In the 1980's, I used to follow the minor league players in the Red Sox system much more closely. One of the more hyped up amateur drafts for the Red Sox during that period was the 1982 draft in which the Red Sox had 3 first round picks and 2 seconds as a result of the loss of free agents Frank Tanana, Joe Rudi, and Bill Campbell (all of whom were washed up by then anyway). The major league team was at a bit of a crossroads; Lynn and Fisk were gone, as were most of their starts from the powerhouse teams of the late 1970's. The Sox had some relatively barren drafts in the late 1970's, and many of their better prospects had already moved up to the big league club or were close.
Their first pick was the player for whom this board is named. Their 2nd pick was Bob Parkins, a pitcher that washed out in A ball. Their 3rd pick was a highly touted college slugger Jeff Ledbetter, a former Yankees and Expos draftee that went unsigned. The 4th pick was Kevin Romine. It was still a productive draft for the team, as it did produce Mike Greenwell (3rd round) and Jeff Sellers (8th). The point of this post, however, is not the draftees that washed out. Instead, it is the team's 6th round pick and third baseman Sam Nattile, a player Greenwell called the best hitter of that draft class.

He slugged to a 0.844 OPS in his AA year, no small feat given the spacious dimensions of New Britain's home ballpark, Beehive Field. His career stopped at that point as he never recovered from a huge drop off in his first and only season in AAA. Most AA players do not sniff the majors; those that do nearly always hit better than 0.200, unless your name is Marc Sullivan.
