Amid a disappointing season, the middle infield has been a rare bright spot for the Miami Marlins.

Adeiny Hechavarria and Dee Gordon have become one of the best double-play combinations in baseball. The only shortstop-second baseman duo with a higher WAR in the National League is Brandon Crawford and Joe Panik of the San Francisco Giants.

"Hechavarria and Gordon are regarded as the two most likely contract extension candidates for the Marlins when they enter the offseason. There is still plenty of games to go, but internally those two are the ones considered priorities to lock up long term," writes Joe Frisaro.

"The Marlins approached Hechavarria last offseason, but talks didn’t go very far. Now, with the shortstop about to enter arbitration, the time is right to get a deal done. Gordon, a Super 2 arbitration player, is making $2.5 million this season. He has three more seasons of arbitration, unless he agrees on a long-term deal."
