'Big Unit' wins 300th

Randy Johnson became the 24th pitcher in major league history to win 300 games today when he beat the Washington Nationals.

The Nationals were a fitting opponent for Johnson, who started his professional career with that franchise when it was known as the Montreal Expos.

Johnson is the second-oldest pitcher to reach the 300 mark -- behind only Phil Niekro, who achieved the feat when he was 46 years and 188 days old on Oct. 6, 1985. Johnson is 45 years and 267 days old.

Johnson pitched 6 innings, giving up just 2 hits, 2 walks, no runs, and struck out 2. The Giants won the game 5-1.

Johnson also became only the 5th pitcher in history to do it on his first attempt.
