Derek Holland has opted out of his minor-league contract with the Red Sox and is now a free agent, as was first reported by MassLive.com’s Chris Cotillo earlier Sunday morning.

Holland, 35, originally signed a minor-league deal with Boston back in March with the hopes of earning a bullpen spot with the team out of spring training. When he was informed that he would not be making the Sox’ Opening Day roster, the veteran left-hander elected to remain in the organization and begin the season with Triple-A Worcester.

In 10 relief appearances for the WooSox, Holland posted a 6.35 ERA to go along with 13 strikeouts to seven walks over 11 1/3 innings of work. Given that the Red Sox already have lefties like Austin Davis, Jake Diekman, and Matt Strahm in their bullpen with another southpaw rehabbing from injury in Josh Taylor, adding Holland to the major-league mix was clearly not a priority for the club.

Instead, Holland — who had multiple opt-out clauses in his contract since he was an article XX(B) free agent — will once again hit the open market and look to latch on elsewhere.

A former 25th-round draft pick with 13 seasons of big-league experience under his belt, Holland his pitched for the Rangers (2009-2016), White Sox (2017), Giants (2018-2019), Cubs (2019), Pirates (2020), and Tigers (2021). With Detroit last year, he produced a 5.07 ERA and 3.96 FIP across 39 appearances (one start) spanning 49 2/3 innings.
