Frank Robinson caught Brendan Donnelly with pine tar on his glove, and Donnelly was properly ejected. Scioscia then goes over to tell off Frank Robinson, and the benches cleared. No punches were thrown, but, Jose Guillen needed to be restrained.

According to the AP story, Scioscia told Robinson he was going to check his pitchers:

Robinson, a former vice president of discipline for the major leagues, said Donnelly simply got caught cheating and Scioscia was "way off base."

"He took me by surprise when he came over to me and I took it as a threat," Robinson said. "He told me that he was going to have every one of my pitchers undressed when they came out there to the mound -- no matter who it was."

Said Scioscia: "I told Frank we were going to undress his pitchers when they were on the mound to see if they had any pine tar in their glove. He obviously wasn't happy. He was screaming. We weren't making a lunch date."

Mike, your pitcher got caught cheating. You should be upset with him. Instead, you fired up the Nationals and your good friend Jose Guillen hurt your cause with a home run. Your team was winning at that point, then lost the game. You should have chewed Donnelly out instead of making statements like this:

Scioscia acknowledged that the use of pine tar is against the rules, but said it is "used around baseball," doesn't alter the flight of the ball and usually isn't an issue.

Sure it doesn't. And I'm sure it keeps the ball sparkling clean, too. Robinson deserves an apology.

Update: A reader notes in the comments that Donnelly was caught with a spare ball in his pocket against the Red Sox. That seems more suspicious now.
