The problem with the bunt strategy is the assumption that rec players who are overmatched by 50 mph pitcher can simply decide to lay down one good bunt after another against this same pitcher. It's worth a try, but how well can they bunt? How much have they practiced it? If you think she's a great pitcher now, wait until she gets ahead 0-1 and 0-2 in the count because of feeble attempts at bunting. If you bunt, it's important that they do not chase bad pitches. Inexperienced bunters are very prone to doing this.
The other advice that I'd share is to take more chances on the bases, especially w/ 2 outs. If you don't expect to get many hits, then you have to find other ways to advance base-runners. One of the biggest mistakes in rec ball (or any high-scoring game) is being too aggressive on the bases because the defense or the pitcher usually gives you the extra base if you're just patient. But against a dominant pitcher, you might need to go for it. What you don't want to happen is to have a ground ball move a runner from 2nd to 3rd for the second out when she could have been at third and scored on that grounder. Your base-runners have to take advantage of every misstep by their defense.
