Leinster player ratings: Lowe and Gibson-Park the stars

Leinster held on against a late Saints surge to book another Investec Champions Cup final spot.

It took a James Lowe hat-trick and five points from the boot of Ross Byrne to get them over the line.

Harlequins or Toulouse await in the final on 25 May in London.

Here's how we rated the players.

15. Ciarán Frawley – 7.5

Had lots of involvements and was solid under the high ball. A threat in attack, too, and kicked well. His reputation as a more than able deputy to the injured Hugo Keenan is enhanced. Stopped a penalty going into touch in the first half to stop Saints getting a foothold.

14. Jordan Larmour – 7

Continued his form in a high stakes battle. Eager to get on the ball, mixed up his runs and kicks well and defended like demon, his tackle on George Hendy with 10 minutes left lifted the crowd.

13. Robbie Henshaw – 7.5

Savage shift by the centre, carried hard into traffic and stood up in defence. Stopped numerous attacks in midfield and was in the mix forcing multiple Saints errors.

12. Jamie Osborne – 7.5

Superb showing by the centre. Has the ability to kick, pass and carry, which always kept the Saints guessing. Ran 58 metres with ball in hand, the most of any Leinster player. Also joint top tackler of the backs with nine.

11. James Lowe – 9

Even before he got the first of two early tries, Lowe was heavily involved, relishing taking the ball into contact and using his power to retain possession. Made three clean breaks from 14 runs; kicked and fielded well in GAA HQ.

10. Ross Byrne – 7

Marshalled his side with confidence and his two successful kicks were crucial in the end. Read the play well to pick up an intercept before Lowe's second. Will be disappointed with the missed penalty in the second half.

9. Jamison
