Pennington (hamstring) was placed on the 15-day DL on Wednesday, Alden Gonzalez of MLB.com reports.
This is a tough development for Pennington as the veteran infielder had played just three games since returning from a hamstring injury before heading back to the DL. The Angels purchased Brendan Ryan's contract in a corresponding move Wednesday to replace Pennington up the middle. However, the Angels will likely use a combination of Johnny Giavotella and Gregorio Petit as their double play combo the majority of the time in Pennington's absence.
