Juan Martin del Potro: Sam Querrey beats Argentine in comeback bid

Del Potro confirmed he will play in the BNP Paribas Open in Indian Wells next month

Juan Martin del Potro said he "more than won the tournament" despite his comeback at the Delray Beach Open ending in a semi-final defeat.

The 27-year-old former world number four lost 7-5 7-5 to American Sam Querrey on his return after an 11-month absence following two wrist operations.

"There are so many positive things," the Argentine said. "I'm looking forward to the future because I can make a plan for playing tournaments."

Querrey faces Rajeev Ram in the final.

Ram upset fourth seed Grigor Dimitrov 6-4 6-3 to set up an all-American showpiece in Florida.

Despite not making the final, 2011 Delray Beach champion Del Potro performed well in his four matches - the same number he played in the whole of 2015.

He forced Querrey to produce his best display of the tournament, with the world number 61 breaking at 5-5 in each set to seal victory.

Del Potro has suffered a succession of injuries since his 2009 US Open triumph and was ranked outside the top 1,000 before this tournament.
