Hermsen, 23, was added to the 40-man major-league roster in the offseason and attended his first big-league spring training. He got into two spring training games, compiling a 13.50 earned run average in 2 2/3 innings.
According to a report on the Twins Website, Hermsen also was "hit hard in a 'B' (spring training) game and an intrasquad game."
Hermsen was the Twins' minor-league pitcher of the year last season, going 12-6 with a 2.88 earned run average in 26 combined starts at high-Class A Fort Myers and New Britain. Minnesota General Manager Terry Ryan said all players reassigned to minor-league clubs Monday may not necessarily begin the 2013 season with those clubs.
He said players have the opportunity to improve their status, if you will, depending on how they fare on the minor-league side of spring training."That's just where we assigned them, so don't get too carried away with that," Ryan said. "They can move up or down depending on how they do over there. We always like to send a guy where we think they belong but they have an opportunity to get out of there."
