Cardinals pitcher Michael Wacha will not make his scheduled start Tuesday against the Pirates, as the game has been postponed due to rain, Jenifer Langosch of MLB.com reports.
The game has been rescheduled as part of a doubleheader Wednesday. Look for Wacha to simply move back to start one game of the twin bill, as he attempts to go 3-0 against the Pirates during the regular season. He's allowed just four earned runs in 18.2 innings against Pittsburgh so far this year.
