Whitby 3rds suffered a 73-run defeat at Guisborough 3rds in their NYSD Sunday Division Two clash.

Jordan MacDonald added support with 29 from 47 balls, while Aron Calvert was the top Whitby bowler with 2-30.
MacDonald then served up a flurry of wickets with 5-58 as the hosts dismissed Whitby for 143 in 42.2 overs.
