IN the last Premier Cricket game before the Christmas break, Rockingham-Mandurah and Mt Lawley both landed blows on day one.
But the Mariners may rue the last hour of play in first grade where the Hawks gained the upper hand.
At Lark Hill, captain Mitch Green elected to bat and after a couple of early wickets, Dane Ugle (26) and Tyler Robertson (24) righted the ship.
The Mariners appeared to be heading for a big total courtesy of a 91 run fifth-wicket partnership between first year players Damien Burrage and Brandon Burt.
Burrage struck his first Premier Cricket half century and top scored with 59 from 92 deliveries, an innings that included four boundaries and a six.
Burt struck 44 after a first game 80.
Rockingham-Mandurah squandered a position of strength and tumbled from 4-182 with Burrage and Burt at the crease, to 9-190, until Lachlan Pratt (23) and Kyle Gardiner (21 not out) pumped up the total to 239.
Mt Lawley were 1-18 when Pratt struck early but crashed their way to 1-118 in the last 25 overs before stumps which leaves the Mariners no option but to strike early and frequently in the first session this Saturday.
