According to the Minneapolis Star-Tribune, Twins right-handed pitcher PJ Walters could return Saturday against Kansas City if two bullpen sessions this week are successful.
The 28-year-old started 2012 in Triple-A and pitched to a 3-1 record with a 2.70 ERA before earning a promotion to Minnesota. With the Twins, he was 2-2 with a 5.40 ERA before hitting the 15-day Disabled List with shoulder issues.
Walters made short appearances in Major League Baseball in 2009 (16 innings, 9.56 ERA) and 2010 (30 innings, 6.00 ERA) with the St. Louis Cardinals and in 2011 with the Toronto Blue Jays after coming over in the Colby Rasmus-Edwin Jackson deal.
At the very least, a healthy Walters will provide Ron Gardenhire with extra rotation depth.
