Twins' Pineda comes off IL, to start Thursday
Pineda had been on the IL since Aug. 3 with a right triceps strain. He has made 21 starts this season and is 7-5 with a 4.15 ERA.
In a corresponding move, the Twins optioned right-hander Randy Dobnak to Triple-A Rochester.
Dobnak made his major league debut with Minnesota on Friday, pitching four scoreless innings during a loss to the Cleveland Indians.
