Nishikori Extends Challenger Winning Streak To Six; Watch Match Replay

Kei Nishikori continued his impressive return on the ATP Challenger Tour Tuesday with a convincing 6-1, 6-2 win in the first round of the Cranbrook Tennis Classic in Bloomfield Hills, Michigan.

The former No. 4 player in the Pepperstone ATP Rankings last month returned for his first action in 20 months. The 33-year-old has not missed a beat. Nishikori won his return event in Palmas del Mar, Puerto Rico with the loss of just one set.

On Tuesday, Nishikori lost just three games, the most lopsided scoreline of his comeback. The 12-time ATP Tour titlist saved all four break points he faced and converted four of his five break chances to advance after 66 minutes. The wild card will next play former World No. 53 Denis Kudla or Tunisian Skander Mansouri.

Nishikori began his comeback without a Pepperstone ATP Ranking. With his six victories, he has returned to the Top 500 of the Pepperstone ATP Live Rankings.
