American Martin Trainer was the leader in the clubhouse after a partially-completed second round of the Hewlett Packard Enterprise Houston Open.

Trainer shot his second straight five-under 65 to lead by a stroke from compatriot Kevin Tway, whose rounds of 67 and 64 took him to nine-under.

After long weather delays on day one, only around half the field had completed two rounds by Friday night.

Jason Kokrak sat third at eight-under after completing 11 unblemished holes of his second round in a superb six-under par, with Adam Long a further shot away after carding 66-67.

No Irish or UK player made the cut mark of one over, with Graeme McDowell, Shane Lowry, Seamus Power, Russell Knox, Ian Poulter, Martin Laird, Tyrrell Hatton, Danny Willett and Lee Westwood all missing out.

Lorwry carded a 73 to leave him one shot the wrong side, while McDowell (75) and Power (70) finished three over and five over respectively.
