LOS ANGELES -- Jason Romano is aware of recent history, so the 23-year-old rookie didn't hesitate when he saw a fan on the field at Dodger Stadium approaching teammate Brian Jordan.

Romano tackled him.

"You have to be thinking of the way things have been the last couple of years," Romano said. "Knowing the way the world is today, you have to do something."

And so Romano did do something with two outs in the top of the ninth inning Wednesday night before the fan, identified as 26-year-old Oscar Villanueva, was taken from the field by stadium security.

The game, won by the Dodgers 3-2 over the Colorado Rockies, was delayed only briefly.

Dodgers spokesman John Olguin said Thursday that Villanueva was charged with trespassing.

Kansas City Royals first baseman Tom Gamboa was attacked by a father and son during a game at the Chicago White Sox last September, and umpire Laz Diaz was accosted by a fan at the same ballpark last month.

Villanueva came onto the field during a break in the action, while manager Jim Tracy and others were checking on reliever Eric Gagne, who had deflected pinch hitter Greg Norton's infield single with his pitching hand.

"The fan had his hand out, like he wanted to meet me," said Jordan, who had moved from center field to left in the eighth inning, when Romano was inserted in center. "He tried to fake security out a little, then came my bodyguard from center field. It was impressive. I saw the fan run and fake, then Romano just blasted him.

"I knew he didn't mean any harm, but I knew he was going to pay for it somehow."

Said Romano: "I hit him shoulder-to-shoulder, like a football tackle. He came after BJ to shake his hand or something. I was in a dead sprint -- saw him put his hands up, and I hit him."

The matter was still a subject of conversation before the Dodgers and Rockies completed their three-game series with a day game Thursday.

"That's no place for people to be," Tracy said. "You don't belong out there. If I was sitting near someone who did that, I'd tell on them, because that's not right."
