From MLB Trade Rumors:
The 28-year-old former top prospect struggled through his worst season as a Major Leaguer in 2013, posting a 4.93 ERA with 8.1 K/9, 5.6 BB/9 and a 41.5 percent ground-ball rate in 42 innings for the Yankees. Chamberlain was significantly better away from Yankee Stadium, posting a 3.54 ERA on the road compared to a 6.23 mark at home in a roughly equal sample size. Chamberlain’s velocity remained strong, as he averaged a healthy 94.7 mph on his fastball.
I think this was what was so frustrating about watching Joba this past season; the velocity was there but the rest of it was just awful.
Chamberlain will be joining Joe Nathan as a fellow newbie in the “revamped” Tigers bullpen. Maybe going to a different team will turn things around for Joba.
UPDATE: The deal is for one year/$2.5MM
