We all know about the Tiger Effect. And we all see the Rickie Fowler Effect with all those little kids dressed up like their favorite shaggy golfer.
Now, there's the Justin Rose Effect.
American Golf, a big British golf retailer, saw its sales and its web traffic spike in the wake of Rose's victory the U.S. Open.
In the week after the U.S. Open, the company registered a 16.4 percent increase in total sales across its store network, compared to the week after the 2012 tournament. And traffic to its website at www.americangolf.co.uk  jumped more than 50 percent over the same period.
''Justin's triumph in the U.S. Open is good for golf and good for business,'' American Golf CEO Kevin Styles told Golf Business News . ''It was a perfectly timed victory coming at the start of the peak golf season and will help to generate interest in the game.
''It's not only existing golfers that have been snapping up equipment,'' he added. ''We have had a lot of enquiries from people keen to take up the game for the first time.''
Rose was England's first U.S. Open winner in more than four decades and, not surprisingly, his equipment is now among the company's biggest sellers. Sales of TaylorMade's R1 drives were up 21 percrent for the week, while RBZ Stage 2 Tour fairway woods sales rose 38 percent. And those were small compared to the sales of ATV wedges, which were up a whopping 63 percent over the week before.
