This the second game in which I have watched Keagan Rothrock of Florida. It's pretty clear to me that she uses the fatty grip on all her pitches. She throws the bullet rise (with a touch of backspin) a lot. All the strikeouts and significant contact where they slo-mo replay the pitch have the same spin, if there is a different spin it's too subtle for me to detect on TV. She does throw a pitch with a dipping trajectory but I haven't seen a replay of it.
