Cheek hit 209 and Blackman an unbeaten 204, the pair sharing a massive record 365-run second wicket partnership as sixes and fours flew all around the sunbaked Steephill bowl.
Cheek’s 209 contained nine sixes and 26 fours, Blackman clearing the boundary rope 11 times, in addition to hitting 22 fours. The pair came together with the score at 68 after opener Mark Fletcher had been dismissed for 19.
In all, Ventnor clobbered 20 maximums and 51 fours in their 45-over innings – Emsworth using seven bowlers in a desperate and unsuccessful attempt to stem the run tide.
Ryan Agnew’s five overs went for 92 runs, while new ball bowler George Falcon-Paterson conceded 93 off his curtailed six-over spell.
Toby Noyes took 5-16 as Emsworth were skittled for 85, leaving Ventnor winners by a mammoth 365-run margin.
Ironically, Shrewton's former Surrey & Warwickshire player Rikki Clarke outscored both Blackman and Cheek with 210 against Division 1 visitors Alton II. Ventnor's 462-2 was second highest HL total behind RAMs 481-4.
