Grant Dayton doesn’t have enough career major league innings to draw significant conclusions from. At age 32, that fact may be the significant conclusion. However, what little we have to go on is promising.
Dayton was 28 before he hit the majors in 2016. The left handed reliever combined for 50 innings in 2 seasons with the Dodgers before undergoing Tommy John surgery. The Braves claimed him off waivers in November of 2017, and he missed the entire 2018 season recovering from that surgery.
Grant made his Atlanta debut in late April, and bounced back and forth between Atlanta and Gwinnett before a broken toe in July cost him 2 months. His final contribution consisted of just 12 major league innings. He struck out 14 batters in those 12 innings, but also allowed 4 home runs.
At Gwinnett, Dayton struck out 41 batters in 26 2/3 innings, with a 3.04 ERA and 0.900 WHIP. In his major league career, he has struck out 73 batters in 62 innings. It’s only 142 and 112 plate appearances respectively, but Grant has been pretty effective against both right handed and left handed batters. He has a career .220/.284/.433 BA/OBP/SLG line against righties, and against lefties it is .170/.250/.340.
Dayton’s arbitration eligible for the 2020 season at an estimated $800K via MLBTR and could be useful in a certain role if he can stay healthy for a full season.
