Miami has the desire to add a starting pitcher, and Lester has notable experience. Lester has pitched to a 10-7 record, 2.52 ERA, and 2.62 FIP in 143 innings pitched for Boston.
Lester may not be Miami's primary target, since he is eigible to become a free agent after the season. The Marlins have made it known that they are seeking a starter who would be under club control for at least next season.
Miami likely has the prospects to get a deal done, and the $4.48 million Lester is owed may not be too overwhelming. The rumor comes after Buster Olney noted earlier in the day that the Marlins could be a surprise candidate for a number of starting pitchers.
Lester would be a valuable addition to a rotation that has pitched well over the past week and a half.
The Marlins have been active after President of Baseball Operations Michael Hill told reporters before the Washington series that he would not consider the Marlins "sellers" with the deadline approaching.
"I would say you could take us out of the seller category and we're just looking for ways to build on what has been a very positive year for us," president of baseball operations Michael Hill said. "We're continuing to try and build and upgrade our talent where we're able to upgrade our talent and make decisions in the near-term, short-term but also help us in the long-term.:
-The Marlins did identify Wade Miley of the Diamondbacks as a potential target to fit the need for a starting pitcher, but Ken Rosenthal noted on Tuesday that Arizona is not interested in trading Miley.
-Miami has also reportedly been interested in Oakland starter Tommy Milone and reliever Jim Johnson, and Chris Cotillo of MLB Daily Dish said Tuesday he would not be surprised if a deal gets done between the Marlins and A's featuring those two players.
