Surprise to the strength.

The score is 15/30. You just missed your first serve and you now need to weigh up where to direct the second. Safety to the backhand return, right? Not so fast …

An Infosys ATP Beyond The Numbers analysis of the current ATP Top 20 identifies that a vast majority of second serves do go to the backhand return at this specific point score, but a higher percentage of points are won surprising with a second serve down the T to the forehand return.

The best way to understand this strategy dynamic is to know the difference between primary and secondary patterns. Primary patterns are the prime movers that players run most often, such as hitting forehands from the back of the court, playing cross court, and directing second serves to the returner’s backhand wing.

Secondary patterns are lethal when they are combined with the element of surprise. Secondary patterns include serve and volley, attacking down the line, drop shots, and hitting a second serve to the opponent’s more potent forehand return.

Primary patterns are run seven or eight times out of ten and are also meant to condition the opponent’s mind that a specific pattern of play will be run again in the near future. Secondary patterns are best employed AFTER primary patterns have been run.

Bait and switch.

The data set of 1489 second serves at 15/30 comes from ATP World Tour Masters 1000 events and Nitto ATP Finals from 2011-2018. The following breakdown shows just how few second serves go down the T to the forehand (24%), but how this specific location also delivers the highest win percentage (62%).

Kevin Anderson was the peak performer in the Top 20 with second serve points won serving down the T at 15/30. The top three performers at each location are highlighted below.

2nd Serve at 15/30 = Down The T
1. Kevin Anderson = 87% (13/15)
2. Jack Sock = 83% (5/6)
3. Sam Querrey = 82% (9/11)

2nd Serve at 15/30 = At The Body
1. Diego Schwartzman = 71% (5/7)
2. Jack Sock = 70% (21/30)
3. Roberto Bautista Agut = 67% (8/12)

2nd Serve at 15/30 = Out Wide
1. Jack Sock = 67% (10/15)
2. Sam Querrey = 65% (11/17)
3. John Isner = 64% (33/52)

Jack Sock impressively featured in the top three in all three categories. Overall, 15 of the 20 players in the data set had a higher win percentage serving down the T with a surprise second serve to the forehand over the expected second serve out wide to the backhand. It’s important to note that a small percentage of returners were left-handed, which flips the side of the return stroke.

Not all players followed the same pathway with second serve locations at 15/30.

Juan Martin del Potro – the only player that served more down the T (24) than he did down the middle (23), or out wide (15).
Roger Federer – hit the most down the T (57), which was almost as many as he directed out wide (62).
Novak Djokovic – mixed a lot, with 59 out wide, 58 at the body, and 55 down the T.
Milos Raonic – hit many more serves out wide (34) than down the T (8).

The mental side of the game is clearly in play here. Hitting a second serve at 15/30 suggests vulnerability for the server. Cleverly mixing to the forehand return may seem riskier on the surface, but the element of surprise makes this specific location the highest performer.

Dominic Inglot and Robert Lindstedt secured their place in the TEB BNP Paribas Istanbul Open quarter-finals on Wednesday when they knocked out Roman Jebavy and Florin Mergea 7-6(4), 6-1 in 71 minutes. The pair has won one ATP World Tour title together at the 2015 Winston-Salem Open (d. Butorac-Lipsky). The British-Swedish team will next challenge fourth seeds Ken Skupski and Neal Skupski, champions at the Open Sud de France (d. McLachlan/Nys) in February.

At the Millennium Estoril Open, top seeds John Peers and Jean-Julien Rojer joined forces to knock out Argentines Guillermo Duran and Andres Molteni 6-2, 7-6(2) in 75 minutes. They will now meet Jonathan Eysseric and Joe Salisbury, who scraped past Sander Arends and Adil Shamasdin 6-3, 3-6, 10-6.

However, two seeded teams: third seeds Marc Lopez and David Marrero, and fourth seeds Marcelo Demoliner and Santiago Gonzalez fell in the first round.

Despite recovering from a 1-4 deficit to win the first set, Lopez and Marrero were beaten by Wesley Koolhof and Artem Sitak 6-7(5), 6-4, 10-3 in one hour and 35 minutes. Dutchmen Robin Haase and Matwe Middelkoop, winners at the Tata Open Maharashtra and Diema Xtra Sofia Open this year, knocked out Demoliner and Gonzalez 6-4, 6-4 in 65 minutes.

