Hunter Pence wants to play major league baseball again in 2019, and a team should absolutely give him a chance if for no other reason than Hunter Pence is a gem and baseball would be worse with his absence. Even if he replicated his lost 2018 in which he had a .509 OPS, he could still improve some teams. The Marlins gave 298 combined plate appearances to Magneuris Sierra and oyster restaurant JB Shuck and they had a .399 and .486 OPS respectively.
Pence, as you know, has been playing in the Dominican Winter League to try out his new swing.
