ST. LOUIS (AP) — For four straight starts, Michael Wacha has been all but untouchable and appeared totally oblivious to the stakes. The St. Louis Cardinals need one more just like that from the pressure-proof rookie to get to the World Series for the second time in three years.

Wacha outpitched NL Cy Young front-runner Clayton Kershaw in Game 1 and the Cardinals won 1-0 on an unearned run. They’re matched again in Game 6 tonight (Friday night), the precocious right-hander and the lefty who’d be at the top of anyone’s list to work a must-win. The Dodgers brought the series back to St. Louis by muscling up on offense. Adrian Gonzalez hit two of their four homers in a 6-4 Game 5 victory Wednesday.

Runs should be a lot harder to come by in Game 6.
