Answer: Quilvio Veras
A typical glove first infielder of the late 90's, Veras spent seven seasons at the big league level. He never hit for much power, but his relatively high career OBP of .372 allowed him to amass 12.9 bWAR in his career.
Funny enough, the lack of power was so great that his career OBP was greater than his career slugging percentage of .362. I'm not sure many guys can lay claim to that.
