Three days after notching his first major league victory, Twins pitcher Cole De Vries is heading back to Class AAA Rochester.

The Eden Prairie native went 1-1 with a 4.20 ERA in three starts, but the Twins optioned him back to Triple-A on Thursday to clear a roster spot for Chris Parmelee, who is heading back to Minnesota after batting .375 with four home runs and 12 RBI in 15 games for Rochester.

The Twins had been hoping to trim back to 12 pitchers on their 25-man roster, allowing them to bolster their bench, and they played short in Kansas City this week with Joe Mauer out with a sprained right thumb.

With off days today and Monday, the Twins can get by with four starting pitchers for now.
