Rugby World Cup 2015: Winners and Losers from Sunday's Three Games

The second Sunday of the Rugby World Cup featured three contests between Tier One teams and minnows, and the form book was not ripped up this time.

Australia, Scotland and Ireland all processed wins with maximum points to remain on course for the bigger tests to come.

Packed stadiums in Leeds, Birmingham and London witnessed plenty of tries and no shortage of endeavours from the underdogs, who continued the theme of holding their more illustrious opponents for the first half before the big boys clicked into gear.

The power of a strong subs bench is already becoming evident in this tournament.

Let's assess today's winners and losers.

Australia completed a routine hammering of Uruguay at Villa Park with left wing Drew Mitchell passing a significant milestone in the process.

The Toulon man scored twice against the South Americans to become the Wallabies' highest try scorer at World Cups, passing Chris Latham's mark of 11, per the Daily Star.

It's a record the former Waratahs man may have believed he would never hold, having left Australian shores to join the European champions.

But after the Australian Rugby Union relaxed its rules on selection of overseas players, both Mitchell and his Toulon colleague Matt Giteau found themselves back in the squad.

No one expected Romania to take anything other than heavy beatings from their fixtures against France and Ireland.

But asking them to play both sides in four days made an impossible task seem more like an exercise in meanness from the tournament schedulers.

Credit to the Oaks for fighting fatigue as well as a gulf in class to keep going to the death against Ireland.

The deserved their 79th minute try. And now they deserve a rest.

There was a whiff of another seismic World Cup shock at the halfway point of Scotland's meeting with the USA in Leeds. The Eagles were soaring, 13-6 up at the break.

But Scottish coach Vern Cotter moved quickly and decisively to snuff out any such possibility with the introduction of Edinburgh pair Alasdair Dickinson and WP Nel.

The props were brought on to sort out a creaking Scottish scrum and did that job effectively.

But they also added extra ball-carrying impetus, and Nel got on the score sheet with a typical prop's try from close range.

Scotland's strong second-half performance secured them maximum points against the USA, but the win may have come at a cost for Vern Cotter's men.

Second-row Grant Gilchrist departed on 19 minutes with a leg problem, and there was deeper concern later in the match when influential fly-half Finn Russell was helped from the field.

Russell appeared to injure his knee upon landing from an attempted charge down of a USA clearance.

He had looked in good touch for the Scots, dragging the Eagles defence out of shape to create a score, and he will be an important player for Scotland's decisive clash with South Africa next week.

News from the Scottish treatment room will be eagerly awaited by Cotter and his staff.

No player in the Irish squad was more in need of minutes on the field than prop Cian Healy.

It has been a long road back to fitness for the Leinster loosehead.

And after a cameo off the bench against Canada, Healy started his first Test since March and put in over 50 minutes against Romania.

It was an important, and successful, step back towards full match fitness for Ireland's first choice No. 1.

He made nine carries for 25 metres and put in five tackles, as well as anchoring a solid Irish scrum.
