1:42pm: Mike Berardino of the St. Paul Pioneer Press has some further detail on Boyer’s deal (Twitter links). Boyer will earn $750K if he makes the big league roster, with an additional $100K available via performance bonuses. His contract also contains a March 30 opt-out clause that can be exercised if he has not been added to the 40-man roster.

10:28am: The Twins have signed right-hander Blaine Boyer to a minor league contract with an invitation to Major League Spring Training, team director of communications Dustin Morse announced (on Twitter).

The 33-year-old Boyer returned to the Majors for the first time since 2011 last season, firing 40 1/3 solid innings out of the Padres’ bullpen. Though he averaged just 6.5 K/9, Boyer showed strong control, averaging just 1.8 walks per nine. His fastball lost very little of its heat despite the two-year gap between big league stints, as he averaged a healthy 93.1 mph on the pitch. Despite his solid season, however, Boyer was outrighted by the Padres following the year. He had projected to earn $1MM in arbitration, via MLBTR contributor Matt Swartz.

The Twins’ bullpen currently features All-Star closer Glen Perkins and several solid, albeit unspectacular setup men. Casey Fien and recent signee Tim Stauffer (another former Padre) will serve as right-handed options for new skipper Paul Molitor, while Brian Duensing and perhaps Caleb Thielbar will join Perkins as southpaws. Others in the mix include righties Ryan Pressly, Michael Tonkin and Lester Oliveros in addition to southpaws Logan Darnell and Aaron Thompson.
