3:17pm: A high-ranking Diamondbacks official tells MLB.com's Steve Gilbert that no offer has been made to Chamberlain (Twitter link). Ken Rosenthal of FOX Sports tweeted earlier, however, that Chamberlain does indeed have a one-year, $3MM offer. Money isn't the driving factor for Chamberlain, however, according to Rosenthal.

2:56pm: The D-Backs have made a one-year offer to Joba Chamberlain worth roughly $3MM, tweets ESPN's Buster Olney.

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.
