Milos Raonic, a finalist at the Rogers Cup in Montreal back in 2013 returns to the Rogers Cup in Toronto this year after an amazing run to the final at Wimbledon earlier this month.
Yen Hsun-Lu will be hoping to hand Raonic his second consecutive early defeat at the Rogers Cup and the player from the Chinese Taipei will be full of confidence following his victory over Alexander Zverev.
The big-serving Canadian will sense this as a good opportunity to reach the final in Toronto as former champions Andy Murray, Roger Federer, Rafael Nadal and Jo-Wilfried Tsonga are all absent from the event.
Raonic announced that he will not be representing Canada at the Rio Olympics due to fears of the Zika virus and the fourth seed will have a slight advantage of those competing in Rio, going forward at the US Open, the only Slam that has eluded him from reaching the quarterfinals or better.
How they got here
Raonic received a bye in the first round as the fourth seed, but that doesn't guarantee victory as the Canadian found out first-hand last year losing to Ivo Karlovic in the second round.
Lu faced young German Zverev in the first round of the Rogers Cup and he recorded an impressive straight sets 7-5, 6-3 victory over Zverev, who reached the semifinals of the Citi Open last week in Washington.
Raonic's notable results
The Wimbledon finalist had a good start to the 2016 campaign after recovering from a foot injury that ruled him out of the French Open last year.
The Canadian began the year with a flawless 9-0 record and he picked up a title in Brisbane against Federer at the start of the year gaining revenge for his defeat to the 17-time Grand Slam champion in the final the previous year.
Raonic's streak was ended at the Australian Open, competing in his second Grand Slam semifinal and first in Melbourne losing to Andy Murray despite leading a set and two sets to one but an injury hampered Raonic's performance. It was a good run for Raonic as he produced an eye-opening victory over 2014 champion Stan Wawrinka in five sets in the fourth round
The Canadian returned to competitive tennis for the two Masters 1,000 events on the North Amerian hard courts. He produced wins over seeded opponents Bernard Tomic, Tomas Berdych, Gael Monfils, and David Goffin but he was thrashed 6-2, 6-0 in the final by world number one Novak Djokovic in Indian Wells.
Raonic reached the quarterfinals of the Miami Open losing to Nick Kyrgios in straight sets.
An average clay court season was to follow for Raonic on his weakest surface but he reached the quarterfinals of the Monte Carlo Rolex Masters and Mutua Madrid Open losing to Murray and Djokovic respectively.
At the Internazionali BNL d'Italia in Rome, Raonic lost to Kyrgios in straight sets and his clay court season culminated in a shock fourth round defeat to Spaniard Albert Ramos-Vinolas in straight sets.
The grass court season was a successful one for the Canadian as he reached the final of the Aegon Championships and his first Grand Slam final at Wimbledon losing to Andy Murray in both.
Raonic had his back against the wall in his match with seven-time Wimbledon champion Federer in the semifinals in a rematch of their encounter two years ago, but the Canadian flipped the script and saved break points in crucial points of the match and he came back from two sets to one down to win the match.
The former world number four would come back from two sets to love down for the first time in his career against David Goffin in the fourth round.
Lu's notable results
The 32-year-old had a six-month injury layoff as he suffered an elbow injury which required surgery and the former world number 33 has reached one singles final on the ATP World Tour in his career but predominately has found success on the Challenger tour.
Lu's first match back on the ATP World Tour was a tough assignment as he was the first victim of Novak Djokovic at the French Open who went on to win the title and he suffered a 6-4, 6-1, 6-1 defeat but played some good clay court tennis throughout the first set against the Serb.
The second main tour event that Lu participated in was at Wimbledon and he recorded his first tour win of the year against Alexander Kudryavtsev but again he lost to the eventual champion Andy Murray in the second round despite going an early break up in the first set.
For the third tournament in a row, Lu lost to the eventual champion of the event and it was to Gael Monfils at the Citi Open in Washington.
Their history
Raonic and Lu have played each other twice and the Canadian leads their head-to-head 2-0.
Their first meeting was in Johannesburg which Raonic won 6-3, 6-3 and their second meeting was at the Monte Carlo Rolex Masters in 2014 on clay which Raonic won 6-7, 6-2, 6-1.
Who wins?
The Canadian number one will be raring to go as this will be his first match since Wimbledon and the crowd in Toronto will be firmly behind him.
Raonic cannot let his emotions take over in this match with Lu as Lu is more than capable of producing an upset.
Once Raonic settles down in the match, his big serve will pose a problem for Lu to return and the Canadian has improved his net game due to John McEnroe becoming a part of his coaching team.
Lu has defeated Andy Murray before in the past and Lu has a good serve himself which could bail him out of trouble, he is a good returner in his own right but Raonic's serve is a different kettle of fish to return.
Being drawn in the top half of the draw he has a possible meeting in the semifinals with three-time champion Novak Djokovic and since he has beaten Federer twice this year and has pushed Murray in Melbourne and at Queen's he will feel confident playing the world number one in Canada.
The winner of this match will play American qualifier Jared Donaldson or Fabio Fognini, who won the title in Umag last week in the third round.
This match kick-offs the night session taking place not before 6:30pm on Centre Court and expect a packed crowd to be in attendance.
Prediction: Raonic in straight sets.
