Union College junior Marilena Karadimou did not lose a game in two second-singles matches this week for the Dutchwomen. The junior helped Union clinch its first Liberty League Tournament berth ever with a 6-0, 6-0 win over RIT's Gabby Donahue on Friday, then came back on Saturday and did the same to No. 25 Vassar's Macey Dowd, only Dowd's fourth dual-match loss of the season.
