Tigers signed LHP Derek Holland to a minor league contract.
The club hasn't confirmed yet, but Holland made the announcement via his official Twitter page. The 34-year-old left-hander compiled a bloated 6.86 ERA, 1.40 WHIP and 45/15 K/BB ratio across 40 2/3 innings over 12 appearances (five starts) with the Pirates last season. He'll compete for a spot in the Tigers' Opening Day bullpen and could serve as a swingman, oscillating between the starting rotation and long relief, this season.
