Chapman made his Cubs debut Wednesday, coming on with a seven-run lead and striking out two in a perfect ninth against the White Sox.
The Cubs didn't need their new closer to preserve a tight one -- they just wanted to give him a chance to get his sea legs under him after Monday's trade, so they tossed him in on the back end of a blowout of their crosstown rivals. The transition to pitching in the NL Central won't be a hard one for Chapman, who spent six seasons with the Reds and should remain one of the top few closers in the game.
