Twins to call up Samuel Deduno and PJ Walters for starts this weekend

The Minnesota Twins have officially called up Samuel Deduno to start Friday's game against the Tigers. In addition, P.J. Walters will be brought back up to the major league squad to start a game on either Saturday or Sunday, reports Jim Mandelaro of the Rochester Democrat and Chronicle.

The two pitchers will help fill the hole in the Twins' rotation created by Vance Worley's demotion to Triple-A Rochester. Following that move, the Twins had just Kevin Correia, Scott Diamond, and Mike Pelfrey listed on their depth chart at starting pitcher.

Deduno, 29, has missed much of the season due to a strained groin that he suffered during the World Baseball Classic. He returned in early May and has pitched well in three starts for Rochester, posting a 2.70 ERA. He spent about half of 2012 in the majors with Minnesota, making 15 starts with a 4.44 ERA.

However, Deduno has had significant control issues and walked six batters per nine innings. Deduno's tendency to give up walks has existed throughout his career and has not been quelled in the minors this year.

Walters, 28, also spent a significant amount of time in the Twins' rotation in 2012. He did not have as bad of control issues as Deduno, but posted a 5.69 ERA over 12 starts. Walters has also pitched well in Rochester this season with a 3.31 ERA over nine starts.

It's unclear which day Walters will start over the weekend. Correia and Pelfrey are slated to pitched on Saturday and Sunday, respectively. One or both would need to be pushed back for Walters to start.
