Pascali again lost a long ball, this time from Stephen Craigan, to leave Murphy clear on goal, but Bell dived to his left to push away the Scotland Under-21 striker's effort.
Only 54 runs were scored from 80 balls as first Prior (33 off 37) top-edged into the covers, then Bell was lbw trying to push Botha for a single after his scoring rate had dipped to below a run a ball.
