Steve Aoki might be able to throw a cake with pinpoint accuracy -- but he sure as hell can't do the same with a baseball, 'cause he absolutely airmailed the ceremonial first pitch at the Red Sox game on Monday night ... and it was truly awful.
The DJ took the mound just minutes before Boston faced off with the Astros at Fenway Park ... and, given the results of the pitch, he's honestly probably wishing he hadn't.
Aoki warmed up his left arm, toed the rubber -- and then heaved a ball that went roughly 20 feet over his catcher's head. It was actually so bad, it rolled over the net behind home plate and fell into the crowd.
Video shot by people in the stadium shows fans were laughing at the pitch -- because it was seriously just that bad.
