A blurb from BA from the 2009 Draft, signed at 4th rd pick for 365K:
Hailing from Arnett, Okla., Henry was slated to attend Texas Tech after high school. But he blew out his elbow, missed his senior season after having Tommy John surgery and ended up at South Mountain CC. He's played second base for the Cougars this year, but his future is likely on the mound. At 6-foot-3, Henry has clean mechanics from a three-quarter arm slot. Just 18 months removed from surgery, head coach Todd Eastin gave Henry a very soft landing this year, allowing him to pitch out of the bullpen. Over nine games, Henry pitched just 11 innings this season. Because of his limited time on the mound this year, Henry has been tough to see, but those that have seen him walked away impressed. His fastball has shown good life, sitting at 90 mph every time out and even touching 94-96 late in the year. While Henry threw mostly fastballs and changeups this year, when he regained the confidence to throw a breaking ball, scouts said it was an above-average pitch with great tilt and snap.

BA updated profile:
Henry is an athletic righthander whose best offering is a plus slider that features sharp, late break and tops out at 87 mph. His fast arm produces 91-94 mph fastball velocity with good arm-side run, but he's still developing a below-average changeup. A 2009 draft pick, Henry spent the majority of the 2011 season in low Class A and injury concerns have been an issue in the past. He endured two separate disabled list stints in 2010 for right elbow inflammation. Though the Rangers will try out Henry as a starter, the combination of his aggressive approach and two above-average pitches profile well as a potential seventh- or eighth-inning reliever.
Henry missed the first 6-7 weeks of the season so one has to assume that his elbow was still bothering him this spring. Given his health issues the last 2 years I'm not sure why the word from Texas is that they like him as a starter (I think that came from Daniels via TRS).
Digging around a little I found out that Henry had surgery again on August 11 2010 after his two DL stints. It was supposed to be a second TJ surgery but the docs only found broken up scar tissue rather than any damage to the ligament replacement. So this likely explains why he missed the beginning of the year; he was still rehabbing from the surgery rather than dealing with a new setback, so that is good news, news Texas already knew of course, which gives credence to their willingness to look at him in the roto for 2012. I also found a note that he was working on a cut fastball in 2011.
Henry's timeline is something like this:
TJ before Senior Year (fall o7 or Spring 08); missed SR year 08; pitched 11ip out of the pen for a JC in 2009 but mostly played 2nd base; drafted by baltimore in the 4th round in 2009, but didn't pitch in the minors; pitched 23 innings out of the pen for Delmarva, Low A, in 2010, punctuated by two stays on the DL, and an exploratory surgery on his TJ elbow on August 11; Rehabbed from surgery the first 6-7 weeks of 2011 season; Pitched 53 innings (LowA June/July; HighA August) out of the pen in 2011 after being activated without a DL stay and finished the year healthy.
