<p>The 28-year-old Californian posted a solid one-under 71 to follow up his impressive 64 on Thursday. <br /><br />Kaymer, composed and as tidy as ever, was bogey free as he shot a 70 and he looks well placed to keep hold of his top spot in the ranking given Britain's Lee Westwood -- who can return to number one with a win here -- is nine shots off the lead. <br /><br />Westwood, who was grouped with Kaymer, shot two over on Friday leaving the German confident he would remain atop the rankings for some time yet. <br /><br />One player Kaymer will be wary of, this weekend at least, is Molinari, who moved up the leaderboard with a four-under 68 built around some excellent work around the greens.</p>
