The Asian swing is officially underway with a pair of 250s in China, and Hangzhou has already thrown up some entertaining tennis through the first few days. Day 4 steps things up a notch with top seed Daniil Medvedev entering the draw and looking to get his season back on track after a rough stretch that included a disappointing US Open.

Quentin Halys vs Roman Safiullin

These two have split their previous meetings one apiece, and that perfectly reflects how tight this match is likely to be. Halys sits considerably higher in the rankings but that numerical gap flatters him a little when you actually watch both players perform on court. Safiullin is a deeply inconsistent character, capable of looking world class one week and completely anonymous the next, but on his better days he can genuinely trouble anyone on the tour.

Given how unpredictable Safiullin can be, I would not be surprised if this one swings in either direction, but I think he edges it in a tight three setter. His ceiling feels slightly higher on fast hard courts and if he shows up ready to compete, he has enough to get over the line.

PredictionSafiullin wins in three sets

Yunchaokete Bu vs Kamil Majchrzak

These two have not faced each other before, so there is no head to head record to lean on. Majchrzak has genuinely had a career best season and his run to a first ATP title in Den Bosch in June was outstanding, but his form has cooled significantly since then and he has not been able to sustain that level going into the summer.

Bu, meanwhile, is riding a real wave of confidence after pulling off a stunning win over Rafael Jodar in the first round at Flushing Meadows. Playing in front of a home crowd in China is a genuine advantage and with momentum behind him, I think Bu uses this week to build something meaningful. He is the pick here.

PredictionBu wins in three sets

Chak Lam Coleman Wong vs Adolfo Daniel Vallejo

Vallejo currently holds the higher ranking but his recent form has been poor, and form matters far more than ranking position when you are trying to call individual matches at this level. Wong by contrast has been playing some genuinely sharp tennis and is a player who thrives on the faster hard court surfaces that Hangzhou provides.

The surface advantage combined with Wong being in considerably better form right now makes this look like a solid opportunity for him to come through. It may be closer than it looks on paper given Vallejo’s ranking, but I expect Wong to be too good on the day and take it without dropping a set.

PredictionWong wins in two sets

Daniil Medvedev vs Valentin Royer

These two have never met before, so Medvedev goes in without any specific tactical baggage to deal with from previous encounters. That said, the bigger story here is where Medvedev’s head is at after a season that has fallen well short of his own standards. Despite sitting around the world number six mark, he has not made a single deep Slam run this year, and watching Alexander Zverev win two Grand Slams in the meantime will not have been easy to stomach for someone with Medvedev’s competitive drive.

There is actually a genuine historical reason to be optimistic about his prospects over the next few weeks. It was during the Asian swing last year that Medvedev began rediscovering his best tennis and put together a run of results that rebuilt his confidence entirely. He loves these quick indoor hard court conditions and has a serious comfort level in this part of the world. Royer simply does not have the tools to trouble him at anywhere near full fitness and focus. Medvedev should come through this opener with something to spare.
