Bulls

Evan Longoria - 3B - (Tampa Bay Rays):  Those who drafted him in anticipation of seeing results in May or June, you were rewarded early.  Longoria got the call thanks to Willy Aybar, and he has made himself immediately comfortable.  Longoria has reached base in his first four major league games, hit .333, and already cracked his first HR while hitting fifth in the Rays' lineup.  Longoria looks comfortable already, and if he continues to play well, it will be impossible for the Rays to send him back down.

Kevin Youkilis - 1B/3B - (Boston Red Sox):  Youkilis is simply steady, but with Mike Lowell currently on the shelf, the Red Sox are asking Youkilis to play more of a run-producing role in the fifth spot of the lineup.  He has responded, ranking among the league leaders with 11 RBI while also scoring 11 R.  Hitting .385 with a .435 OBP certainly helps, but Yoooouuukkkk has also hit six doubles, two triples, and a homer.  As long as Lowell's injured, Youkilis is a must-start, and his versatility on defense makes him a nice backup at those positions, or even a full-time starter that won't hurt you at 3B.

Rafael Betancourt - RP - (Cleveland Indians):  Finally!  Joe Borowski has been pitching through injury, and I would bet he did so because he did not want to lose his job to Betancourt.  Well, Borowski did not pitch well at all, he was placed on the DL, and now Betancourt gets a chance to close.  If things go well, look for Betancourt to keep the job, since Cleveland fans have been clamoring for this moment for a long time.

Runners-up Bulls:  Zack Greinke - SP - (Kansas City Royals); Manny Acosta - RP - (Atlanta Braves) [note that Rafael Soriano and Peter Moylan are both injured].

Bears

Eric Bedard - SP - (Seattle Mariners):  There is no doubt that, when healthy, Bedard is one of the best pitchers in the game, and his high strikeout totals make him an almost-elite pitcher.  The hangup?  His injury history.  Although his most recent injury is not arm-related, one has to be concerned about his fragility.  This injury is not one to make owners look to trade him, but he needs to be watched carefully for any signs of discomfort anywhere.

David Ortiz - 1B/DH - (Boston Red Sox):  Ortiz's power numbers were down last year because of knee problems, and in the first month of the season, it does not appear that the problems have resolved.  Ortiz simply looks awful at the plate, and the numbers he has produced are even worse (.113 AVG, 1 HR, 3 RBI).  Terry Francona has been saying that Ortiz needs a mental break, but it is looking more and more like Ortiz might need a physical break.

Prince Fielder - 1B - (Milwaukee Brewers):  Is it the vegetarian diet?  Fielder revealed in the offseason that he became a vegetarian and now shuns all meat.  The results so far?  Zero HR and six RBI.  That is not to say that his diet alone, or at all, is causing his lack of production, but Fielder has been a huge bust so far, especially since he was taken in the very high rounds of fantasy drafts this year.  It is safe to say that Fielder won't match his home run total of last year, but he needs to get on a hot streak soon if he wants to remain one of the top five or eight 1B in fantasy leagues.

Runners-up Bears: Jose Valverde - RP - (Houston Astros); Ubaldo Jimenez - SP - (Colorado Rockies)
