman and Willy Adames, Koss has seized everyday playing time as the primary starter at shortstop for a fourth-place Giants club mired in a three-game losing streak.

While his recent power surge is eye-opening—highlighted by his first career multi-homer performance—our baseline models urge caution. With a modest .235 batting average in 2026 and only four home runs across 59 games, this scorching .931 OPS over the past two weeks represents a classic hot streak that is due for sharp regression.

San Francisco embarks on a six-game road trip that opens with exploitable matchups in St. Louis against Quinn Mathews (4.11 ERA) and Matthew Liberatore (5.62 ERA). The weekend set in Los Angeles is daunting against aces Tyler Glasnow and Tarik Skubal (2.88 ERA), but his everyday volume and scorching form make him a worthwhile streamer in standard leagues. Start.
