Major League Baseball has fined Washington Nationals general manager Mike Rizzo an undisclosed amount of money for comments he made about Phillies pitcher Cole Hamels, MLB.com reported.

Hamels hit Nationals rookie Bryce Harper with a pitch during Sunday's 9-3 loss to the Phillies, and Hamels later said he hit Harper on purpose.

Rizzo reportedly responded with some harsh words for Hamels, who was suspended five games for his actions.

"I've never seen a more classless, gutless [expletive] act in my 30 years in baseball," Rizzo said to the Washington Post. "Cole Hamels says he's old school? He's the polar opposite of old school. He's fake tough. He thinks he's going to intimidate us after hitting our 19-year-old rookie who's eight games into the big leagues? He doesn't know who he's dealing with."

On Tuesday, Rizzo declined to discuss Hamels or being fined. He praised Harper for the way he handled being hit, eventually scoring on a steal of home.

"[Harper] took it, went to first base, he showed good instincts of going from first to third, then putting it into play what Jayson, [third-base coach] Bo Porter and Bryce discussed in a pregame meeting -- the move that Cole had, and it worked perfectly. Bryce was terrific," Rizzo told MLB.com.

Harper did not criticize Hamels.

"It's totally fine. Cole is a great pitcher, he is an All-Star, and there is nothing I can say about it," Harper said, according to MLB.com. "It's in the past. Like I said before, he is an unbelievable pitcher. He knows what he is doing out there. I have a lot of respect for the guy. The Phillies' pitchers have been there, done that. One through five are pretty strong. I have a lot of respect for them."
