By Martyn Herman LONDON (Reuters) -World number one Jannik Sinner shrugged off any fears about his injured elbow with a clinical defeat of powerful young American 10th seed Ben Shelton to reach the Wimbledon semi-final for the second time on Wednesday.

Two power hitters competing in a slugfest early transitioned into a calculated display of consistency from World No. 1 Jannik Sinner during Wednesday's straight sets win over Ben Shelton in the quarterfinals at Wimbledon.

Jannik Sinner sure didn’t play like someone dealing with an injured right elbow Wednesday, using terrific serving and his usual booming forehand to dismiss 10th-seeded Ben Shelton 7-6 (2), 6-4, 6-4 and earn a second appearance in the Wimbledon semifinals.
