CARLSBAD, Calif.--(BUSINESS WIRE)--April 7, 2003

Callaway Golf (NYSE: ELY) Staff Professional Annika Sorenstam earned her first victory of the season yesterday, posting a wire-to-wire win at the Office Depot Championship. Sorenstam's four-stroke triumph at El Caballero Country Club near Los Angeles was one of two victories yesterday for golfers using Callaway Golf's Great Big Bertha(R) II Titanium Drivers across the world's major professional tours. It was a winning weekend across the board for Callaway Golf, as the Company's equipment was used by the winner on each of the three major professional tours that were active yesterday -- the PGA, LPGA and Japan Golf tours.

Sorenstam's victory at the Office Depot Championship is the first tour win for the new Odyssey(R) DFX(TM) 2-Ball Putter. Sorenstam used her new putter to roll in birdie putts on the last two holes and punctuate her 43rd career LPGA Tour victory, which is the fourth worldwide tour victory for Odyssey 2-Ball Putters this year. Three golfers used Odyssey 2-Ball Putters to earn top-10 finishes at the Office Depot Championship.

In all, Sorenstam used 11 Callaway Golf clubs at the Office Depot Championship, including her Great Big Bertha II Pro Series Titanium Driver and the new Steelhead(TM) X-16(TM) Irons, along with the HX(R) Red golf ball. Sorenstam also became the first golfer to win a tour event wearing shoes from Callaway Golf's new footwear collection. Sorenstam -- who won 13 of the 25 worldwide tournaments in which she played last year -- has yet to place lower than third on the LPGA Tour this season, having finished tied for third, second and now first in consecutive weeks.

Sorenstam's victory was the second consecutive LPGA Tour win for a player using a Callaway Golf(R) titanium driver. Callaway Golf won the driver usage count at the Office Depot Championship with 38 drivers in play, including 27 Great Big Bertha II Titanium Drivers. Callaway Golf also won the usage counts in fairway woods, irons and putters at the event, according to data from the Darrell Survey Company.

Callaway Golf drivers were also the winner on the course and in the usage counts at the first Japan Golf Tour event of the year.
