The White Sox claimed lefty Leyson Septimo off waivers from the Diamondbacks and optioned him to Double-A, tweets the team. As the team with the fewest players on their 40-man roster (36) the Sox had plenty of room to make the addition. Meanwhile, Arizona's 40-man count drops to 38.
Septimo, 25, has a 6.37 ERA, 6.7 K/9, 7.6 BB/9, and 0.3 HR/9 in 29 2/3 relief innings at Double-A this year. Prior to the 2010 season, Baseball America ranked Septimo 26th among Diamondbacks prospects. The former outfielder was converted to the mound after the '07 season and can touch triple digits with his fastball, according to BA. The White Sox currently have a position player conversion success story in their own bullpen, closer Sergio Santos.
