Expert Picks for MLB Opening Day:
Joe Ryan Lower Than 6.5 Strikeouts: Joe Ryan is a risky Opening Day starter, showing strikeout potential but coming off a rough Spring Training limited by a lingering back injury. With just 12 innings pitched this spring and below-average metrics, he’s unlikely to go deep, capping his strikeout upside—fade him confidently.
Trevor Story Higher Than 1.5 Total Bases: Andrew Abbott is a prime regression candidate, posting a low ERA last season but with weak underlying metrics and limited strikeout and groundball rates. That sets up Red Sox shortstop Trevor Story, who has historically crushed lefties, to make an impact today.
Zac Gallen Lower Than 4.5 Strikeouts: Zac Gallen enters Opening Day against the Dodgers off a rough 2025 season and a poor spring, showing high hard-contact and barrel rates with limited strikeout upside. With no build-up and a short leash expected, he’s a clear fade for strikeouts.
