Highest first class score: about 785 (With Somerset v Essex)
Highest first class player score: 406 (off 433) (Scott Newman for Surrey v Kent)
Best bowling inns: 10-98 M Munday for Somerset v Surrey
Most runs season: M Wood 1934 for Somerset
Most Wickets season 112 M Munday for Somerset
Best OD score: 399/5
Best OD player score: D Hansen (gen) 200*
Partnerships (for Somerset to lazy to load Surrey game): 1-448 (M Wood, R Key), 2-409 (M Wood, J Hildreth), 3-363 (M Wood, P Collingwood), 4-287 (M Wood, L Allenby(gen)), 5-280 (M Wood, J Hildreth), 6-182 (G Vincent, R Keller(both gen)), 7-320 (N Kulasekara, T Ambrose), 8-201 (A Caddick, D Chester), 9-142 (T Ambrose, M Munday), 10-92 (J Anderson, J Hildreth)
L Allenby has got 10 double hundreds at his 31st, stopped playing that game though...
One game Munday had 9-62 but some stupid youth OS-allrounder decided to take the last wicket...
