Sinner sees off Lehecka to complete Sunshine Double without dropping a set

• World No 2 seals Miami Open final 6-4, 6-4

• Sinner won in Indian Wells earlier in March

Jiri Lehecka entered his first Masters 1000 final at the Miami Open in the best serving form of his life. He had won every service game in the tournament, a feat achieved by just eight men at this level before him. The ease with which he brushed aside all nine break points against him reflected his confidence.

It took two return games for Jannik Sinner to viciously drag the Czech back down to earth. Ten minutes in, Sinner had already broken Lehecka’s unbreakable serve. As has usually been the case over the past few years, Sinner burst into the lead and refused to let it go.
