Game 2 of the World Series hit another home run for Fox.

The Yankees 3-1 win over Philly Thursday night snared nearly 19 million viewers — the most-watched Game 2 since 2004 (Red Sox-Cards).

It also averaged nearly 3 million viewers on Ch. 5, easily crushing the local competition.

The solid Game 2 numbers led Fox to an easy prime-time victory over established shows including “Grey’s Anatomy” — which still managed a solid 13.4 million viewers.
