The visiting St. Louis Cardinals beat the Pittsburgh Pirates 2-1 on Monday behind a brilliant performance from rookie pitcher Michael Wacha to force a decisive fifth game in their National League Division Series.
Wacha, who came within one out of hurling a no-hitter in the regular season finale against the Washington Nationals, did not allow a hit to the Pirates until the eighth inning.
The only hit he yielded was a home run to Pirates slugging third baseman Pedro Alvarez that cut the deficit to 2-1 with one out in the bottom of the eighth. After a walk to Russell Martin, Carlos Martinez came on in relief to end the inning.
Trevor Rosenthal came on to pitch the ninth and issued a two-out walk to Neil Walker before retiring Andrew McCutchen on a pop out to second to close out the victory.
The 22-year-old Wacha struck out nine and walked two batters in his sensational postseason debut.
St. Louis, top seeds in the National League, scored their runs on a two-run homer by Matt Holliday in the sixth inning.
Game Five will be played in St. Louis on Wednesday.
