The Diamondbacks have designated southpaw Taylor Guilbeau for assignment, as per a team announcement. The move creates roster space for Joakim Soria, whose deal with the club is now official. Guilbeau has only been a member of the D’Backs organization for a few months, after Arizona claimed him off waivers from the Mariners in October.
The 27-year-old has pitched in each of the last two seasons, posting a 2.70 ERA over 20 innings out of Seattle’s bullpen despite only recording 10 strikeouts and almost matching that total with nine walks. However, Guilbeau did deal with a shoulder problem last season, which could have limited his effectiveness.
Originally a 10th-round pick for the Nationals in 2015, Guilbeau posted much better strikeout totals (20.33K%) and control (6.33BB%) over 347 career minor league innings, while continually posting grounder rates well above the 50 percent threshold. Guilbeau has been a full-time reliever since the start of the 2018 season, so with this intriguing skillset, it’s possible the Diamondbacks could lose him on a DFA claim. If no rival team jumps, Guilbeau can remain in the system as a potential option for a D’Backs bullpen that is short on lefty hurlers.
