Look at your wagon wheels and see where you were hitting the ball but, most importantly, you need to practice proper cricket shots. Make your net sessions fun but, make sure that they are quality as well - and yes, you can have fun and play proper cricket shots. Get the bowlers to set their imaginery field and then play shots as if you were in the middle - if you don't keep working at your game your muscle memory will revert to the shots it knows - and these will get you out when you play at a higher level.
All in all, you did really well to bowl/field the full 50 overs on a really hot day. However, we were definitely down on the performances at Wanganui where our strength was our teamwork. When we had our backs against the wall (7 wickets down), I spoke about cheering every run - all I could hear in the middle was the support from the parents. We must pull together when times are tough and really work as a team let's make a concerted effort next week to really focus on supporting each other.
