Javier Baez has had enough of New York Mets fans booing him, and is taking matters into his own hands.

Since his trade to the Mets at the trade deadline, the infielder is hitting .207/.258/.414 with three homers and five RBIs in 16 games. Fans have responded to his struggles at the plate by booing the former Chicago Cub, and during the Mets' 9-4 victory on Sunday over the Nationals, Baez gave a thumbs-down sign to the crowd at Citi Field.
