Leiter, 27, has appeared in each of the past two major-league seasons. But he has yet to find much in the way of success at the game’s highest level. Through 107 1/3 MLB innings, most of them in 2017, he carries a 5.03 ERA with 8.1 K/9 and 3.3 BB/9.
A 22nd-round pick in 2013, Leiter put himself in contention for a MLB look with a strong 2016 season at Double-A. He hasn’t actually spent much time at the highest level of the minors, but has shown a bit more strikeout potential there than at his other stops. In 58 1/3 total frames at Triple-A, Leiter carries a 4.01 ERA with 10.5 K/9 and 2.9 BB/9.
