After an off-year for the men's water polo program as a sophomore when he had to play goalie for much of the season, senior Ethan Lewis has helped rebuild the CMS men's water polo program back into SCIAC Championship contenders over the last two years, as the Stags head into Friday night's home semifinal against Pomona-Pitzer (7 p.m., Axelrood Pool) as the tournament's No. 2 seed. As a Claremont McKenna student majoring in computer science at Harvey Mudd, he has also used his academic pursuits to help rebuild websites.
