Branden Grace’s seven-stroke victory at the Alfred Dunhill Championship is the first worldwide win for the Callaway Big Bertha Alpha Double Black Diamond, a driver aimed at better amateurs and tour players.
Grace’s final-round 68 helped him turn a one-stroke lead through 54 holes into his fifth European Tour victory and first since October 2012. The 26-year-old South African finished sixth in driving distance (314.1 yards) at Leopard Creek CC and 21st in driving accuracy (64.3%). The DP World Championship in November was Grace’s first event with the Double Black Diamond. The club made an immediate impact, helping him to a ninth-place finish while ranking 10th in driving accuracy (75%) and fourth in distance (307.4 yards).
Grace’s Double Black Diamond has 8.5° of loft and a 45-inch Fujikura Fuel 75-gram extra-stiff shaft. He has six-gram weights in both the heel and toe and the gravity core is in the down position. According to European Tour rep Ian Dryden, Grace likes the head shape, low spin rates and the slight fade bias the club provides.

Also aiding Grace en route to victory were his 2013 Callaway X Forged irons. His ball striking improved drastically over the 2013-14 season, when he finished 47th on the European Tour in greens in regulation (70.1 %). At the Alfred Dunhill, Grace finished fifth in that stat (79.2%).
