From the MiLB account of Saturday night's Gwinnett game:
Things went wrong from the very first inning for the G-Braves, as Atlanta Braves' right-hander John Gant, making a rehab start, gave up a lead-off home run to Johnny Field. Gant then issued walks to Jake Goebbert, Curt Casali and Casey Gillaspie to load the bases with one out. The count went to 3-2 to the next batter, Dayron Varona, but Gant called time and went to the back of the mound where he became ill and had to be pulled from the game.
