AJ Burnett had statistically the worst season ever as a Yankee starter last season. Adam Dunn hit .159 and struck out in 36 percent of his at bats.

But who had the worst season in history? Both as a pitcher and as a batter?

Pitcher: My vote goes to John Coleman who pitched for Philadelphia in 1883. He went 12-48 with a 4.87 ERA giving up 772 hits in 538 innings. That year he led the league in hits surrendered, earned runs, losses, and home runs surrendered.

Batter: I would say either Bergen's .139 1 HR 15 RBI performance in 1909 or Rob Deer hitting .179 in 1991 and striking out in almost 40 percent of his at bats. Though he did hit 25 HRs.
