ST. LOUIS — So much for Michael Wacha being in the major leagues to stay.
The St. Louis Cardinals on Friday optioned the rookie right-hander to Class AAA Memphis to make room for Jake Westbrook (2-1, 1.62 ERA), the starting pitcher at 6:10 p.m. Friday in Miami.
Westbrook has been on the disabled list with elbow inflammation. He hasn't pitched since May 8, although he made recent two rehab starts at Memphis and at Class AA Springfield.
Wacha said May 29 when he was summoned to the big leagues that he was told he would be remaining in St. Louis.
Instead, the Cardinals' No. 1 pick in the 2012 draft made just three starts and was 1-0 with a 4.58 ERA. He allowed 17 hits in 17 2/3 innings, with four walks and 14 strikeouts.
Wacha's lone victory came Tuesday against the New York Mets at Citi Field, where he allowed two runs (earned) on five hits in six innings. The Cardinals won easily 9-2.
The Cardinals kept rookie left-hander Tyler Lyons on their roster instead of Wacha. Lyons (2-2, 3.51 ERA) will start the series finale against the Marlins at 12:10 p.m. Sunday.
