Rafael Nadal saved a championship point to beat Stefanos Tsitsipas 6-4, 6-7 (6/8), 7-5 on Sunday and claim a 12th Barcelona Open title in the ATP’s longest match of 2021.

The Spaniard secured his first title of the year and 87th of his career, denying Tsitsipas back-to-back triumphs following his maiden Masters 1000 title at Monte Carlo last week.

Nadal avenged his Australian Open quarter-final loss to Tsitsipas and will return to second in the ATP rankings on Monday by climbing back above Daniil Medvedev after his marathon 3-hour 38-minute win.

Second seed Tsitsipas, a Roland Garros semi-finalist in 2020, had won all 17 sets on clay this season and entered the final unbeaten on the surface in nine matches.

The Greek built up a 4-2 lead in the opening set after breaking Nadal in the third game but dropped his serve twice in succession as the 20-time Grand Slam champion hit back to win four games in a row.

Fifth-ranked Tsitsipas, who won just three games when the pair met in the 2018 final here, again procured an early break in set two but Nadal responded to haul himself level at 3-all.

Nadal failed to convert two match points as Tsitsipas clung on to hold when trailing 5-4, with the Spaniard saving three break points in the very next game.

Nadal took a 4-2 lead in the tiebreak but the momentum swung back towards Tsitsipas as he won four straight points, blowing two set points before forcing a decider at the third attempt after a double fault from his opponent.

In sharp contrast, the third set went on serve without a single break opportunity until Tsitsipas edged to within a point of the title with Nadal on the ropes serving at 4-5.

Nadal survived though and finally converted his fourth break chance in the following game, snuffing out a Tsitsipas break point in the final game before clinching his 61st clay-court title.

His 12 Barcelona victories are second only to his 13 Roland Garros trophies.
