TUESDAY: As expected, Bowden has been designated for assignment, according to MLB.com's Carrie Muskat.
SUNDAY: The Cubs will designate Michael Bowden for assignment, Bruce Miles of the Daily Herald reports (on Twitter). The move clears space on the Cubs' active roster for Matt Garza, who had been out with a strained lat. Garza's return will bump Carlos Villanueva to the Cubs' bullpen, which is why the Cubs need to jettison a reliever.
Bowden, 26, has pitched in 14 games out of the Cubs' bullpen in 2013, with a 3.78 ERA, 3.8 K/9 and 2.7 BB/9. In parts of six seasons with the Cubs and Red Sox, he has a 4.47 ERA with 6.7 K/9 and 3.5 BB/9.
