2026 Fantasy Outlook

Rumfield got a welcomed change of scenery this offseason when he was shipped from the Yankees to the Rockies for reliever Angel Chivilli. Rumfield, a 25-year-old lefty first baseman, was not going to break through with the Yankees anytime soon, but the Rockies are expected to have an open competition at first base. While Rumfield has an intimidating 6-foot-5, 225-pound frame, he's actually hit over power, having slashed .285/.378/.447 with 16 homers, an 11.9 percent walk rate and an 18.4 percent strikeout rate in 138 games at Triple-A in 2025. He will be competing with the likes of Troy Johnston, Blaine Crim and Charlie Condon this spring for reps at first base. If he can win a strong-side platoon role, Rumfield could be useful in deeper leagues, particularly in home games. Read Past Outlooks
