Journeyman Robbie Grossman is the first position player on this list. In his first and perhaps only year with the Rangers, Grossman got a fair amount of playing time in the outfield or as DH, and he put up okay numbers: .238 ERA with 10 home runs and 49 RBI. He maybe could've made an argument for himself as a reserve bat if it weren't for the fact that rookie Evan Carter is right over his shoulder, breathing down his neck, ready to take his spot in the outfield.
Grossman and Carter already started to trade places in the lineup in September, and then Carter had stellar at bat after stellar at bat in the postseason. At 21 and with only 75 regular season bats, Carter's fWAR already stands at 1.3. After making a name for himself in the postseason, it's almost guaranteed that he's locked up a starting role in left field next season. That will unfortunately leave Grossman, who is 34, left out in the cold.
