In 1960, the team's sixtieth and last season in Washington, Valdivielso was the Senators' most-used shortstop, starting in 92 games and playing a career-high 117 contests. But by late September he had lost his starting job to Zoilo Versalles, a 20-year-old fellow countryman; Versalles would hold down the Twins' starting shortstop job through 1967 and, as the American League's Most Valuable Player, lead the Twins to the 1965 pennant.
