Three Americans reached the Delray Beach Open quarter-final on Saturday, with two of those entering the last eight for the first time on the ATP level. After eight surgeries between 2009-2018, Christian Harrison is back on the winning way, advancing into the quarters for the first time in a career.
World no. 789 qualified for the main draw and scored his first ATP win since Newport 2018. Not stopping there, Christian took down the top seed Christian Garin 7-6, 6-2 in an hour and 30 minutes for another essential victory and the place in the last eight.
Harrison lost serve twice and scored four breaks, prevailing in a tight opener and marching towards the top in the second. The American came from 3-0 down in the first set and saved more break points at 3-4 to remain in contention.
Christian scored a break at 5-5 and earned three set points on his serve, wasting them all to suffer a break but remaining focused to grab the breaker 7-3. Harrison rattled off the last four games at 2-2 in set number two, forging his way towards the finish line and entering the quarters.
Gianluca Mager defeated the former Delray Beach champion Sam Querrey 7-6, 6-1 in an hour and 22 minutes. Querrey led 5-3 in the first set and had a set point at 6-5 in the tie break, squandering his chances and losing the breaker 10-8.
Christian Harrison and Sebastian Korda are the first-time ATP quarter-finalists.
That gave a massive boost to Mager, who repelled break chances at the beginning of the second set and stole Querrey's serve in games four and six to cross the finish line.
The young American Sebastian Korda bested the 5th seed and compatriot Tommy Paul 4-6, 6-3, 6-2 in two hours and eight minutes. Paul grabbed two breaks in the opener for 6-4 but couldn't repeat that in sets two and three, as Korda saved all break points to keep the pressure on the other side of the net.
The youngster earned a double break in set number two and clinched 22 of the last 30 points in the final set for the maiden ATP quarter-final. The 2nd seed John Isner needed an hour and 33 minutes to prevail over Thiago Monteiro 6-4, 7-6 and kick off the season with a win.
The American landed 22 aces and dropped 16 points behind the initial shot, keeping his serve intact and challenging Monteiro to repeat that if he wanted to stay in the match. Returning at 5-4, John found the rhythm on the return and earned a break and a set with a thundering forehand down the line winner.
The second set went into a tie break, and Isner won it 7-4 following a beautiful volley winner at the net to seal the deal and advance into the quarters.
