He was named Pioneer League Player of the Week for July 12–18 and in his first professional season he made the jump from Rookie-league to Double-A.

With the Billings Mustangs, Clinton LumberKings and Chattanooga Lookouts Broussard combined to hit .332 with 24 home runs and 75 RBIs.

He began his professional career by reaching base safely in each of his first 44 games, three short of the all-time record held by Alvin Davis.

Broussard split the 2001 season between the Class-A Mudville Nine and Double-A Chattanooga, combining to hit .303 with 28 home runs and 90 RBIs.

Among all Reds minor leaguers he ranked tied for second in home runs, fourth in RBIs and fifth in hitting.

He was named Southern League Batter of the Week three times and on the year appeared in 123 games at first base and three in the outfield.

He was a member of Team USA that won a silver medal in the 2001 Baseball World Cup in Taiwan along with Josh Bard and Jason Stanford.

He began the 2002 season with the Triple-A Louisville Bats, hitting .295 in April with four home runs and 18 RBIs in 24 games.

He was named the Cincinnati organization's best hitter for average and sixth-best prospect by Baseball America entering the 2002 season.

After being acquired he was assigned to the Triple-A Buffalo Bisons where he appeared in 14 games before being recalled to Cleveland on June 22 when Todd Dunwoody was placed on the disabled list.

He made his Major League debut that night in a pinch-hitting appearance against the Montreal Expos and made his first start in left field on June 23 at Montreal, notching his first hit in the second inning off Tony Armas Jr. Broussard hit his first home run on June 26 at Boston off Pedro Martínez.

He was recalled for second time after the conclusion of the Triple-A playoffs and appeared in 8 games in September, going 5 for 18 with a home run and two RBIa.

Broussard spent most of the 2003 season in the Major Leagues with Cleveland and teamed with Travis Hafner in the second half to solidify the first base position.

Broussard also became just the fourth player in Major League baseball history and the first since Darryl Strawberry in 1998 to hit two pinch-hit grand slams in the same season.

On the year he hit three grand slams which equaled the AL lead with Hank Blalock & Rubén Sierra.

Broussard went on to have a successful stint with the Indians, and was traded to the Seattle Mariners on July 26, 2006, for outfielder Shin-Soo Choo and a player to be named later (who turned out to be minor leaguer Shawn Nottingham).

On May 5, 2007, he hit a home run in the 8th inning against Chien-Ming Wang, to break up a perfect game with only five outs to go.

Broussard is one of only five Major League Baseball players to hit two pinch-hit grand slams in the same season.

The others are Davey Johnson of the Philadelphia Phillies, Mike Ivie of the San Francisco Giants, Darryl Strawberry of the New York Yankees, and Brooks Conrad of the Atlanta Braves.

Other big league players on the album included Jimmy Rollins, Sean Casey and Ozzie Smith.

Broussard said this about changing his career path to a professional musician: I guess we all have that competitive fire inside.
