Who was the first switch-hitter to get 100 hits from each side of the plate in a single season?

The first switch-hitter to do this was Garry Templeton in 1979. In order to reach 100 from the right side, he spent the last nine games batting exclusively right-handed. He finally reached the plateau on September 28, 1979 by rapping three hits against the New York Mets. Templeton finished the season with 211 hits in 150 games.
