Any H2H information on Marcus/Liam ? I have a feeling but my memory isn't great that Liam may have the edge there.
Other way round, Phil: 4:3 to Marcus, though Liam won the last encounter (quarter-finals of the Knoxville Challenger in 2014). They've met only once on grass, the semi-finals of the Felixstowe Futures event the year before when Marcus won by 6-4 7-6(4).
I saw a pretty good 3 set futures SF between the two on Edinburgh clay in 2014 when overall Marcus just had more in his locker than Liam and had his measure fairly well before the end.
I hope that Liam gets the better of this latest encounter.
