Central Notes: Grimm, Rodriguez, McDonald

Since picking up Justin Grimm from the Rangers in the Matt Garza deal, the Cubs have liked what they've seen from him in a relief role, writes Mark Gonzales of the Chicago Tribune. Pitching coach Chris Bosio explains that the club is "presenting different roles for him," and Gonzales says that Grimm could stay in the pen going into spring training. On to more links from the AL and NL Central…

• The Pirates have shut down Wandy Rodriguez because of persistent pain and discomfort in his left forearm, according to a statement from GM Neal Huntington. The move will provide more time for the flexor tendon in Rodriguez's forearm to heal and sets him up to be ready for Opening Day 2014, Huntington said.
• Rodriguez says he hasn't considered whether he'll trigger his $13MM player option for next year, Rob Biertempfel of the Pittsburgh Tribune-Review tweets. However, it's unlikely that he doesn't do so, Biertempfel says. The Pirates are on the hook for $7.5MM of the option.
• The Twins don't plan to sign James McDonald, who elected free agency today after being outrighted to Triple-A by the Pirates, Darren Wolfson of 1500ESPN.com says. Minnesota will re-evaluate McDonald and take a look at his medicals over the offseason, however.
