His answer was simple: "Drive the ball well. Look at the two previous Turnberry winners, Norman and Price. Both drove it brilliantly. Same this week."
Casey's coach, GOLF Magazine Top 100 Teacher and CBS on-course analyst Peter Kostis, told me, "Drive it poorly here and you won't finish."
To avoid Turnberry's deep rough and handle a forecast that calls for a mix of sun, rain and wind, players will need to be especially dialed-in with their drivers. For Casey, that means he's got to be accurate with his Nike SQ Tour (8.5°).
According to TaylorMade, Rod Pampling practiced on Tuesday with an R9 460 that was cut down to just 43.5 inches. That's an inch and a half shorter than standard length. Generally, a shorter driver will allow for more control and feel, but less power. The effect is similar to a baseball player choking down on his bat.
According to Titleist, Adam Scott (right) tested a shorter driver in the days leading up to the British Open. The Aussie has experimented with a 909 D2 (9.5°) with a UST Proforce V2 86 shaft that is just 44.25” long.
