The Braves are expected to call up Wisler to make his major league debut Friday against the Mets, David O'Brien of the Atlanta Journal-Constitution reports. Friday's starter for Atlanta is still listed as "TBA," but the expectation is that manager Fredi Gonzalez will officially tab Wisler for the start after Thursday's game. The 22-year-old Wisler struggled in his last outing with Triple-A Gwinnett (seven runs in 3.2 innings), but he was outstanding in May and has been good with his control throughout the season (1.8 BB/9). It seems likely Wisler will be given a chance to hold down the rotation spot recently vacated by Mike Foltynewicz, who was optioned down after posting a 5.19 ERA in nine starts.
