Wilhelmsen was released by the Mariners in November. The 33-year-old split his 2016 run between the Rangers and Mariners, pitching to a combined 6.80 ERA, 3.7 BB/9 and 5.4 SO/9 that reflected a tough stretch in Texas during the first half of the season. His career stats should give the Diamondbacks some reassurance, however, as the righty carries a 3.46 ERA, 4.0 BB/9 and 8.1 SO/9 through six years in the majors. He peaked in Seattle during the 2012 season, putting up a career-best 1.6 fWAR for the club after ousting fellow right-hander Brandon League from the closer’s spot.
Wilhelmsen figures to be in the mix for another major league gig this spring. Many of the Diamondback’s bullpen spots appear to be up for grabs behind right-handers Jake Barrett and Randall Delgado and closer Fernando Rodney, though the team has no shortage of short-term options to consider.
