The Cardinals suffered their third sweep of the season by losing to the Astros 6-4 on Wednesday night. Interestingly enough, two of those sweeps came from Houston. St. Louis took the lead in the fourth inning when Roger Cedeno doubled in So Taguchi, then scored on a throwing error by Jose Vizcaino to give the Cardinals a 2-1 lead. Mike Ensberg’s two-run homer in the bottom half of the inning of Jeff Suppan made it 3-2, Houston and Jeff Bagwell’s RBI double in the fifth made it 4-2. In the sixth inning Scott Rolen hit his 34th homer of the year to tie it up at 4-4. RBI’s from Bagwell and Lance Burkman off Suppan made it 6-4 Houston. The put the Astros a half-game in front of the Giants and Cubs in the National League Wild Card spot… Reliever Steve Kline pitched 2/3 of an inning in the eighth and faced three batters, walking one. He hasn’t thrown since Aug. 27 with a groin injury and then a torn tendon in his finger.
