This girl has been running 2 miles, doing a dozen stadiums, weightlifting, cardio 5 days a week for about 6 weeks getting ready for softball season. If I did all that I'd be in super shape. It's really weird and got me stumped.
If she's doing all this and eating like a bird she in chronically under eating and could be doing real harm to her metabolism.
We have this screwed up notion that to lose weight one must starve themselves. It's not needed. Your daughter with that active a lifestyle should be eating 1500+ calories a day, especially being a teenager. I've lost 88 pounds eating more than that and am nowhere near that active.
Have her record what she eats for a week and evaluate from there. (There's apps to make it easier)
Your daughter doesn't look overweight in the photos you've posted but I understand an extra 25lb is uncomfortable.
