LOS ANGELES — Former major league pitcher Mike Bolsinger sued the Houston Astros on Monday, claiming their sign-stealing scheme contributed to a poor relief appearance in August 2017 that essentially ended his big league career.

Bolsinger’s suit in Los Angeles County Superior Court seeks unspecified damages for interfering with and harming his career. He’s also asking that the Astros forfeit their nearly $30 million in postseason shares from their 2017 World Series title, with the money going to children’s charities in Los Angeles and a fund for needy retired players.

According to the suit, Bolsinger, then a reliever with the Toronto Blue Jays, was put into a game at Houston on Aug. 4, 2017, and allowed four runs, four hits and three walks in one-third of an inning in a 16-7 loss. The suit said the right-hander “was immediately terminated and cut from the team, never to return to Major League Baseball again.”

He was demoted to Triple-A and hasn’t pitched in the major leagues since.
