Baldwin vs. Krasinski in New Era campaign

Yankee fan Alec Baldwin and Red Sox supporter John Krasinski star in New Era Cap's season-long ad campaign focusing on MLB rivalries. The first commercial launches today during regional and national telecasts of the first Yankees-Red Sox game of the season.

According to the Sports Business Daily, this is a huge campaign for New Era since they generally employ MLB players or musicians in its marketing, as opposed to well known actors.

The spots will run during games throughout the season on ESPN, Fox, YES Network and NESN. Cable channels including Comedy Central, Adult Swim, Spike, FX, SportsNet N.Y. and others will also participate.
