The 1912 WS was the high point of Yerkes's career. He drove in the winning run for
the Red Sox in Game One with a two-run seventh-inning single, and he scored the Series-winning
run in the tenth inning of Game Eight (Game Two had been a 6-6 tie). In that final
game, Yerkes drew a walk off Giants ace Christy Mathewson
two batters after outfielder
Fred Snodgrass's famous error, and later scored on Larry Gardner
's sacrifice fly.
That season, his first as Boston's regular second baseman (he'd been their shortstop
in 1911), he hit .252 with a career-high 73 runs. After three solid seasons with
Boston he jumped to the Federal League
in mid-1914 (while earning $3,500 a year with
the Red Sox) to make $6,500. He hit a career-high .288 for the 1915
He later managed in the minors and coached Yale's freshman team.
