Suppan, who will start Wednesday in the finale of the three-game series, spent parts of four seasons with the Cardinals. He helped them to the 2006 World Series championship with a 12-7 regular season record and a 1-1 mark in postseason play. Suppan was named MVP of the NLCS, allowing one earned run in 15 innings against the Mets.
The St. Louis fans always appreciated Suppan's strong work ethic.
"I had a good experience here," Suppan said. "To win a World Series was incredible. I never thought I'd be in that situation."
Suppan also won 16 games in 2004 and 2005 with the Cardinals.
"It's always fun to come back," he said.
Suppan played with Milwaukee in 2007 but will never forget his first game back in St. Louis. He was given his World Series ring in a ceremony at home plate. St. Louis coaches and players came out and joined him as he was awarded his ring. The crowd gave him a lengthy standing ovation.
"It was very special," Suppan said. "These fans love baseball and they appreciate hard work and dedication."
Suppan, 37, signed with San Diego as a Minor League free agent on Feb. 8. He is 2-0 with a 2.42 ERA in four starts as a visitor at Busch Stadium. His teams have won all four of those games.
The Oklahoma City native carries a 2-2 mark with a 3.00 ERA into his fifth start of the season.
