At first I wondered if Wolfram Alpha had some poorly scrubbed data or the Red Sox had a couple hard years in the last few decades. Then, after finding the New York Mets had the same chart, I figured it was time to consult a human to figure out what happened in 1981 and 1994. The answer: labor strikes. Alpha doesn't have the full array of baseball statistics that obsessive fans crave, but it's got a good start. This chart shows hits, RBIs, strikeouts, and other details. It's hard to dig into the data at this stage, though, for example picking a specific range of years. You can compare multiple teams, but some of the data in the chart falls by the wayside.
