According to La Velle E. Neal of the Minneapolis Star-Tribune, the A's claimed lefty reliever Craig Breslow off waivers from the Twins. The Twins called up Anthony Swarzak in his place. Breslow, a 28 year-old Yale alum, posted a 6.28 ERA in 14.3 innings this year. Last year, though, he posted a 1.91 mark in 47 innings.
Swarzak, a righthanded starter, ranks as the Twins' 6th-best prospect according to Baseball America. BA says he has a plus fastball and curveball.
