The Griffeys -- 20-year-old Ken Jr. and his dad, Ken, 40 -- made major league history and magic moments last night in Seattle, leading the Mariners over the Kansas City Royals, 5-2.

The Griffeys were the first father and son to play together in the big leagues, and they didn't disappoint. With one out in the first inning, Griffey Sr. singled and Griffey Jr. followed with another single, and both wound up scoring.

In the sixth inning, the elder Griffey played the ball off the bullpen wall in left field and threw out Bo Jackson trying to stretch a single into a double.

Griffey Jr. reacted emotionally to his dad's play. He hunched down on his hands and knees in center field and broke into a beaming smile. Griffey got a standing ovation from the crowd of 27,166 after the play. Winning pitcher Randy Johnson (13-8) and other Mariners congratulated him.

The Mariners, who signed Griffey on Wednesday after he had been waived by Cincinnati, scored their three runs in the opening inning off Storm Davis (7-10) on four singles.

After the Griffeys singled -- the ball was taken out of play following each hit -- Alvin Davis hit an RBI single. Griffey Jr. scored on a wild pitch and Edgar Martinez hit a run-scoring single. Both Griffeys finished one for four.

Before the game, the fans watched on the video scoreboard as Craig Griffey, 19, a cornerback at Ohio State, talked to his brother -- who was an AL starter in July's All-Star Game -- and former all-star father.

"The first time up, I was really nervous," Griffey Sr. said. "It was like being a rookie all over again. There wasn't any pressure, just butterflies."

"I wanted to cry," Griffey Jr. said. "It was his day. . . . It seemed like a father-son game . . . like we were out in the backyard playing catch."

Even Jackson was caught up in the emotion of the night. "I didn't expect . . . to have that old guy throw me out," he said, smiling. "I'd have been mad if anyone else had . . . but it was a piece of history. Those Griffeys were messing with me."
