On September 24, which was Yom Kippur, Youkilis appeared in the dugout in uniform, but declined to participate in the game out of deference to the religious holiday. Youkilis was named the club's Rookie of the Year by the Boston chapter of the Baseball Writers' Association of America. For the season, in 44 games, he saw an average of 4.67 pitches per plate appearance, first among major leaguers with at least 90 plate appearances. As Youkilis observed, "Fighting off pitches, fouling off pitches, laying off pitches, making it so the opposing pitcher can't breathe; that's my job." He was on the roster for the Red Sox for the 2004 American League Division Series (ALDS), making his sole appearance in Game 2 against the Anaheim Angels. "It's been an unbelievable ride", Youkilis said. "It's a great first year, a year you probably can't top. Hopefully, it ends like a Cinderella story." He was removed from the roster for the next round, the American League Championship Series (ALCS), and was on the roster but did not play in the World Series.
