British number one Kyle Edmund produced a classy performance to beat Milos Raonic in straight sets and reach the fourth round of the Miami Open.
Edmund, 24, did not face a single break point as Canada's Raonic struggled with a back injury which needed physio and medication on court in the second set.
In blustery conditions, Edmund's forehand was key as he took two of his three break points in a 6-4 6-4 win.
He now faces defending American champion John Isner in round four.
Isner overcame Spaniard Albert Ramos-Vinolas 7-5, 7-6(6) on Sunday.
"Isner is a similar match up in that you have to try to get his serve back," Edmund said after his win over a player ranked eight places above him.
