Fresh from their best month, by wins, in five decades and rich with reinforcements due to this month’s expanded rosters, the Cardinals entered Saturday’s game against Cincinnati with a little bit of everything. Exiting, they just had a little bit. Cincinnati starter Luis Castillo shut out the Cardinals for 6 2/3 innings, held them to two hits, and sped the Reds to a 4-0 victory in front of an enthusiastic sellout crowd at Busch Stadium. Giveaway jerseys and a pennant race was the draw, but the 46,368 ticket buyers didn’t get a chance to see several of the players who hoisted the Cardinals back into the race.
