The Lady Griz initially recruited Sammy Fatkin out of high school, but she chose Arizona. Now, the 6-foot guard out of Snohomish, Washington, is transferring to UM.
"The appeal was to have a chance to be part of a rebuilding process and culture change," Fatkin said in a news release.
"I want to be more involved on the floor instead of just a guard who only contributes by shooting from the corner."
As a freshman at Arizona, Fatkin played in all but two games, averaging two points and 1.1 rebounds per game in her 11.8 minutes per game. She also averaged 55.6 percent shooting from the free throw line.
Fatkin had 11 points in a home loss to San Diego State and seven points and six rebounds in a road loss at Oregon State, a team that advanced to the Elite Eight.
Fatkin will have to sit next season, but she has three years of eligibility remaining.
"She stood out as a big guard who had the ball in her hands a lot. Another thing that stood out was that she always looked like she enjoyed playing so much," Lady Griz coach Shannon Schweyen said of recruiting Fatkin in high school.
"It was disappointing to lose her, but she is a great kid and was very honest with us in the recruiting process, so there weren't any bad feelings. We ended on great terms and wished her well. It was great to get her text message and get the clearance to talk to her again."
Fatkin will be one of five newcomers on next year's team, joining incoming freshmen Jordyn Schweyen and Kylie Frohlich of Missoula, Katie Mayhue of Albany, Oregon, and Carmen Gfeller of Colfax, Washington.
