Why He's Here: He entered the Thunder's rotation without any of the hype of teammates Dellin Betances and Manny Banuelos, but as the season wore on it became clear that he was the one of the team's most valuable and effective starters.

It didn't show up in the statistics that would have put him on the prospect map, but he provided something rare for a Thunder hurler last season: Efficiency.

Of his team-best (tied with Craig Heyer) 24 starts, Hall went seven full frames seven times. Combined, Betances, Banuelos, Heyer, Steve Garrison and Graham Stoneburner accomplished that feat on just five occasions. 

Most Memorable Moment: Against Erie on July 19, Hall lasted eight strong innings, allowed just two runs (both earned) and picked up the win. He struck out six against two walks before handing the ball to Pat Venditte, who pitched a perfect ninth.

Outlook for 2012: Unfortunately for Hall, he'll probably get Kontos'd, by which I mean asked to head back to Double-A after a year that warranted a promotion. Unless Betances or Banuelos breaks camp with New York, the Triple-A rotation is looking stocked, which could send Hall back to Waterfront for a return engagement with the Northeast's brisk spring months.
