Hernandez, known as Fausto Carmona when he won 19 games for the 2007 Cleveland Indians that reached the American League Championship Series, starts Saturday night's game for the Atlanta Braves at the St. Louis Cardinals.
The 36-year old Hernandez was about the only logical choice Atlanta (39-70) had for this one after right-hander Aaron Blair, who it had planned to promote from Triple-A Gwinnett to make the start, injured his knee Thursday and landed on the disabled list.
Their rotation already threadbare by other injuries and trades, the Braves turned to Hernandez, who is 4-6 with a 4.
