The Latest: Japan rises up rankings after upsetting Ireland

TOKYO (AP) — The Latest on Day 9 of the Rugby World Cup in Japan (all times local):

10:25 p.m.

Spirits were high and the ranking was rising. While fans were celebrating up and down the length of the country after the Rugby World Cup hosts upset Ireland 19-12, the sport's governing body revealed the result meant Japan's ranking would reach an all-time high.

Supporters were calling it the sequel to the so-called Miracle of Brighton, when Japan upset two-time World Cup champion South Africa in England in 2015 in the biggest upset in the tournament's history. This time, on home soil, Japan rallied from 12-3 down to beat Ireland in the shocker in Shizuoka. It also lifted Japan to a record high No. 8 in the World Rugby rankings.

Japan went close to reaching the last eight at the 2015 World Cup but just missed out. This time, reaching the quarterfinals is the goal, and Japan is leading Pool A with group games remaining against Samoa and Scotland.

Ireland started the tournament with the No. 1 ranking but lost top spot when defending champion New Zealand beat South Africa. The Irish have now slid to No. 4.

South Africa restored some order at the Rugby World Cup by putting away Namibia 57-3 in Toyota.

The Springboks' second string lineup was still a different level against the World Cup's lowest-ranked team in a Pool B game that was only a side story to Japan's shock win over Ireland hours earlier. That threw the tournament on its head and put Japan in ecstasy.

South Africa scored nine tries, five in the first half and four in the second. Hooker Bongi Mbonambi and winger Makazole Mapimpi had a pair each.

Namibia has never won a Rugby World Cup game and the gulf between the teams was clear — and big — despite them being southern African neighbors. Namibia also had players sin-binned in each half to make it much harder for itself.

South Africa is 31-3 up at halftime against Namibia and it doesn't look like there's any chance of another upset on Saturday at the Rugby World Cup.

Host Japan threw the tournament on its head a few hours earlier by beating Ireland, the No. 1-ranked team in the world at the start of the tournament.

In Toyota, the Springboks scored five tries in the first 40 minutes against the lowest ranked team at the World Cup. Namibia has never won a game at the World Cup.

Hooker Bongi Mbonambi scored two tries from rolling mauls and flanker Francois Louw scored one. Winger Makazole Mapimpi and center Lukhanyo Am also crossed.

After a rapid start, the South Africans were sloppy for a 10-minute period before Am scored right at the end of the half. Flyhalf Cliven Loubser kicked a penalty for Namibia's only points.
