18. Luke Voit
Luke Voit was one of the biggest second-half surprises of the 2018 season, as the Yankees took a flier on the first baseman to fill a glaring hole in their lineup.
Voit did not just fill a need for New York but he also became one of their best power hitters and run producers.
In 39 games with the Yankees, Voit hit .333 with 14 home runs and drove in 33 runs. Now that the Yankees have seen what Voit can do, albeit in a small sample size, he figures to feature prominently in their plans moving forward.
