Three-time champion Taylor Fritz met rising star Joao Fonseca for the first time at tour level in Eastbourne, playing for a spot in the quarterfinals at the Lexus Eastbourne Open on Wednesday.
With the score locked at a set apiece, 6-3, 6-7(5), play was suspended due to darkness; action will resume at the grass-court event on Thursday.
Within 14 minutes of the opening set, the defending champion had taken a 4-1 advantage over the Brazilian player.
Dictating the rhythm from the get-go behind his powerful service, Fritz extended his lead, wrapping up 6-3 with an ace in just 26 minutes.
Fonseca held his nerve, kicking up a level to make a solid start to the second set, holding to love.
The top seed found himself under pressure to close out a lengthy sixth game, but momentum shifted as he put the pressure straight back on the Rio de Janeiro native, who saved a break point to stay ahead at 4-3.
From there, a tight second set went into an edgy tiebreak that the reigning Nitto Next Gen champion did not let slip, pulling ahead 6-5 to eventually seal the deal 7-5, forcing a decider.
The teenager found his groove, easily generating power on the forehand while surging at the net with accuracy, raising to the occasion at Devonshire Park.
Fritz arrived in Eastbourne off the back of winning his first title of the season at the BOSS Open in Stuttgart last weekend.
On British soil, the American player, who is the only man to win the ATP 250 three times in tournament history, received a first-round bye, facing Fonseca for the first time on tour for a spot in the last eight.
Meanwhile, the 18-year-old, who has excelled on both clay and hard-court surfaces, is struggling with his transition to grass.
Last week, he fell to Italian Flavio Cobolli in Halle, competing in his opening round at the ATP 500 venue. Nonetheless, he achieved a confidence-boosting result.
The Buenos Aires Open winner rallied from a set down to beat Zizou Bergs 6-7(8), 6-0,6-3, claiming the first grass-court match of his career on Monday.
