The Cubs have designated right-hander Shawn Camp for assignment and optioned Chris Rusin to Triple-A Iowa to clear roster space for Matt Guerrier and Pedro Strop, according to Gordon Wittenmyer of the Chicago Sun-Times (on Twitter).

Camp, 37, re-signed with the Cubs on a one-year deal worth $1.35MM plus another $200K in incentives this offseason. He appeared in an NL-leading 80 games for the Cubs in 2012, pitching to a 3.59 ERA with 6.3 K/9 and 2.4 BB/9 in 77 2/3 innings. This season has been another story entirely, however, as he's posted a sky-high 7.04 ERA with 5.1 K/9 and 3.5 BB/9.

Both Guerrier and Strop were acquired in trades yesterday. Guerrier was acquired in a swap for Carlos Marmol, while Strop came to the Cubs as part of the return for Scott Feldman.
