The Cardinals are only halfway home to their fourth National League championship in the last 10 seasons but at least they know they will play at Busch Stadium again this year. Michael Wacha the brilliant Cardinals righthanded rookie didn’t hold the opposition to one hit as he had in his past two starts. But he didn’t allow any runs either in 6 2/3 innings today at Busch Stadium before turning the ball over mostly to other rookies as the Cardinals edged the Los Angeles Dodgers 1-0 to take a 2-0 lead in the best-of-seven league championship series with the next three games if all are necessary to be played in Los Angeles on Monday through Wednesday. The next time the Cardinals play at Busch they either still will be trying to win this series or they will be performing in the World Series. For the second game in succession a Los Angeles ace pitched about as well as he could. But still not good enough to win. Today lefthander Clayton Kershaw held the Cardinals to two hits in six innings. But one of the hits was a leadoff double by in the fifth by David Freese who went to third on a passed ball by catcher A.J. Ellis. After Matt Adams fanned and a suicide squeeze attempt was fouled off by Jon Jay the Cardinals’ center fielder lofted a short fly to left. Freese not known for his speed scored easily as weak-armed Carl Crawford’s throw was well off line. Wacha’s best pitching came in the sixth after a throwing error by second baseman Matt Carpenter gave the Dodgers runners at second and third with no out. Wacha induced a popup by Mark Ellis. After an intentional walk to Adrian Gonzalez Wacha struck out Yasiel Puig for the third time and Juan Uribe for the second time. Wacha left after eight strikeouts and 112 pitches and rookie Kevin Siegrist got the last out of the seventh after throwing two wild pitches. Oldster Randy Choate retiring lefthanded-hitting Crawford for the second day in a row recorded the first out of the eighth and then rookie Carlos Martinez fanned Mark Ellis and Gonzalez both of whom had no chance to end the eighth. Trevor Rosenthal with similar dominance posted the save with Puig absorbing his fourth straight strikeout to start the ninth. Puig has struck out six times in 10 hitless at-bats in the series and hasn’t hit a ball out of the infield. Rosenthal throwing little else but gas then fanned Uribe (his third whiff of the day) and pinch hitter Andre Ethier. The Dodgers who haven’t scored in the last 19 innings of this series were weakened when center fielder Ethier (ankle) and shortstop Hanley Ramiez (ribs) both couldn’t play although Ethier did make the last out. And now they'll have to face Cardinals ace Adam Wainwright on Monday night.
