Randy Johnson earned his 299th victory with six very impressive innings, giving up three hits and one run in the Giants? 6-3 home win over the Braves on Wednesday night, as reported by the Associated Press.

The five-time Cy Young Award winner struck out five to run his career total to 4,843, second-most in MLB history.

Johnson likely will get his first chance to become the 24th major leaguer with 300 victories next Wednesday at Washington.
