Federer vs del Potro | Kyrgios vs Karlovic | Isner vs Zverev 

• DAY 6 PREVIEW: Third round action on Monday at the Miami Open, presented by Itau, continues with both Swiss superstars in Stadium court action. No. 1 Stan Wawrinka and No. 4 Roger Federer are the only remaining Emirates top-ten players in the top half of the draw. Two more top-ten seeds are in action today—No. 8 David Goffin and No. 10 Tomas Berdych—along with U.S. stars No. 18 John Isner and No. 22 Sam Querrey.

In the opening men’s match on Stadium, Federer squares off against long-time rival No. 29 seed Juan Martin del Potro. The pair has played twenty times, but this is their first meeting since the 2013 Barclays ATP World Tour finals, where Federer defeated the Argentine in round-robin play. Del Potro has won three of the last five encounters, but the Swiss has emerged victorious all five times the pair has met at Masters 1000 series events.

In the last day session match, Isner will try to exact revenge on German #NextGen star Alexander Zverev, who beat him last fall in Shanghai, their only previous meeting. Isner reached the semi-finals here two years ago (l. to Djokovic), while Zverev is charting new territory, playing in the Miami third round for the first time.

In the evening session, Wawrinka will take on Tunisian Malek Jaziri, who ousted No. 31 seed Lopez on Saturday. Jaziri is looking for his first-ever victory against an Emirates top-ten opponent (0-9), and is facing the Swiss for the first time. Wawrinka is playing his first Masters-level event as the top seed, and is aiming to reach the quarter-finals in order to top his previous best showing here (2009, 2014 4th round).

On Grandstand, 2010 finalist Berdych takes on No. 24 Gilles Muller in their second career encounter. Muller beat the Czech last fall in Tokyo. Next up, Querrey goes for the upset against No. 14 Roberto Bautista Agut, who has defeated him twice in the past. The third men’s match is sure to be a big-serving clash between No. 12 Nick Kyrgios and No. 17 Ivo Karlovic. The Australian has won both previous encounters. Closing the day’s Grandstand action is Goffin against Diego Schwartzman, the No. 2 ranked Argentine, who upset Ferrer on Saturday. The head-to-head is knotted at one, and Schwartzman won the last match, in last year’s Antwerp semi-finals.

On Court 1, #NextGen Croat Borna Coric faces the French left-hander Adrian Mannarino, both of whom hold a losing record on the season. Each player needed to score an upset to reach the round of 32: Coric ousted No. 6 seed Thiem, and Mannarino surprised No. 32 Lorenzi. Mannarino reached the 4th round here in 2015 (d. Wawrinka, l. to Thiem), while Coric is making his first third-round appearance.

Jack Sock recorded yet another win this season on Sunday at the Miami Open presented by Itau, fighting hard under the lights to defeat Jiri Vesely 6-3, 7-6(0) and reach the round of 16.

A single break of serve was all the 13^th seed needed to take the opening set. Vesely raced to a 5-3 lead in the second set, but Sock fought back to level the match and was dominant throughout the tie-break. A volley winner on his first match point wrapped up the contest after one hour and 39 minutes. Sock improves his FedEx ATP Head2Head record against Vesely to 2-0.

Seventh seeds Ivan Dodig and Marcel Granollers prevailed in a hard-fought second-round tussle over Gilles Muller and Sam Querrey 6-4, 6-7(5), 10-6. Awaiting them in the last eight will be top seeds Henri Kontinen and John Peers or Americans Nicholas Monroe and Jack Sock.

Philipp Petzschner and Alexander Peya also reached the quarter-finals by rallying to defeat Alexander Zverev and Mischa Zverev 4-6, 6-4, 10-8. They’ll play either second seeds and defending champions Pierre-Hugues Herbert and Nicolas Mahut or the new combination of Brian Baker and Daniel Nestor.

A LOOK BACK

Jalisco Open (Guadalajara, Mexico): Mirza Basic of Bosnia & Herzegovina captured his first ATP Challenger Tour title since July 2015 (Recanati, Italy) by defeating #NextGenATP Canadian Denis Shapovalov 6-4, 6-4. The 25 year old weathered a difficult draw to prevail, taking out top seed Victor Estrella Burgos of the Dominican Republic in the quarter-finals and fourth seed Jason Jung of Taipei in the semi-finals.

The 17-year-old Shapovalov came into the final on a nine-match winning streak in Challengers, having won his maiden title last week on home soil in Drummondville. He also had a difficult path to the championship match, defeating good friend and fellow Canadian Vasek Pospisil in the second-round and former Top 15 player Jerzy Janowicz in the semi-finals.

Quanzhou Open (Quanzhou, China): Sixth seed Thomas Fabbiano continued his love affair with China by defeating qualifier and fellow Italian Matteo Berrettini 7-6(5), 7-6(7) in the championship match. Fabbiano also finished runner-up this month in Zhuhai, where he won the tournament last year.

The 20-year-old Berrettini drops to 0-2 in Challenger finals after finishing runner-up last November on home soil in Andria. He stood at No. 883 in the Emirates ATP Rankings this past October, but is projected to move well inside the Top 300 on the following Monday.

WHAT THE PLAYERS SAID

Basic: “The last title I had was in July 2015, so I’m very happy to be back and making some wins. I really enjoyed my time here. I knew it was going to be a tough match because Denis is young and up-and-coming, but I think I was solid and more patient than him today.”

A LOOK AHEAD

There are two Challengers on the schedule this week, with the $75,000 event in Leon, Mexico, taking top billing as it returns for the for the 15^th straight year. Estrella Burgos is the top seed once again and could face Shapovalov in the second-round. #NextGenATP Americans Ernesto Escobedo and Stefan Kozlov are the second and fourth seeds, respectively, while Pospisil is the third seed. Basic is in the draw and looks for another big week in Mexico.

The $50,000 tournament in St. Brieuc, France, is back for the 14^th consecutive year. Gerald Melzer of Austria is the top seed and Sergiy Stakhovsky of Ukraine is the second seed. #NextGenATP player and local favourite Quentin Halys also competes this week as the fifth seed.
