Twins optioned RHP Michael Tonkin to Triple-A Rochester.

The Twins needed to send a pitcher out to clear a spot on the roster for Chris Herrmann, and Tonkin was the odd-man out. The 24-year-old posted a 6.35 ERA, 1.77 WHIP and 8/6 K/BB ratio over 11 1/3 innings with the Twins.

This was done as a corresponding move to Josh Willingham being placed on the disabled list. Tonkin has appeared in one game already with the Twins in 2014, working a scoreless inning and striking out one. He'll provide depth to the Twins bullpen.

The Twins plan on recalling Michael Tonkin from Triple-A Rochester on Saturday.

With Josh Willingham heading to the disabled list, Tonkin will provide an extra arm in the bullpen for a few days. The 24-year-old hurler has already appeared in one game with the Twins this season, striking out one in a scoreless inning of work.

Tonkin was only on the active roster for two games. He made one scoreless appearance and will likely be brought back up when the Twins next need relief help.

Tonkin tossed 8 1/3 scoreless innings this spring in the Grapefruit League, but it wasn't enough to earn him an Opening Day roster spot. The 24-year-old right-hander should be near the front of the line for an early-season call-up if the Twins need bullpen help.

Tonkin appeared briefly with the Twins in late August, hurling 2 1/3 scoreless innings of relief. He'll work in the middle innings initially, but could work his way into a setup role if he continues to pitch well.

Tonkin provided the Twins with an extra arm in the bullpen for a few days, but with Liam Hendriks coming up to occupy the rotation spot vacated by Kyle Gibson, Tonkin gets squeezed from the roster again. The 23-year-old hasn't allowed a run in 2 1/3 innings with the Twins this season.

He'll take the place of Kyle Gibson on the active roster. Tonkin made one appearance with the Twins back in July and owns a 2.39 ERA and 60/13 K/BB ratio over 52 2/3 innings this season between Double- and Triple-A. He figures to pitch in middle relief.
