The players

Braxton Ashcraft

A 6-foot-5 southpaw who posted a 2.71 ERA last year with an equally impressive 2.78 FIP, and is penciled in as the third starter in the Pirates' rotation.

Parker Messick

A Guardians prospect who showed great promise last year, demonstrating elite control with all five of his pitches and is expected to be called up by May.

Jacob Lopez

A 27-year-old left-hander who had a phenomenal four-game stretch last year where he didn't allow a single run, and has shown great promise in several other outings.

Tyler Mahle

A 31-year-old right-hander who finished with a 2.18 ERA and 1.13 WHIP over 16 starts for the Rangers last year, and could be a strong asset for his ERA and WHIP ratios in San Francisco.

Riley O'Brien

A right-hander who is likely to split closer duties with JoJo Romero for the Cardinals this season, and could be in line for similar numbers to his 2.06 ERA, 1.15 WHIP, and 6 saves from last year.
