With the Cardinals' bench short because of infielder-outfielder Scott Spiezio's infected left index finger, left fielder Chris Duncan, a left-handed batter, was allowed to bat against Reds lefty-hander John Coutlangus with two on, no outs and the Cardinals down a run in the eighth.
The win was Percival's first in the big leagues since 2005, when he was with Detroit. He had retired with an arm injury before making a comeback this spring.
"Kind of a dream come true," said manager Tony La Russa. "That's movie material."
CARDINALS 4, REDS 2: Right-hander Jason Isringhausen, featuring a sharp curveball, pitched out of a two-on jam in the ninth inning to gain his first save in 23 days. RF Juan Encarnacion knocked in one run with a double and another with a single and C Yadier Molina contributed two singles in his first game in a month -- he had been out with a fractured left wrist.

--RHP Brad Thompson, who had flown ahead to Cincinnati before the Cardinals' game in New York was rained out on Thursday, got the start Friday. Manager Tony La Russa and pitching coach Dave Duncan originally were to have RHP Adam Wainwright, rained out in New York, start in Cincinnati, but the club was delayed in leaving New York and La Russa decided to stay with Thompson. Wainwright has been pushed back to Saturday night, and recently acquired LHP Mike Maroth will pitch Sunday.

--3B Scott Rolen's hitting streak ended at eight although Rolen did walk and score a run.
