Former Major League infielder Jose Castillo, 37, was also killed in the crash. The vehicle's driver lost control, and the auto hit a rock, causing it to overturn, the report says.
Venezuelan newspapers El Emergente and Meridiano reported on the accident, with the Houston Chronicle's sportswriter Chandler Rome, confirming the news. They were reportedly killed on impact. Major League Baseball also confirmed the news in a statement on social media.More news: Prince William and Kate bring gifts to RAF base in Cyprus
Major League Baseball tweeted late Thursday the 33-year-old Valbuena and 37-year-old Castillo died.
Valbuena received plenty of playing time during the final stages of the Cubs' rebuilding before he was traded with pitcher Dan Straily to the Astros for switch-hitter Dexter Fowler prior to the 2015 season. Valbuena suited up for Los Angeles as recently as the 2018 season, but the Angels released him in August. He collected four hits in seven at-bats (.571 average) while hitting a home run and driving in three runs.
Castillo debuted in Major League Baseball in 2004 and played four seasons for the Pittsburgh Pirates. He hit nine home runs and drove in 33 runs for the Halos in 96 games in 2018.
