Barry Eaton Ex-Leeds assistant coach on BBC Radio Leeds
Leeds are so hot down their left-hand side and Saints can't handle Lachie Miller, Ash Handley and Chris Hankinson. They are causing all sorts of problems.
They made an inroad down that left-hand side and then Brodie Croft found McDonnell and he shrugged off a couple of defenders and scored to the right of the posts.
When Leeds play like that Saints can't handle them.
In answer to my question - no, the game is back in Leeds' hands.
James McDonnell shows tremendous speed with his feet to weave his way to the line and frankly, he has no right to be scoring from where he picks up possession. Absolutely sensational stuff from the Leeds second row.
Jake Connor sends his kick through, in the aftermath.

That's a lucky try. You can be as world-class as you want. Morgan Knowles will tell you he planned to do that, he was going to tap it onto his right foot, grubber it in-goal and it all worked out to perfection.
You get good breaks and bad breaks - that's a good break. A lot of the time in play-off rugby league, with two high-quality teams, that's what it comes down to.
Chris Hankinson looks to run in at the corner in much the same manner as his first try but before he can get through, he's flung to the ground by no less than four St Helens players.

It was all St Helens in the opening 10 minutes but the whole momentum swing has gone back in Leeds' direction.
The difference between the two teams at the moment is synergy - it's people turning up and everybody knowing what their role is.
The halves are splitting the field perfectly for the Rhinos, everyone is fitting in seamlessly into their positions and they're keeping St Helens on the back foot and keeping the defence guessing.

Either side can win tonight. Leeds home advantage may tell. Winner to play KR, whose form has dipped recently. Good luck to both teams and let’s see a good contest.
