The New York Yankees have been pleasantly surprised by one of their relief pitchers this season, someone they weren't counting on being so reliable- rookie Preston Claiborne. He made his MLB debut this season and has appeared in 13 games, spanning 18.1 innings. His sparkling 0.49 ERA and 0.71 WHIP are something to behold, but it's his control that has been truly masterful. Claiborne has yet to issue a walk. You read that right, no bases on balls, no free passes, ZERO WALKS!
The 25 year old right-hander was decent in the minors, but not nearly as remarkable as he's been in the Big Show. Over 4 minor league seasons, he pitched 204.1 innings and issued 79 walks (3.5 BB per 9 IP). However, the 17th round draft pick of 2010 has been pitch perfect out of the Yankees bullpen and will soon begin working high leverage innings with the more trust he gains from manager Joe Girardi.
I wonder what the record for innings pitched without issuing a walk to being a MLB career is?
