PERSONAL: Born March 25, 2006 to Michelle and Robert Estes… Majoring in Kinesiology… Kailey enjoys watching shows like "YOU," "Meteor Garden," and "The Summer I Turned Pretty," and loves movies such as "No Hard Feelings," "The Half of It," and "White Chicks." Favorite artists include Falling in Reverse, SZA, and Eminem. Her favorite quote is from Robert Frost: "In three words, I can sum up everything I've learned about life. It goes on." Before games, she sticks to a superstition of starting her warm-up with her curveball. She looks up to Jenny Finch as her favorite pro player and supports the Oakland A’s as her favorite pro team. Kailey’s favorite book is "Ugly" by Robert Hoge, and her go-to pre-game song is "Laffy Taffy" by D4L.
