Despite a defeat at top-of-the-table Highfield Rangers, Egerton Park Seconds produced an outstanding performance with only 10 men.
Batting first on a lively wicket, Tyler and Bates started watchfully as the new ball popped and seamed about.
But after drinks, the visitors started to dominate the attack and the opening partnership had reached 88 when Tyler fell for 57.
Bates was unlucky not to reach a deserved 50 as he fell 10 runs short, but Tom Mould (16) and the Burdett brothers, Dave (15) and Jamie (14) helped Park reach a very competitive 176-6 at tea.
The Park wasted no time in ripping out Highfield openers and had the hosts struggling at 17-3.
The visitors kept on applying the pressure with great fielding and the outstanding bowling of Rivers who finished with five wickets for 42 runs in a 12-over spell.
They were backed up by the two 14-year-olds Josh O’Neil and Jack Simons, but despite the team’s great pressure, Highfield managed to get over the line for the loss of six wickets.
