The Athletics announced 31 non-roster invites spring training, including prized shortstop prospect Leo De Vries plus starting pitchers Gage Jump and Jamie Arnold.
De Vries was the centerpiece the Padres sent back to the A’s for Mason Miller last season and is considered one of the best prospects in baseball. It’s customary for top prospects to get an invite to major league spring training, especially when they’ve already reached Double-A like De Vries did last season. It’s unlikely the 19-year-old is ready to compete for a major league roster spot yet though. Of this trio, Jump has the best chance to reach the majors in 2026 after breaking out with a 3.28 ERA, 1.10 WHIP, and 131/34 K/BB ratio across 112 2/3 innings between High-A and Double-A last season.
