she lost the final to Elizabeth Ryan for the second year running. After another defeat, in the semifinal of the New York State Championships to Mallory, and on the advice of her doctor, she withdrew from that year's U.S. Championships and returned to Berkeley. She did not play any tournaments for the remainder of the year and instead focused on her studies at Berkeley. Apart from those two losses, beginning with the 1923 U.S. Championships, Wills lost only five matches in three years: once to Lenglen, twice to Kathleen McKane Godfree, and twice to Elizabeth Ryan.
