He played five seasons in Major League Baseball (MLB) from 2000 to 2008 for the Minnesota Twins, Texas Rangers, Colorado Rockies, Baltimore Orioles, and Los Angeles Dodgers.

[1] Ardoin attended Sacred Heart High School in Ville Platte, Louisiana, where he played for Scott Carter and helped lead the Trojans to a state title in 1992.

Ardoin was heavily recruited as a senior by the Seattle Mariners and the Cincinnati Reds, but chose to play JUCO ball at Texarkana Junior College, and then attended McNeese State University.

He made his way up through the A's farm system from 1996 to 2000, playing for the Modesto A's, Visalia Oaks, Huntsville Stars, Vancouver Canadians, and Sacramento River Cats.

After only three games with the Buzz, Ardoin made his major league debut on August 2, 2000 against the Baltimore Orioles, going hitless in two at-bats with three walks and a run scored.

Ardoin strained his left knee while tagging out Los Angeles Dodgers outfielder José Cruz Jr. on a play at home plate, and he was placed on the disabled list on May 27.

In the offseason, the Dodgers signed three-time Gold Glove winner Brad Ausmus to be the new backup catcher, and transferred Ardoin to the AAA Albuquerque Isotopes where he was scheduled to back up prospect A. J. Ellis.

Ardoin's son, Silas, graduated high school in 2019 and went on to catch for the University of Texas Longhorns baseball team, advancing to the College World Series in 2021 and 2022.
