We have to go way back for this one, as Buck Ewing joined the Giants in 1883, after 

A player with multiple defensive skills (he played at Catcher, Outfield, Second, and Third), Ewing began his career in the National League with Troy, where he played three seasons before the team folded, and he joined New York, the team where he became a star.  Along with his defensive versatility (though he was at his best as a Catcher), Ewing was a competent hitter, batting over .300 in six of his first seven years with New York.  

19^th Century Baseball was not a power game, but Triples and Stolen Bases were in vogue, and Ewing could deliver.  He was the league leader in Triples with 20 in 1894 and had 109 in total as a Giant.  Ewing stole 178 bases on the base paths for New York, an astonishing number for a Catcher.  Ewing was also a large part of the original version of the World Series, leading New York to titles in 1888 and 1889.  

After 1989, Ewing was one of many players who jumped to the Players League, but with that organization lasting only one year, he was back to the Giants, playing there three more years before he was traded to Cleveland.

In 1939 Ewing was elected into the Baseball Hall of Fame by the Old Timers Committee.
