Kremer allowed no runs off six hits and two walks while recording five strikeouts over 5.1 innings during spring training.
Kremer pitched well over a limited sample this spring, but he'll still likely begin the season in the minors. The 24-year-old recorded an 8.84 ERA and 1.78 WHIP over 19.1 innings at Triple-A last season. If Kremer can continue to build on his production from spring training, it wouldn't be surprising to see him debut in the majors at some point in 2020.
