Irvin (1-0) earned the win Monday, allowing four hits and three walks over 6.1 scoreless innings in a 5-1 win over the Giants. He struck out five.
Irvin has now allowed just one run over 10.2 innings, getting his big-league career off to an impressive start after working his way up the ranks in Washington's farm system for three-plus seasons. However, this is a very small sample size, and fantasy managers would be best served tempering expectations until he proves capable of sustaining that caliber of performance over an extended period.
