Nishikori enjoys Dallas win

The 28-year-old Japanese former world number four has spent five months on the sidelines since last August because of the problem and made his return to action at Newport Beach just over a week ago.

Nishikori, who has dropped to 27 in the world due to his absence, went out at the first-round stage in that event but bounced back well in Dallas.

And he secured $18,000 in prize money courtesy of a comfortable 6-1 6-4 final win against American world number 158, McDonald.

'I'm happy to win and be done,' Nishikori said. 'There were moments that were a little stiff, but I also feel like I came back to the game.

'I made it through a few tough matches. It was a good experience.'
