On Thursday, the Braves called up Aaron Blair from AAA-Gwinnett, as a potential long relief arm should they need another in a close and/or extra-inning contest. Blair did not make his way into a game, and is now being sent back to Gwinnett, while Matt Wisler is getting his first call-up of the 2017 season.

Wisler has made 47 starts for the Braves since being acquired from the Padres prior to the 2015 season, posting a 4.88 / 4.88 / 4.87 pitching triple slash. He had pitched somewhat better in his three starts at Gwinnett this season (3.50 ERA, 4.33 FIP).
Blair had a rough 15 starts last season, ending the year with a 7.59 / 6.15 / 5.66 pitching triple slash across 70 innings. He will return to starting at Gwinnett, where he holds a 5.79 ERA and 4.52 FIP.
Wisler will presumably hang around until the Braves are able to recall another reliever, and then return to his starting rotation duties for the AAA club.
