Stay ahead of the game and elevate your sports betting experience with SportsGrid.
For the past few seasons, J.D. Martinez has been used almost exclusively as a designated hitter. Despite his one-dimensional profile, Martinez ranks as one of the premier free agents on the market. He's just one season removed from 103 RBIs and has an above-average OPS+ in all but one of his last 11 campaigns. As was the case last year, Martinez will patiently wait for the right opportunity to present itself.
