The 4th seed Hubert Hurkacz is through to the quarter-final in Delray Beach following a convincing 6-2, 6-2 triumph over Daniel Elahi Galan in 59 minutes. Hubert dropped nine points in eight service games, fended off the only break point he faced and broke the rival's resistance with four breaks from seven opportunities.
The Pole converted the fourth break chance in the opening game following Elahi Galan's terrible forehand and held at 15 to cement the advantage and move 2-0 up. Hubert forced an error from Daniel at 3-1 to secure another break of serve and held at love at 5-2 to wrap up the opener.
Elahi Galan netted a forehand in the second set's first game to fall further behind and suffered another break at 1-3 when Hurkacz placed a smash winner. Serving at 5-2, Hubert fired two service winners to move over the top and kick off the new season in style.
The Briton Cameron Norrie ousted the Frenchman Adrian Mannarino 6-2, 7-5 in an hour and 35 minutes, scoring the third win from four matches against the more experienced opponent. Norrie experienced two breaks and delivered five to stay in front, erasing the second set deficit to advance in straight sets.
The Briton grabbed three breaks in the opening set for 6-2 and found himself 3-0 down in set number two. Mannarino couldn't stay in front, though, losing serve in game five and allowing Norrie to rattle off 12 of the last 15 points and seal the deal before the tie break.
Hubert Hurkacz and Frances Tiafoe are through to Delray Beach QF.
The 8th seed and former champion Frances Tiafoe defeated Bjorn Fratangelo 6-4, 3-6, 6-1 in an hour and 49 minutes to join Hurkacz in the last eight. The better-ranked American saved five out of seven break points and stole the rival's serve four times to emerge at the top.
Frances claimed four straight games from 4-2 down in the opener to take it 6-4 and avoid an early setback. Fratangelo found his best tennis in set number two and won it with a single break, hoping for more of the same in the decider.
Starting all over, Tiafoe won the first five games and sealed the deal soon after that for the third Delray Beach quarter-final in the previous four years. A qualifier Roberto Quiroz ousted the veteran Ivo Karlovic 6-2, 6-4 in 59 minutes, dropping only five points behind the initial shot and stealing the Croat's serve three times for the first ATP quarter-final at 28.
Karlovic defeated Pablo Andujar in the opening round but stood no chance in this one, struggling on both serve and return to push the Ecuadorian through.
