• Catcher Welington Castillo had successful arthroscopic surgery on his right knee Monday to repair a partial meniscus tear. Castillo, who was the regular catcher for the first time in his career, will need four to six weeks to rehab, and is expected to be 100 percent by Spring Training.
• Including Monday's game, the Cubs have six games remaining against National League Central opponents, the Pirates and Cardinals, which will be tough. Chicago is 24-46 against teams in its division, the second-lowest winning percentage by any team against its own division. The Cubs finished 41-45 against teams outside their division.
