Baseball America likes this guy more than anyone else (of the five top 100 prospect lists we track). In the order that they appear when all five are displayed...

John Sickels (under Custom in the software): No. 33

Baseball America (PR1): No. 27

Baseball HQ (PR2): No. 50.

Baseball Prospectus (PR3): No. 53

Rotowire (PR4): No. 146

Rototwire ranks the top 400 (we show the top 100 and select others). The order keeps changing, as it should. I wouldn't be at all surprised if Sheffield hasn't cracked the top 100 by now. I entered Rotowire's top 100 about a month ago.

In the current prospect rankings at Rotowire, he's only the sixth best on  the Mariners.

There may be better days ahead as the team treads water.

In the new Guide:

No. 19 Rookie of the Year Prospect: His pros-
pect stock rises and dips with the quality of his
pitches. At times he looks like an above average
left-hander with three plus offerings and at oth-
ers his stuff is disappointingly mediocre. The
lack of a reliable strikeout pitch along with less
than stellar command profiles him as more 
of an innings eater than a potential ace, and it
remains to be seen if he can avoid home runs
in the major leagues given his elevated fly ball
rate, but his opportunity for wins and innings
makes him worth watching. MARINERS JDB

McLEOD PICK: His arrival in Seattle should
remove any doubt about opportunities. As a
late-round investment, he could return a solid
profit.
