Tim Henman's miserable year continued in the Cincinnati Masters with a first-round exit against Argentine Juan Ignacio Chela.

Given a wildcard to the event, Henman, who lives at Aston Tirrold, near Didcot, was beaten 4-6, 6-3, 3-6.

Chela broke serve in the seventh game to take the first set, but Henman fought back well to level the match.

The British No 2's serve again proved fragile in the third set, allowing Chela to easily close out the match and leave Henman without a hard-court win this season.
