Sally Roberts played the part of the Lone Ranger at the Greater Boston Tennis Championships on Saturday, and the only representative from the Radcliffe tennis team volleyed her way to a solid showing.

Playing in the number one singles bracket, she reached the semifinals before being ousted by Brenda Schaffer of Brandeis, 6-2, 6-1.

Before the Schaffer roadblock, Roberts had made short work of her first two opponents. In the first round she went' three sets against Heidi Ranz of U Mass, finishing strong to win, 6-3, 3-6, 6-1. Roberts' second match saw a "double bagel" job over Patty Finnegan of Holy Cross, 6-0, 6-0.

Impressive though it was, the sophomore's performance was not nearly enough to give Radcliffe the overall championship, which was won by Smith College.
