Mattingly described what has happened defensively over the past three days as weird (Kenley Jansen's blown save on Saturday), physical (Jerry Hairston's errors on Sunday) and mental (Monday's botched rundown play). He said physical mistakes happen and there is no need to worry too much unless the mental ones start piling up.
The Dodgers entered Tuesday having committed 66 errors this season, which was the fifth most in the Majors. That is a far cry from last season, when the team committed only 85 errors, which was the fifth best in baseball.
