Martinez, 37, hit .235/.320/.406 (106 OPS+) in 120 games with the New York Mets last season. CBS Sports ranked him as the 44th-best free agent available this winter, noting that "all of his good hitting was contained to May and June, to the extent that he struck out more times in the second half (63) than he reached base (61)."

J.D. Martinez, the former Met and current free agent, isn't officially retired, but he seems to have his post-baseball life ready to go, having signed a deal with a pickleball equipment company with the intention of going pro once he leaves baseball.

Former Red Sox slugger J.D. Martinez is reportedly planning a career in pickleball after baseball, per a recent announcement.
