The game has been filled with highlight plays, but the biggest of all came when Jackson Glenn hit his 2-run dinger to put the Patriots up early in the 3rd inning ... with the fan snagging the ball in the left-field stands!!
Of course, the folks at ESPN tracked the fan down and got the footage he captured ... and it's pretty wild!!
The fan got a ton of praise from the guys in the booth, too ... saying, "That's just pre-determined knowledge of what's about to happen in the game."
"It's a smart baseball fan there!"
The kid's a natural with the glove ... so we gotta assume he's a baseball superstar for his local club.
