Live feed shown in Arizona’s dugout

A monitor in Arizona’s dugout at Oracle Park in San Francisco showed a live television feed during the first inning of Monday night’s game between the Diamondbacks and Giants, and Diamondbacks manager Torey Lovullo said a day later that he quickly informed umpires about the technical snafu.

Arizona lost 6-1 on Monday night. Lovullo said Tuesday he alerted crew chief Dan Bellino about the live feed to make sure there was no misunderstanding about possible cheating.

Lovullo also told Bellino he had instructed his players not to look at the two monitors in one corner of the dugout. The two screens typically show feeds of the two clubs’ bullpens, but something was awry with the control center for one of the monitors on Arizona’s side.

“We have zero control over them. Zero,” Lovullo said. “It’s all in-house, upstairs, the play-by-play.”
