French Open champion Jelena Ostapenko summoned all of her fighting spirit in going the distance once more against Francoise Abanda to reach Wimbledon round three.
The Latvian, a shock winner at Roland Garros last month, struggled through in three sets against Aliaksandra Sasnovich in her opener and she was given another stern test by Canadian qualifier Abanda on Court 12 on Wednesday.
In a battle of two talented but erratic 20-year-olds, remarkable winners and sloppy unforced errors were abundant in equal measure but it was the 13th seed who ultimately kept her cool at the crunch to advance 4-6 7-6 (7-4) 6-3.
Four mistakes from Ostapenko - including a double fault - handed Abanda a 4-2 lead in the first and although the Latvian broke back to stay in the set, her opponent responded immediately to clinch the lead.
The pair twice traded breaks in the second, where this time it was Ostapenko's turn to lose her serve when trying to see out the set, but she shrugged off that disappointment by winning the tie-break courtesy of a backhand volley.
Seemingly unbowed, Abanda broke to start the decider but Ostapenko was soon back on serve before taking a 5-3 lead and then sealing victory with an inside-out forehand winner which elicited a scream of delight.
