CINCINNATI (AP) - Skip Schumaker hit his first career grand slam during St. Louis Cardinals' biggest inning of the season, supplying more than enough runs for right-hander Chris Carpenter to beat the Cincinnati Reds for the ninth time in a row, 7-3 on Monday night.
The Cardinals provided a lopsided start to their showdown for first place in the NL Central, trimming Cincinnati's lead to one game.
St. Louis sent 12 batters to the plate for seven runs in the fourth, giving rookie Mike Leake (7-4) his worst moments in the majors. Schumaker's grand slam - only his 19th career homer - made it 6-0.
Carpenter (13-3) has won his last nine starts against the Reds, a streak that started in 2006. He gave up five hits and a pair of runs in seven innings.
