Since the defense has only given up 2 runs, you can assume the pitcher has been pretty dominant but she walked the first batter of the last inning of the game which is a huge "no-no". I like the strategy to bunt R1 over to 2B, and have her be aggressive looking to go to 3rd, if possible. Worst case scenario, you have a runner on 2B with only 1 out and #2 and #3 batters are up.
Would you ever just have #2 - 4 just swing away with R1 at 1st base and hope to get a couple of base hits to win the game?
At 10U probably not, the older ages... stolen bases are hard to get so yes.
