The book is called "Under a Grapefruit Sun," with the subtitle "Red Sox Spring Training a Quarter Century Ago," and it's written by a gentleman named Dan Valenti, who gained access to Red Sox spring trainings in the early 1980s.
It's an interestingly put-together product. The first half features Valenti's written recollections. Some are great, like his interactions with Ted Williams. Others, like his ranting against modern-day baseball, not so much.
But the second half is spectacular. That's where you see Valenti's photos from his visits to Winter Haven, Fla. Really awesome stuff. There's Williams, and Jim Rice, and Roger Clemens, and many others.
And now I'll give my copy of the book to the first person who e-mails me - at email@example.com - with the correct answer to this question:
The two Red Sox managers during the period Valenti documented were Don Zimmer (Red Sox manager from 1976-80) and Ralph Houk (1981-84). Houk, who died earlier this year, began his managerial career with the Yankees, leading them from 1961 to 1963 and 1966 to 1973.
Zimmer unofficially concluded his managerial career with the Yankees. He served as the interim manager for the first 36 games of the 1999 season, while Joe Torre recovered from prostate cancer surgery. Alas, the Elias Sports Bureau has put those 36 games under Torre's record.
In any case, there are three other men who managed both the Yankees and the Red Sox. Name them.
--UPDATE, 1:16 p.m.: We have a winner! Blog regular Tim N. knew that Frank Chance, Bucky Harris and Joe McCarthy managed both the Yankees and the Red Sox.
