Hampshire soon lost Prittipaul, who added three runs to his overnight total. His score of 152 beat by 1 run the previous highest score by a Hampshire batsman on his home debut, beating Denis Baldry's 151 in 1959.
With overcast conditions and the new ball Derbyshire's seam bowlers held the upper hand for the first hour. Mascarenhas took 19 balls to get off the mark, and Aymes pushed and prodded to 20 before he fell to an in swinger from Cassar and was bowled.
Warne joined Mascarenhas and upped the tempo to give Hampshire maximum batting points for the first time this season. In 17 over the pair struck three sixes into the adjoining flats and shared 85 runs. Warne was out attempting another big hit, and Mascarenhas joined him back in the pavilion caught behind off spinner Lian Wharton, just two balls before the lunch break.
