My local paper did some research on the best-ever negative baseball nickname now that people are focusing on all the A-Rod* choices. They picked Dick Stuart with his nickname: "Dr. Strangeglove"
"In 1964 -- the year Stanley Kubrick's classic black comedy about nuclear war, "Dr. Strangelove," hit the movie theaters. In 1963 with the Red Sox, Stewart made a career-high and AL-leading 29 errors at first base, for a fielding percentage of .979, 11 points below the league average.
As you can see they spelled his last name wrong. Now how about a nickname for Lugo?
