Tigers starter Michael Fulmer will undergo season-ending ulnar transposition surgery Tuesday, reports Anthony Fenech of the Detroit Free Press. The right-hander is expected to need between three and four months for recovery, and should be ready for full baseball activity next spring.
Fulmer, a 2011 first-round pick, has shown flashes of brilliance in his two major league seasons, with a 3.45 ERA and 1.137 WHIP across 323.2 innings. The 24-year-old took home AL Rookie of the Year honors in 2016, with an impressive 11-7, 3.06 ERA campaign as the Tigers' number two starter. Under team control through 2022, Fulmer figures to be the ace of Detroit's staff for the foreseeable future.
The Tigers acquired Fulmer from the Mets in exchange for outfielder Yoenis Cespedes in July of 2015.
