Rollins_twitter
You may have seen the scoreboard video of Rollins and his teammates saying that they don't use Twitter, but at some point between when the video was shot in the beginning of spring training and March 17th, Rollins decided he would start using the service (mostly thanks to his sponsor, Red Bull).

Today, he updated us on the status of his knee, which he fouled a pitch off of on Saturday. Somewhere, Bill Conlin's head just exploded- Bill Lyon writing for an online-only site, J-Rollâ„¢ updating injuries on Twitter, Jobs announcing Skynet. Oh yeah, the Rapture is near.
