The Brewers have designated Blake Lalli for assignment to clear a 40-man roster spot for Josh Ravin, whom they claimed off waivers from the Reds earlier today, according to MLB Daily Dish's Chris Cotillo (Twitter link).
Lalli, 30, went 3-for-24 with three singles for Milwaukee this season and is 5-for-39 in his brief Major League career. The catcher/first baseman has a much stronger track record at Triple-A, where he has a solid slash line of .268/.312/.420 with 19 homers in 651 plate appearances. Lalli attended Gardner-Webb University in Boiling Springs, N.C. and signed with the Cubs as an undrafted free agent in 2006.
