As of Saturday, the only certainly is that Kyle Lohse will start Tuesday's series opener. St. Louis has several starting options for Wednesday and Thursday, though manager Mike Matheny said the club will likely wait until Monday to solidify its plans.
Monday's scheduled off-day provides added flexibility should the Cardinals wish to drastically alter their rotation. Both Joe Kelly and Lance Lynn would be ready to start Wednesday on a normal rest.
The one who doesn't would then join Jaime Garcia and Chris Carpenter as options for Thursday. If Garcia struggles on the road again Saturday night, the Cardinals may want to give that Thursday home start to the left-hander. That's because the six games that follow will all be played on the road.
Jake Westbrook (right oblique strain) will not be in the mix for a start in the series.
