Los Angeles Dodgers starting pitcher Walker Buehler was stripped of his guard at Santa Anita Park in Arcadia

ARCADIA, Calif. – Dodgers starting pitcher Walker Buehler was robbed of his expensive watch, ABC affiliate KABC learned Monday.

It's unclear when the incident occurred, but KABC learned that a crowd surrounded Buehler and his wife, McKenzie Marcinek, at Santa Anita Park in Arcadia, about 25 minutes northeast of downtown LA.

During the ambush, someone is said to have unbuttoned his shirt sleeve and taken his watch.

KABC reached out to Arcadia police Monday for more information but was referred to a detective who did not return our call.

Meanwhile, a Dodgers spokesperson did not comment on the incident.

Buehler prepares to take the mound in Game 3 of the National League Division Series on Tuesday in San Diego.

Buehler grew up in Lexington, Kentucky and is a lifelong horse racing fan.

In fact, Buehler owns a micro-share in the Thoroughbred American racehorse Authentic, trained by Bob Baffert, who won the 2020 Kentucky Derby.

Correction: An earlier version of this report said the incident occurred over the weekend. KABC is working to obtain more information.
