Junior forward Zachary Senft scored one goal and assisted on another to help lead Case Western Reserve University to two home UAA wins over nationally ranked teams. He assisted on the only score in the Spartans’ 1-0 win over 23rd-ranked Washington University on Friday and broke a scoreless tie in the 55th minute as the Spartans handed top-ranked and previously unbeaten University of Chicago its first loss of the season on Sunday.
