ATLANTA -- With the St. Louis Cardinals not beginning their National League Division Series until Friday, the rainout against the Atlanta Braves on Saturday night won't impact the team's pitching plans.

Right-hander John Lackey, who will start Game 1 of Sunday's makeup doubleheader, would still have four days of rest before Game 1 in St. Louis against the winner of the NL wild-card game.

The Braves waited out a delay of nearly two hours before declaring the postponement and scheduling two games for the final day of the regular season, with the first starting at 1:10 p.m. ET.

The Cardinals, who clinched the NL Central on Wednesday and hold the best record in the majors at 100-60, have not announced their postseason pitching plans. Carlos Martinez's shoulder injury and Michael Wacha's recent struggles, though, make Lackey the logical choice to head the rotation.

Lackey is 13-9 with a 2.69 ERA after going 2-1 with a 1.78 ERA in five September starts, working at least seven innings each time. The 36-year-old veteran has pitched a team-high 214 innings and leads with 171 strikeouts.

Braves right-hander Shelby Miller will try to end his 24-start winless streak when he faces Lackey in the doubleheader opener. The former Cardinal has lost 16 consecutive decisions in falling to 5-17 despite a 3.15 ERA.

Cardinals rookie outfielder/first baseman Stephen Piscotty will play in at least one of Sunday's games after passing his final concussion test. He has been sidelined since a scary outfield collision in Pittsburgh on Monday.

Piscotty, who was hospitalized day while tests were performed, has played a key role for the Cardinals since being promoted from Triple-A Memphis, batting .310 with seven homers and 39 RBIs in 62 games.

"I know that we'd like to get him back out there," St. Louis manager Mike Matheny said.
