David Rollins

Rollins, a lefthander who endured two surgeries on his non-throwing shoulder, has a better three-pitch mix than teammate Miguel Pena but not as much command. The 6-foot-1, 195-pounder has an 88-91 mph sinker, a slider with bite and a good changeup. He has been drafted in each of the last three years, by the Dodgers in the 19th round in 2008 and by the Mariners in the 23rd round in 2009 and the 46th round last year. Like Pena, Rollins has signed with Lubbock Christian for 2012.
