Leach has bowled nicely. I don't know if he has an arm ball, but because he hasn't got that one that skids on, he needs to use the crease more as his release point is the same for every ball. Just change it by six or seven inches as otherwise the batsman can line you up. His control's been good, he does err on the side of bowling slightly full, but when he gets a bit more confidence at this level he'll be in business. He's impressed me.
