IMO, she is lifting the shoulder prior to release. As she enters the release phase of the pitch, her pitching arm is noticeably away from the hip ( a indicator of the shoulder being tensed or contracted) and other pitchs her shoulder is lifting before she gets to the release. From what I see, she should be experiencing soreness in her trapezoid muscle as well as her deltoid because the shoulder is tense entering and throughout the release. AS Jojo mentions in his post.
I do like the energy and enthusiasm she exhibits but if she will relax the shoulder she can throw just as well and probably have less high pitchs.
