Germany’s Alexander Zverev looked every bit a serious French Open title contender as he crushed claycourt specialist Dominic Thiem 6-4 6-4 in the Madrid Open final on Sunday. Oddly the 21-year-old world number three is yet to progress past the last 16 of a grand slam but he now has three Masters 1000 titles to his name and against Thiem played with a swagger that suggests that his record in the majors will improve soon. The second seed broke a nervy-looking Thiem in the opening game thanks to a double-fault and was never really challenged as he produced a clinical serving display in which he did not even offer up a break point. Zverev, who did not face a break point all tournament, broke again right at the start of the second but squandered the chance of a double-break two games later as Thiem, conqueror of Rafael Nadal in the last eight, hung on. There was no chance of a let-up from Zverev though and he remained focused throughout, winning on his first match point when his Austrian opponent returned long.
