The Red Sox have a -47 run differential over their last 3 games, the worst over a 3-game span in the Modern Era (since 1900).
It's the 4th-worst run differential in MLB history and worst since the Louisville Colonels in 1894.
There are only two qualified starters with a worse ERA than Dallas Keuchel since the start of last year. He's working on a shutout against the Red Sox right now.
