Atlanta is slumping but most of that damage done away; the team is 24-14 at home. The Braves are 22-14 overall vs. lefties and rank 12th in OPS against them, while the Cards are 12-8 vs. southpaws and have the No. 16 OPS. Relevant because both start one. St. Louis' Matt Liberatore has been raked this month to a 10.34 ERA in four starts. Counterpart Martin Perez (6-4, 3.00 ERA) continues to deliver at age 35. At home, his ERA is 1.64 and opponents' BA .177.
