We all have seen how many runs the Sox have allowed, due to poor defense that has not been called an error, such as failures to turn easy DPs, off line throws, throwing to the wrong guy, failure to make tricky plays and other botches, but look at just the Runs Allowed vs UnEarned Runs Allowed numbers for the top 10 teams in least Earned Runs allowed:
KCR 52 ER/ 52 Runs (No, this is not a typo!) NO unearned runs allowed!
BOS 56/81 (No, not a typo!) 25 Unearned runs allowed in 20 games!
NYM 57/73 (Pretty bad at 16 Unearned but not close to 25)
NYY 59/70 (11 UnER)
CLE 60/65 (Just 5)
DET 63/75 (12)
MIL 67/77 (10)
PHI 64/78 (14)
MIN 70/78 (8)
The CWS have 14 Unearned runs allowed. Nobody else comes close!
