MIAMI - German fourth seed Alexander Zverev showed his quality to escape a tight first set en route to a 7-6(4) 6-3 win over Christopher Eubanks at the Miami Open on March 25 to set up a fourth-round clash with Russia's Karen Khachanov.

Zverev limited his unforced errors, converted his two break point opportunities and saved four of the five break points he faced before closing out the one hour and 44-minute contest with a forehand volley into the open court.
