Former Major League Baseball star Mark Teixeira has declared his candidacy for Texas’s 21st Congressional District, positioning himself as a Republican candidate with a focus on conservative principles. The announcement came via social media, where Teixeira emphasized his lifelong commitment to conservatism and pledged to advance policies aimed at strengthening Texas and the United States.

Teixeira, who played first base for four MLB teams—including the Texas Rangers—over 13 seasons, highlighted his plans to support President Donald Trump’s agenda. The seat he is contesting is currently held by Rep. Chip Roy (R-Texas), a member of the House Freedom Caucus, who recently announced his bid for state attorney general.

The district, considered a Republican stronghold, saw Roy win re-election in 2023 with a 26% margin. Teixeira’s high-profile background as a professional athlete and his ties to Texas, where he relocated in 2021, are expected to aid his fundraising efforts. His campaign also aligns with a broader trend of former athletes backing Trump, including Hall of Fame closer Mariano Rivera and All-Star Johnny Damon, both of whom have publicly supported the former president.

Teixeira’s entry into politics underscores the growing influence of sports figures in U.S. electoral races, leveraging their public recognition to pursue legislative careers.
