quite simple: install PlayerEditor and modify the TeamAndPlayerInfo.bag by dropping the "Speed" attribute for the players. I have set them high since it makes batting a tad more difficult (frankly, not too much) and a bit more realistic (again these were my preferences, you're obviously free to change them)
btw, which difficulty are you playing? I usually play on County (not Test)
