White Sox purchase Javy Guerra's contract from Knights

The White Sox announced on Tuesday that they have purchased the contract of Charlotte Knights reliever Javy Guerra.

The 28-year-old right-hander went 1-1 with a 2.33 ERA in 14 appearances (19.1 IP) with the Knights this season and will take the roster spot of Matt Lindstrom, who was placed on the 15-day disabled list today by Chicago with a sublexing peroneal (outside) tendon in his left ankle.

Guerra joined Charlotte after being claimed by the White Sox off waivers from the Los Angeles Dodgers on March 26. Guerra -- who saved three games for the Knights this season -- has earned 29 saves at the Major League level over parts of three seasons. He led the Dodgers with 21 saves in 2011 and posted a 2-2 record with a 2.31 ERA in 47 games that season.

The Knights, who begin a two-game set with the Norfolk Tides at 7:05 tonight, are yet to announce a replacement for Guerra on their 25-man roster.
