The Jayson Werth of 2013 is very different than the Jayson Werth of 2011. Back then, the Nationals' big-money free agent was slumping so hard that Duffy's Irish Pub began selling 16-ounce cans of PBR for whatever Werth's batting average was at the time.

I remember paying $2.11 at one point.

This summer, though, Werth has been on a tear, even when the team's other bats have fallen silent. His player-of-the-month performance in July included a .367 average, 7 homers, 22 RBI and a league-leading 1.072 OPS. He hasn't slowed down in August, batting .464 so far this month.

Werth's turnaround is being honored tonight at Duffy's during the Nationals' game against the Cubs. Anyone wearing Nationals gear will pay Werth's batting average – currently $3.30 – for any beer on the menu, whether you want a DC Brau, Coors Light or a pint of Guinness. A Werth home run means free shots of Irish whiskey for everyone in the bar.

As always, the game will be on every TV, the play-by-play will be at full volume and the bar will be full of Nats fans, who probably won't mind paying a little more than they did a few years ago.
