Philadelphia Phillies pitcher Cole Hamels was hit with a five game suspension by Major League Baseball Monday for throwing at Washington Nationals rookie Bryce Harper.

Hamels was also fined an undisclosed amount.

The Phillies starter pegged Harper in the small of his back in the first inning Sunday night of Philadelphia’s 9-3 win.

Hamels later admitted in post-game interviews that the purpose of hitting Harper was his old-school way of welcoming the 19-year-old into the big leagues.

Unless appealed, Hamels is scheduled to begin serving his suspension Monday night when the Phillies host the New York Mets.
