As pointed out after the excerpt ran:
He managed the 1976 team to an American League championship and two World Series victories in a row.
This is incorrect and really badly worded. Elsewhere in the chapter I think the order/secession is clearer. More properly, this should be
He managed the 1976 to team an American League Championship, the 1977 team won the World Series. You might also give him some credit for the 1978 team: Martin was fired mid-season, and the team ended up winning a World Series with Bob Lemon at the helm.
I’d have to hunt through the copies to see where I introduced the error, but in one of the revisions, I was looking at Martin’s managerial summary page while re-writing, and screwed up.
