ATLANTA -- Braves manager Fredi Gonzalez says right-hander Mike Foltynewicz will be called up from the minors to make his first career start Friday.
To make room for Foltynewicz on the roster, third baseman Chris Johnson will be placed on the 15-day disabled list with a broken left hand.
Foltynewicz, a top prospect acquired in the January trade that sent slugger Evan Gattis to Houston, went 0-3 with a 2.08 ERA in four starts at Triple-A Gwinnett this month. He struck out 30 in 21 2/3 innings.
In 16 relief appearances with the Astros last year, Foltynewicz went 0-1 with a 5.30 ERA. Houston drafted him in the first round of 2010.
Johnson was injured while sliding into second base in the fourth inning of Thursday's 5-1 loss to Cincinnati.
