He eventually earned a call-up on September 7, and recorded the first hit of his major league career in the second inning against the Chicago Cubs. Taguchi became the first Japanese-born player in Cardinal history. He originally requested to wear the number 6, but he couldn't because it was retired for Stan Musial, nor could he turn 6 upside down because 9 is retired for Enos Slaughter. He could not wear the number he had at the Olympics because 1 was retired for Ozzie Smith. He was also unable to double 6 as Rick Ankiel was on the roster that year. Finally, he decided to wear 99. on May 30,. Taguchi got another brief call-up in, then got more playing time with the Cardinals in, appearing in 109 games.

He responded with his best season, batting.288 in 396 at-bats with eight home runs and fifty-three RBI, and contributing with his stellar defense at all three outfield positions as the Cardinals won 100 games and had the best record in the National League. Cardinal radio announcer Mike Shannon took to calling Taguchi "the So-man" and praising his hard work and extreme personal courtesy. By habit Taguchi would even give a little bow to the umpire whenever he stepped up to the plate.

In, Taguchi's playing time declined somewhat, his at-bat total falling to 316 from 396 the year before. However, Taguchi would make the playoff roster for the Cardinals for the third year in a row, and have a heroic postseason moment: on October 13, 2006, he hit the go-ahead home run off Billy Wagner in the top of the 9th inning of Game 2 of the NLCS. The home run gave the Cardinals a 7–6 lead in a game they would win 9-6. Taguchi played in four of five games of the 2006 World Series for the Cardinals, hitting.182, and won a World Series ring as the Cardinals defeated the Detroit Tigers four games to one. Taguchi agreed to a one-year deal worth $925,000 with the St. Louis Cardinals for the season. Taguchi returned to the Cardinals in 2007 and had another solid season, batting.290 as a part-time player, with 307 at-bats in 130 games. He was one of manager Tony La Russa's most valuable pinch-hitters; of 46 games in 2007 where he's shown to have had just 1 AB, Taguchi picked up 15 hits. Taguchi played 617 innings in the field, with 41 starts in center and 21 starts in left. Taguchi played sparingly in right field and part of a game at 2B.

Taguchi's numbers fell off sharply, his batting average dropping from.290 in 2007 to.220 in 2008, and he got only 91 at-bats for the whole season. However, he was included on Philadelphia's postseason roster and won his second championship ring when the Phillies won the 2008 World Series.
