ST. LOUIS (AP) — Michael Wacha will replace Justin Masterson in the St. Louis Cardinals’ rotation on Thursday and make his first start since mid-June. Manager Mike Matheny said Wacha, a breakout rookie star last year who was the NL championship series MVP, will be limited to around 60 pitches at Milwaukee. He’s 5-5 with a 2.79 ERA in 15 starts and has been on the 15-day disabled list with a right shoulder stress reaction.
