  • The 2023 Rugby World Cup is taking place in France from September 8 to October 28

Irish to defeat the Springboks?

South Africa is a 2.5-point favorite over Ireland on Saturday. While the two nations have never gone head-to-head in the Rugby World Cup before, the Irish defeated the Springboks 19-16 in a Test back in May 2022. Ireland won their first two matches against Romania and Tonga by a combined 117 points. Better yet, all their key players got through unscathed.

The reigning champions are coming off a 76-0 victory over a Romania, which followed a 18-3 win over Scotland. However, they will be missing fly-back Handre Pollard with a calf injury. Saturday’s main event in Paris will be a tight, gruesome affair, but we like the 2023 Six Nations champions to top the Springboks. Take Ireland to win outright at +122.

France vs Namibia

France is 64.5-point chalk on Thursday. After group stage wins over New Zealand and Uruguay, Les Bleus has Pool A all but wrapped up. Therefore, their first priority will be to stay healthy in their remaining games against Namibia and Italy. The French were already in cruise control in a 27-12 victory over Uruguay, not even coming close to covering the 57.5-point spread.

Namibia lost their opening match to Italy by 44 points before suffering a 68-point destruction to the Kiwis last Friday. However, maybe just maybe, they can cover the 64.5 points with France likely playing it a bit safer.

Wales vs Australia

Australia is a slight 1.5-point favorite on Sunday. After a 22-15 upset loss to Fiji, the Wallabies must beat Wales to avoid elimination at the group stages for the first time in the tournament’s history.

Wales currently leads Pool C following victories over Portugal and Fiji. However, the Welsh could still miss out on a fourth-consecutive World Cup quarter-final appearance with a loss.

Best Bet

While they’re just 2-5 versus the Aussies in the World Cup all time, Wales came away with a 29-25 win in Japan in 2019. Given how poorly the Wallabies have played under Eddie Jones of late, we like Wales to score the upset (+102).
