Giants pitcher Randy Johnson won his 300th game on Thursday, and recounted on his 21 seasons in the Major Leagues. San Francisco defeated Washington 5-1, as Johnson turned in a solid six-inning performance. "I think it kind of hit me when I walked on the field," Johnson said. "It's a long-range achievement. It's not a one-game or a one-year achievement, it's a career achievement. Who knows how many teammates I've had over my 21 years, but they had a great deal to do with my success. I'm going to think about this for a long time." Strangely enough, Johnson earned the win against his first team. He broke in with the Expos, who moved to Washington and were renamed earlier this decade. "I get more gratification out of that because of the way I'm doing it now than the way I did it 10 years ago," Johnson said.
