9:36am: Haudricourt says not to put much stock into this rumor, since the Mets are looking to add pitching. SI's Jon Heyman wonders if Hart-Maine could happen if the Mets sign Randy Wolf first. Of course, both clubs are after Wolf.
6:58am: Tom Haudricourt adds that it's important to remember that there are countless deals discussed at the Winter Meetings that never go anywhere; hearing a rumor like this doesn't mean we should immediately expect it to happen. However, Haudricourt also lends credibility to the rumor by pointing out Maine's connection to new Brewers pitching coach Rick Peterson.
1:55am: Joel Sherman provides us with a new rumor, stating that he's learned the Mets and Brewers are discussing a swap of John Maine and Corey Hart. He adds that the Mets are also discussing Kevin Millwood with the Rangers.
Maine and Hart both had down years in 2009, as Maine found himself limited to just 81.1 innings due to injury, while Hart posted a line of .260/.335/.418 and watched his slugging percentage continue to trend downward for the second straight season.
Both players will be arbitration eligible for the second time this season. Maine made $2.6MM last year while Hart earned $3.25MM.
The Brewers would likely welcome the chance to add an arm, though Maine's injuries the past two seasons have to be a red flag. In a similar vein, while Hart has shown in the past that he can be the power-hitting, right-handed corner outfielder the Mets want, his .418 slugging percentage and 12 HR in 2009 are a long way removed from his 24 HR and .539 slugging percentage of 2007.
