Tom Brady reacts to Rob Gronkowski's first pitch before Red Sox game - ESPN

Rob Gronkowski's first pitch before the Boston Red Sox game Monday might have been better suited in the end zone.

Wearing a Red Sox jersey with «Gronk» on the back, the former New England Patriots star had a short windup before spiking the baseball into the mound and raising his right fist in the air.

It's a similar spike to what Gronkowski used to do after scoring a touchdown in the NFL. His 93 receiving touchdowns are the third most by a tight end.

The first pitch caught the attention of Tom Brady, who played with Gronkowski in New England and with the Tampa Bay Buccaneers. The two won four Super Bowls together with Brady and Gronkowski connecting for 105 touchdowns (in the regular season and playoffs), according to ESPN Stats & Information.

Brady had a simple response at the sight of a trademark Gronkowski spike with a comment on Instagram.
