11:23pm: The deal is a three-year contract worth more than $14MM, FOX Sports' Jon Paul Morosi tweets.
8:26pm: The Rockies are close to signing left-hander Boone Logan to a multiyear contract, Troy Renck of the Denver Post reports. Renck guesses that Logan will be in line for a three-year contract worth around $15MM, a deal similar to what Joe Smith received from the Angels earlier this offseason.
Colorado has been aggressive in pursuing bullpen upgrades this offseason, having already signed veteran LaTroy Hawkins and checking in on a number of other relievers. J.P. Howell was another major Rockies target, with the two sides in serious talks as recently as earlier today, according to Renck.
The Nationals and (Logan's former team) the Yankees had been linked to the southpaw this offseason. Logan posted a 3.23 ERA, 11.5 K/9 and 3.85 K/BB rate in 39 innings with New York in 2013, and underwent arthrosopic surgery in October that removed a bone spur from his left elbow.
