Red Sox Nation is in mourning again.

Dave McCarty, a retired first baseman and outfielder who was part of the Major League baseball team during their historic 2004 World Series victory, has died. He was 54.

The Boston Red Sox announced in a press release that the athlete passed "due to a cardiac event" in Oakland, Calif. April 20. "Our hearts are heavy with the passing of Dave McCarty," the team said on X, formerly Twitter. "Playing 3 seasons with the Red Sox, he will forever be a part of the curse-breaking 2004 World Series championship team. We send our love to his wife, Monica, and their children, Reid and Maxine."

McCarty died one month after he joined several of his past teammates at the Red Sox's home of Fenway Park for a 20-year reunion and tribute ceremony for the 2004 World Series team, held before the 2024 Opening Day game.

Also in attendance at the April 9 event: Brianna Grace Wakefield and Trevor Wakefield, who were invited to help honor their father Tim Wakefield, who had pitched in the championship game and died of brain cancer at age 57 in October, and their mom Stacy Wakefield, who passed away in February.

McCarty, a native of Houston, Texas, played in the MLB between 1993 and 2005 and was first drafted into the league by the Minnesota Twins. He was a member of the team for two years and later played for the San Francisco Giants, the Seattle Mariners, the Kansas City Royals, the Tampa Bay Rays and the Oakland A's before joining the Red Sox in 2003. He retired from professional baseball in 2005 and later worked as a Red Sox baseball analyst for NESN until 2008.
