Juan Martin del Potro’s fairytale run came to an abrupt end as the Argentine lost to American Sam Querrey 7-5 7-5 in the semi-final of the Delray Beach Open on Sunday.
The former U.S. Open champion Del Potro made his comeback at Delray Beach after an 11-month layoff following two surgeries on his left wrist.
He had looked strong in his run to the semi-finals but Querrey checked his momentum by breaking his powerful serve in each set at 5-5 -- the only two breaks of the match.
Del Potro, 27, was aiming to recapture his magic at Delray Beach where he enjoyed comeback success by winning the 2011 title after fighting his way back form wrist surgery.
Former world number four Del Potro, who stunned none other than Roger Federer in the 2009 final at Flushing Meadows, has been frustrated by a succession of injuries since his sole grand slam title.
Ranked outside the top 1,000 at Delray Beach, he showed flashes of his old form, displaying good court coverage and growing confidence in his groundstrokes throughout the week save for two poor service games against Querrey.
Querrey will face Rajeev Ram in the final after the American upset fourth seed Grigor Dimitrov 6-4 6-3 in the other semi-final.
