The Braves have exchanged one left-handed reliever for another off the 60-day injured list. The club announced that Grant Dayton has been activated, while A.J. Minter’s season was placed on the IL due to inflammation in his throwing shoulder, which will end his season.
After missing all of 2018 due to Tommy John surgery, Dayton returned to a big league mound for 8 1/3 innings over 10 games for Atlanta this season, posting a 2.16 ERA and 11.9 K/9 over his brief stint. A fractured big toe sent him to the injured list on July 12, however, so Dayton will return after exactly a two-month absence. Over 58 1/3 career innings with the Braves and Dodgers, Dayton has dominated left-handed batters (holding them to a .574 OPS) and also performed quite well against righty batters (.711 OPS) en route to a 3.24 ERA, 3.33 K/BB rate, and 10.8 K/9.
As a whole, Atlanta’s bullpen has middle-of-the-pack type of numbers against left-handed hitters this season, so Dayton could provide more of an overall boost than Minter, who has struggled through a very rough campaign. After breaking out and even stepping into a part-time closer role for the Braves in 2018, Minter has a 7.06 ERA over 29 1/3 innings this year, due in large part to major control issues. He has issued 23 walks (18 international) over those 29 1/3 IP, making for a 7.1 BB/9 that more than doubles his previous highs in that category at either the MLB or minor league levels.
