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.
