Champ or Chump: Girls get there bats, lids and gloves close by. They line up to take a hit off of a coach or machine. They get one swing; if they hit it fair, they go to the back of the line. If they miss or hit foul, they are a 'chump'. They are out of the line-up, but get their gloves and head to the field. In the field they can earn 'redemption' by cleanly fielding 2 or 3 hits (you pick the number). If this is achieved, they can get back in the hitting line. The last person in line is the 'champ'. One note; when there are two batters left, if the first misses or fouls, they hang tight. If the last batter misses or fouls, the second to last gets another chance. This continues until one of them gets a hit. (this description makes it sound more complicated than it is... my girls always love it)
Longest ball: Kids line up with bats and lids. They get three hits. You mark the longest ball with a cone or coach. The one with the longest hit wins a blow-pop or bag of seeds.
Two base relay race: Split the girls into two even teams (if not even, the one with one less will have to pick someone to go twice). Line one team up at home and the other at second. Give each of the first girls in line a ball. The coach says go and each girl runs around the bases and when they reach there starting base, they hand the ball (baton) off to the next player who then takes off and repeats the pattern. The first team to have all their girls complete the circuit wins. (to keep it competitive, try to split the teams up with even speed).
Tennis ball soft ball: Play a game of softball with a tennis ball and no gloves. The girls love it because simple pop flys become a huge challenge and routine throws from second to first are no longer routine.
