Roberto Bautista Agut stands in the way of Stefanos Tsitsipas and his first grass-court title.
Making his debut at the Mallorca Championships, Tsitsipas sealed his maiden appearance in a grass-court final by cruising past Benjamin Bonzi 6-4 6-4 on Friday.
The world number six has now reached four finals this season, having lost two of the previous three – winning on clay at the Monte Carlo Masters.
It was the second meeting between the pair in as many weeks, with the Greek having also downed Bonzi at the Halle Open.
And Tsitsipas now has a chance to warm up for Wimbledon in winning fashion.
"It was a good match. I am very happy today," Tsitsipas said in his on-court interview. "I have played a final a week before a grand slam before. It was the year I made the final at Roland Garros, in Lyon.
"It worked out pretty well to have that final and consistency of matches. It is different this time. We are talking about a different surface, so we will see."
Tsitsipas has now claimed a tour-leading 39 wins this season, but standing between the 23-year-old and silverware is Spaniard Bautista Agut, who reached a 20th career final by beating Antoine Bellier 7-6 (7-5) 6-2.
Like Tsitsipas, Bautista Agut is aiming for a second title of the season.
At the Eastbourne International, two Americans will vie for the title after Indian Wells Masters champion Taylor Fritz saw off a tough challenge from Alex de Minaur while Maxime Cressy defeated home favourite Jack Draper 7-6 (7-5) 6-7 (2-7) 6-3.
Fritz, who triumphed at Eastbourne in 2019 – similarly against an American, in Sam Querrey – but has found his best form hard to come by of late, also needed three sets to get the better of De Minaur, eventually succeeding 6-1 6-7 (5-7) 6-3.
"It's amazing," Fritz said. "I was having a bit of a rough start coming back from injury to the grass season, and then I came here and the first day I was here I just immediately felt like I was playing good tennis again.
"I just have a lot of confidence being here, obviously great memories, so I'm really excited to come back out and play for the title again."
