The World No: World No. 2 Jannik Sinner beat home hope Alex Michelsen 7-5, 7-6(4) to enter Miami Open quarterfinal, keeping his mission to complete the coveted ‘Sunshine Double’ on track.

The 24-year-old Italian is just the third man to reach the quarterfinals on his first five appearances at the Miami Open, joining Yannick Noah and Stefan Edberg.

Indian Wells champion Sinner rallied from 2-5 in the second set to complete a one-hour, 42-minute triumph and improve his tally of consecutive sets won at Masters 1000 events to a record-extending 28.