At the BMW Open by FWU, third seeds Nikola Mektic and Alexander Peya defeated Germans Kevin Krawietz and Maximilian Marterer 7-5, 6-4 for a place in the semi-finals. Peya partnered Bruno Soares to the 2015 title (d. Zverev/Zverev). Fourth seeds Max Mirnyi and Philipp Oswald battled hard to beat Daniel Masur and Rudolf Molleker 3-6, 7-5, 10-6 in their opening match.

Daniel Nestor, who is contesting his 28th and final season as a pro, has compiled a 1061-478 doubles match record, including 91 titles. He has lifted four trophies on German soil at Hamburg in 1996 and 2003 (w/Knowles) and 2008 (w/Zimonjic), and at 2001 Halle (w/Stolle).

Top seed Alexander Zverev recovered from a set down to defeat countryman Yannick Hanfmann 6-7(12), 6-4, 6-2 at the BMW Open by FWU on Wednesday.

“I am always happy to get a win like that,” reflected Zverev. “Obviously [Hanfmann] played one of the best matches of his life today, so I wish him all the best and I hope he is going to continue playing like this in the next few weeks.”

The defending champion appeared to be in danger of an early upset after Hanfmann converted his seventh set point in a marathon first-set tie-break, but Zverev put the disappointment of failing to convert two set points of his own behind him to secure victory. The 21-year-old German improves to 9-3 in the Bavarian capital and will bid for a tenth victory at the event against Jan-Lennard Struff.

“It was great,” said Zverev. “I love playing in Germany as everybody knows. I love playing in front of my home crowd.”

Zverev leads Struff 3-0 in their FedEx ATP Head2Head series, most recently defeating his compatriot in three sets at the Rolex Monte-Carlo Masters last month.

Australian Open semi-finalist Hyeon Chung cruised into the BMW Open by FWU quarter-finals on Wednesday, defeating Munich native Matthias Bachinger 6-1, 6-1.

Chung, who broke into the Top 20 of the ATP Rankings for the first time on 2 April, lost only three first-service points in the 58-minute clash to record his 19th win of the season. The 22-year-old also saved all five break points he faced and converted five of his seven break opportunities in his first appearance since losing to eventual champion John Isner at the Miami Open presented by Itaú.

The inaugural Next Gen ATP Finals winner will face 2014 champion Martin Klizan for an opportunity to equal his 2017 debut result at the event (l. to Pella).

Slovakian qualifier Klizan recovered from a 0-3 deficit in the deciding set to beat Mirza Basic of Bosnia & Herzegovina 4-6, 6-3, 7-5 in two hours and three minutes. It was his ninth win in 10 matches at the ATP World Tour 250 tournament.

Jan-Lennard Struff won his all-German encounter with Yannick Maden 6-3, 3-6, 6-3. The World No. 62 hit 12 aces in the one-hour, 40-minute win to improve to 8-4 at the event. Struff won six matches from qualifying in 2014, before falling to Italy’s Fabio Fognini in the semi-finals.

Did You Know?
This will be the second consecutive year that Alexander Zverev and Jan-Lennard Struff have met in the BMW Open by FWU quarter-finals. En route to the title last year, Zverev defeated Struff 3-6, 7-6(3), 7-6(5).

Roger Federer announced on Wednesday that he will return to ATP World Tour action at the Mercedes Cup, held 11-17 June.

The 36-year-old will appear in Stuttgart for the third time in his career, after falling in the first round in 2017 (l. to Haas) and reaching the semi-finals in 2016 (l. to Thiem). Federer won two titles on grass in 2017 (Halle, Wimbledon) and will be bidding for an 18th title on the surface in Stuttgart, which will mark the beginning of his grass-court schedule leading towards The Championships at Wimbledon.

Federer shared the news with more than 15 million fans on Facebook on Wednesday morning. “Excited to announce that I will be coming back to Germany for the Mercedes Cup in June,” said Federer. “Looking forward to seeing you at the grass courts in Stuttgart!”

The Swiss star holds a 164-24 FedEx ATP Win/Loss Record on grass, winning 87.2 per cent of matches on the surface. Federer will be joined in Stuttgart by defending champion Lucas Pouille, Australia’s Nick Kyrgios, 2016 Wimbledon finalist Milos Raonic and reigning Next Gen ATP Finals champion Hyeon Chung.

Following on from Stuttgart, Federer will travel to Halle in search of a record 10th title at the Gerry Weber Open, having triumphed for a ninth time at the event in 2017 (d. Zverev).
