LONDON

From champions Novak Djokovic and Angelique Kerber, to runner-up Serena Williams, this edition of Wimbledon was all about comebacks of various sorts.

When Djokovic won his fourth title at the All England Club and first at a Grand Slam tournament in more than two years by beating Kevin Anderson 6-2, 6-2, 7-6 (3) on Sunday, it was the culmination of what he called a “journey” and a “process” as he returned from surgery to his right elbow.

Kerber collected her first Wimbledon championship with a 6-3, 6-3 victory over Williams on Saturday to mark a turnaround from a rough 2017 that saw her slip from No. 1 in the rankings and deal with two first-round exits at majors.

And while Williams didn’t win what would have been her eighth Wimbledon singles trophy, her run to the final just 10 1/2 months after a difficult childbirth and complications involving blood clots served as, in Kerber’s words, “such an inspiration for everybody, for all of us, for every person watching you.”

Here is what else we learned at Wimbledon in 2018:

TIE-BREAKER TIME? — Anderson’s 26-24 victory in the fifth set against John Isner in a semifinal that lasted more than 6 1/2 hours was the second-longest Grand Slam match ever and renewed a debate about the rules: Should Wimbledon adopt a fifth-set tiebreaker? Currently, the U.S. Open is the only major that decides matches that way. “It absolutely needs to change,” said Anderson’s coach, Brad Stine.

THE BIG 3 — Men’s tennis is back to having its Big 3 of Roger Federer, Rafael Nadal and Djokovic. Federer and Nadal had combined to win six majors in a row until Djokovic got back in on the action. Each member of that trio has been counted out in recent years, but they just keep on winning. All can excel on hard courts, Djokovic’s best surface. So the next couple of months should be entertaining.

OLD GUYS — Djokovic, 31, and Anderson, 32, made this Wimbledon final the first in the Open era with a pair of men older than 30. Add in Nadal, 32, and Isner, 33, and it was the first quartet of thirty-something semifinalists at any major in the past 50 years. Which means they all deserve kudos, but also raises the question: Where are all the young guys? No up-and-comers reached the quarterfinals. One breakthrough did come from Stefanos Tsitsipas, a 19- year-old from Greece who made it to the fourth round.
