JACK'S ACE IN THE PACK

Draper fires down 31 big ones to land Stuttgart semi spot as he sets his sights on World's top 10

- NEIL SQUIRES

JACK DRAPER believes a new bully-boy attitude has set him up for a crack at the world's top 10.

The 22-year-old, who will replace Cam Norrie as British No.1 on Monday, muscled his way into the semi-final of the Stuttgart Open with a third-set tie-break win over world No.28 Frances Tiafoe that saw him send down 31 aces.

If he can land his first ATP title this weekend, Draper will move into the world's top 30 for the first time on the back of his beefed-up approach.

He said: "The serve's a big factor in all of this, but also I've come up the court massively on my return position.
