An 84 run partnership between Zen Malik and George Hargrave was the highlight for the 2XI as they were tested in the middle by the Sussex bowling attack on Day 2.
Having started the day 254/4 thanks to Zach Lion-Cachet scoring 111 on Day One, Sussex found themselves with a lead of 165 runs.
Alex Russell claimed his first wicket of the day as he beat the bat of Lion-Cachet, with some sharp work behind the stumps from Charles Oldershaw removing the opener for a well made 111.
Russell picked up the second shortly after, trapping Foreman LBW for 17 and leaving Sussex 296-6.
Ealham and Tear put on a 73 run partnership for the visitors before Ealham was bowled by Ethan Rice. Alex Russell, O’Connor and a run out made up the last three wickets, as Sussex were all out for 424, bringing the first innings lead to over 300.
Alex Russell finished with three wickets, George O’Connor and Freddie Heldreich took two apiece, with the other three wickets coming from Rice, Prideaux and a run out from Zen Malik.
Despite the loss of two early wickets, the 2XI came out in stronger fashion this time round, with opener George Hargrave posting a half century within 26 overs, coming from 82 balls, with seven 4s.
He was ably backed up by Zen Malik, who shared a stand of 84 with Hargrave before Hargrave was trapped LBW by Lenham on 64.
Malik continued his strong showing by bringing up his half century in the 35th over, striking nine 4s and one six.
Harry Broderick fell on for 0, leaving Charles Oldershaw and Malik at the crease. The pair saw the batting side through to the end of the day, with Malik finishing on 79 and Oldershaw on 16 and the 2XI on 194/4, still trailing by 119 runs.
