The correct 1B mitt to get will ultimately come down to age and player preference. The Nokona Walnut Series: N80W First Base Mitt features a 13.00 inch pattern and might not be the best fit for a player with smaller hands. With our 100 day guarantee and the adjustable wrist strap that the Nokona Walnut Series: N80W First Base Mitt features even a player who is 5'4" with smaller hands can rest assured they are not going to be stuck with a mitt that does not fit to their liking.
Unfortunately the Nokona Buckaroo Series: SBM100K Softball First Base Mitt is a discontinued mitt. It would be tough to find this glove at a retailer. The Nokona Walnut Series: N80W First Base Mitt would be the most comparable model currently on the market.
For your 14 year old daughter I would recommend the Nokona Walnut Series (N80W) First Base Mitt if you prefer solid webbing.
