Defending champions Glasgow secured a second sweeping win over Zebre in three weeks on Friday to guarantee a Guinness PRO12 play-off berth.

Glasgow, who triumphed 43-14 in Parma on April 8, led 35-10 at half-time, with tries by Leone Nakarawa, Adam Ashe, Glenn Bryce [two] and Taqele Naiyaravoro. And they pulled further clear after the interval.

Nakarawa completed his hat trick, and Greg Peterson, Ali Price and Duncan Weir all dotted down, with the latter kicking every conversion in a 70-10 rout.

The Zebre tries were scored by Kayle van Zyl and Tommaso Boni. The result, coupled with Connacht's surprise 22-21 defeat at Benetton Treviso, lifted the Warriors top of the table.

Connacht secured a maiden PRO12 semi-final place despite suffering defeat to Benetton Treviso following Jayden Hayward's dramatic last-minute penalty.

The Irish province, leading 21-19, were penalised on the half-way line and full-back Hayward made them pay, helping to lift Treviso off the bottom of the table.

Although the losing bonus point helped Connacht qualify for the top four for the first time since the competition changed format to home and away fixtures in 2003-04, the defeat hampers their hopes of a home semifinal tie.

Connacht, who host Glasgow Warriors in their final game, had not scored a try at the Stadio Comunale di Monigo since April 2013, but they soon ended that drought by crossing twice in the first 14 minutes.

Rory Parata spotted a gap and dived over in the seventh minute and then Fionn Carr latched on to a kick to double their advantage, with both scores converted by John Cooney.

But the hosts, who have lost the last five games and beaten Connacht only once since 2011, responded with tries from Luca Morisi and Braam Steyn in the space of five minutes to narrow the deficit to 14-12 at half-time.

A converted penalty try moved Treviso 19-14 ahead in the 46th minute and, after Peter Robb's 52nd-minute effort appeared to hand Connacht the win, Hayward denied them at the death.

Francis Saili's 76th-minute try sealed a vital 27-19 bonus-point win for Munster against Edinburgh to put them on the brink of Champions Cup qualification.

Anthony Foley's men triumphed in Cork to move back into the top six, going five points clear of the Scots, who have fallen to seventh place.

The hosts led 20-13 at half-time thanks to tries from Rory Scannell, Simon Zebo and Andrew Conway -- all in the same right corner -- with Jason Tovey responding with two penalties and a superb solo seven-pointer.

Penalties from Tovey and replacement Sam Hidalgo-Clyne were the only scores of a nervy second half until centre Saili was driven over for the clinching touchdown.
