MINNEAPOLIS -- Right-hander P.J. Walters joined the Twins at Target Field on Thursday and said he's looking forward to making his first start on Saturday.
Walters, 27, had his contract purchased from Triple-A Rochester on Wednesday after left-hander Matt Maloney was designated for assignment.
Walters made six starts with the Red Wings, posting a 2.70 ERA with 25 strikeouts and six walks. Saturday will mark his fifth career big league start, as he has a career 7.24 ERA in 20 games with the Cardinals and Blue Jays.
He said he heard of the news late Wednesday, when Triple-A manager Gene Glynn called him to tell him he'd be joining the Twins rotation with left-hander Francisco Liriano headed to the bullpen.
"Obviously, I was excited," Walters said. "He just kind of told me I was going up and pitching on Saturday, so make the most out of the opportunity."
Walters, who said he throws a fastball, cutter, curveball and changeup, said he hopes his big league experience will serve him well, but that he always gets butterflies before every start.
"There's nerves, even in Triple-A, there's nerves," Walters said. "You care about what you're doing, you try to win. It doesn't matter where you're pitching."
