"The Big Unit reached a big milestone - 300 wins.

Randy Johnson looked like the sure Hall of Famer he'll one day become. Relying on a fastball 10 mph slower than his prime, the San Francisco Giants left-hander secured his historic moment with a 5-1 victory over the Washington Nationals on Thursday.

Johnson opened with three perfect innings before dinged for a walk in the fourth, a hit in the fifth and an unearned run in the sixth. Fans clearly were behind Johnson, moaning twice over questionable ball calls that would have been strikeouts while cheering Johnson after chasing down a grounder while tripping.

Johnson became baseball's 24th and perhaps last 300-game winner for many years. It was a gem - permitting only two hits while throwing 50 strikes in 78 pitches over six innings. Only two fly balls, a single and one sharply-hit double left the infield despite most pitches reaching only the mid-80s. Johnson struck out Austin Kearns with a 92 mph fastball, but it wasn't the overpowering stuff of Johnson's past.

"I only have 211 more to catch Cy Young," joked Johnson of the career wins leader."
