Underneath the white caddy uniform, Joe LaCava was repping the Giants.
And also helping Tiger Woods win his 15th major -- the golfer's first since 2008 -- at The Master on Sunday.
As Woods charged down the back nine and LaCava next to him every step of the way, the caddy donned a Saquon Barkley jersey that was visible at various points during the telecast.
LaCava is a New York sports fan from Connecticut. Last year, he sported a Rangers jersey under his uniform.
