Roger Federer defeated American, John Isner, 6-1, 6-4, to win the 2019 Miami Open and his 101st career title on Sunday.
The 37-year-old world number five broke in the opening game and took the first set in 24 minutes.
Playing in his 50th Masters final, the fourth seed produced typically sublime ground strokes and wrapped up the match in one hour and three minutes.
The feat was also the 28th Masters title for Federer, who struck 17 winners overall, including six off his elegant backhand.
“What a week it’s been for me,” the Swiss said.
“I’m just so happy right now. It’s unbelievable. I played here in 1999 for the first time and here I am in 2019. It means a lot to me.”
Following his victory at the Dubai championships, Federer becomes the first two-time champion on the ATP Tour this season, ending a streak of 19 different winners in 2019.
Isner, his opponent and defending champion, came into the first meeting between the pair in Miami, having not dropped a set throughout the tournament, winning nine of the 10 sets in the process by tie-break.
Federer had won all four of their previous matches on hard courts.
The 20 Grand Slam winner asserted his dominance from the outset, losing only one point on serve in the opening set.
Isner had treatment on his left foot at 4-3 down in the second set, but the match soon ended as Federer improved his overall record against the home favourite.
