There is plenty on the line as Roger Federer and John Isner clash for the title at the Miami Open presented by Itau.
The three-time champion Swiss is not only bidding for a 28th ATP Masters 1000 crown, but also a 101st title at the tour-level. Federer has been at his ruthless best in Miami, having won 10 consecutive sets to reach the championship match.
On the other side of the net, Isner is hoping to add a second Masters 1000 shield to his trophy case with a successful title defence in Miami. Last year, he defeated Alexander Zverev for the crown and on Sunday he is targeting yet another Top 5 scalp for the prestigious title.
It is the oldest combined final in the history of the Masters 1000 tournament. While 37-year-old Federer leads the FedEx ATP Head2Head by a count of 5-1, it was 33-year-old Isner who claimed their most recent meeting, prevailing on the indoor hard courts of Paris in 2015.
Much has changed since they last met four years ago, but Federer's serving prowess against Isner remains. Entering Sunday's final, he had saved a combined 16 of 16 break points against the North Carolina native.
