Year of the Grand Slam?

I missed the game today, but here's a quick recap of what happened:

Brett Gardner hit a grand slam in the Yankees 11-run third inning offensive outburst to lead the Bronx Bombers to an 11-3 win over the Toronto Blue Jays.

Andy Pettitte earned his tenth win as he went six innings allowing three runs on five hits while striking out four.

Alex Rodriguez had an impressive day as well knocking in four runs.

And is it me, or is this the year of the grand slam? It was the eighth (yes EIGHTH!) grand slam of the season for the Yankees. While last year was the year of the walkoff, this year may just be the year of the grand slam.
