Riley Greene vs Michael Wacha

The Almanac's Take

Riley Greene, a lefty facing righty Michael Wacha, holds the platoon edge here, and his season line backs it up — .285/.373/.471 with a .844 OPS and 15 home runs across 416 plate appearances. Wacha is a functional mid-rotation arm with a 3.66 ERA and 1.17 WHIP, but his 7.3 K/9 isn't a swing-and-miss profile that neutralizes a disciplined hitter — Greene's 12.3 walk rate suggests he won't chase. The 23-PA head-to-head is too thin to weight; Greene is hitting .190 in that sample, but that's a footnote, not a signal. The season-level platoon read is the real case here.
