J.D. Martinez, who has an opt-out in his contract with the Boston Red Sox after the season, says the number of variables this year make him not want to test free agency.

The coronavirus pandemic and 60-game shortened season has led to an unstable market and questions about player evaluation this year.

"I don't know how [player evaluation] is going to happen," Martinez said. "I honestly feel like I would not want to be a free agent during this time for that reason. You just don't know. Everything is up in the air for guys like that. It's weird."

Martinez, 33, has struggled this season for the Red Sox, hitting .218/.305/.387 with three homers, 17 RBIs and 12 doubles in 124 at-bats.

He signed a five-year, $110 million deal with Boston prior to the 2018 season, with opt-outs after 2019, '20 and '21.
