Del Potro rallies as Ferrer falls
Juan Martin del Potro recovered in the final set to claim a 6-4, 4-6, 7-5 victory against Ivan Dodig in the second round of the Rogers Cup.
Dodig famously knocked Rafael Nadal out of the event at the same stage two years ago and took advantage of Del Potro's apparent lack of fitness to open up what should have been a decisive advantage.
Newly-crowned Citi Open champion Del Potro regained the one service break before Dodig had an opportunity to serve for the match with the score at 5-4 in the third set.
The Argentine then broke serve to love the following game to clinch the victory after two hours and 18 minutes of play.
In the next round, the former US Open champion will come up against Canadian number one Milos Raonic, who beat Gstaad champion Mikhail Youzhny 6-4, 6-4 in the second round.
"It was quite a bit better," Raonic said of his performance on Wednesday.
"Just a lot more fluid, a lot more within myself.
"Today still I made a few errors in some critical situations where I wouldn't want to, but mostly I played clean," he said.
"I think keep working away, those little pieces come together better and those errors disappear."
While Del Potro came from behind to win on Wednesday, world number three David Ferrer lost in his first match since he succumbed to Del Potro in the quarter-finals of Wimbledon.
The Spaniard went down with a whimper as Russian qualifier Alex Bogomolov Jr. claimed a routine 6-2, 6-4 victory.
Bogolomov's next opponent is Nikolay Davydenko, who advanced with a 6-1, 4-6, 6-3 win over Spaniard Pablo Andujar.
