This week’s ATP tennis action at Geneva and Lyon is now down to the fourth round stage and some of the big guns at both events get their campaigns underway today. At Geneva top-seed and defending champion Wawrinka faces Brazilian Dutra Silva for the first time, third seed Ramos-Vinolas faces Kuznetsov who leads the head-to-head 2-0 and fourth seed Isner faces qualifier Zverev and the American leads the head-to-head 2-1. Fifth seed Johnson faces Zeballos for the first time and compatriot and sixth seed Querrey plays qualifier Skugor and this is their first meeting. Fifth seed Steve Johnson (18/1) was on my short list this week and unfortunately I opted for Lorenzi at bigger odds, who lost to Anderson yesterday, but at the odds its worth siding with the American who is still available at 1/3 the odds a place of reaches the final at the weekend.

At Lyon fourth seed Kyrgios was the biggest casualty of the week so far losing against qualifier Kicker from Argentina yesterday as did seventh seed Coric against Basilashvili. Top-seed Raonic and second seed and home hope Tsonga get their campaigns underway today against Istomin and Berlocq respectively. Raonic leads the head-to-head against Istomin 3-0 and Tsonga won his only encounter against Berlocq. Third seed Berdych faces NextGen star and qualifier Chung, fifth seed and home hope Simon faces Britain’s Edmunds and the head-to-head stands at 1-1 and sixth seed Del Potro faces qualifier Elias for the first time.

From an outright betting perspective at Lyon I think the talented Baslashvili (14/1) is overpriced considering his form this year and because he’s already through to the quarter-finals and has the advantage of a day’s rest compared to the other players in the bottom half of the draw.
