Major Off Season Moves, Hockey Signs Five New Devils

May 3, 2022

TEMPE, Ariz. -- The Arizona State men's ice hockey staff went to work this offseason, signing five top-shelf transfers who will join the roster for the 2022-23 season. The group includes four forwards and a goaltender from Boston University, Northeastern, and Bemidji State. 

The forwards: Robert Mastrosimone, Lukas Sillinger, Ty Jackson, and Dylan Jackson combined for 86 total points in 2021-22. TJ Semptimphelter joins ASU's netminder group with a .937 save percentage in his rookie season at Northeastern. 

"The level of talent with this transfer group is off the charts," said head coach Greg Powers. "All five of these players could have gone anywhere they wanted, so we are thrilled and honored they chose to be Sun Devils. The best thing about all of them is they each have multiple years of eligibility which most of them will take at ASU. We're looking forward to opening up our new arena with such a talented group of players."
