Mark Langston, a Los Angeles Angels radio analyst and former four-time All-Star pitcher, was taken to a hospital Friday night in Houston because of a medical emergency.

The Los Angeles Daily News reported that the incident involving Langston, 59, occurred as he finished announcing the opening lineups in the series opener against the Astros at Minute Maid Park.

Angels TV broadcaster Victor Rojas shared an update on Langston from the hospital around midnight Friday and Astros broadcaster Robert Ford described the scene in the Angels' radio booth.

"Scary sight tonight watching things unfold in the booth two doors down from us. Currently sitting with Langer in ER and he’s doing well, sharing some laughs about his pizza intake in NYC this week," Rojas tweeted. "Keep Mark in your prayers as they continue to run through protocols."

The Angels said Saturday afternoon that Langston was resting comfortably and continuing to undergo tests.

"Sending love and prayers out to my longtime friend and someone whom I consider a brother, Mark Langston," Angels TV color analyst Mark Gubicza, who was teammates with Langston in 1997, tweeted Friday

Langston has been on the radio broadcast team since 2012. He pitched for the Seattle Mariners, Montreal Expos, Angels, San Diego Padres and Cleveland Indians, spending eight of his 16 seasons with the Angels.

He pitched a combined no-hitter with Angels reliever Mike Witt on April 11, 1990, led the American League in strikeouts in three of his first four seasons (while with Seattle) and was a seven-time Gold Glove award winner.
