I have been offered Mark Mulder for Kevin Mench. I have a fairly deep outfield with Bay, Sizemore, Carlos Lee, Kearns and Granderson. I also have Griffey and Huff coming off the DL. I could use another starter. Is this good value for Mench? - Mark Legge, Boston, MA

B.F.: Mulder's average draft position in CBS SportsLine leagues was No. 105, while Mench's was No. 176. That is proof that you are selling high and buying low -- always a good strategy in Fantasy play. Mulder is a consistent winner on a good team and is steady enough to start on any Fantasy staff. It seems that you are stacked in the outfield so go ahead and make the trade before Mench comes back to earth.

Which of these soon to be call-ups are the next great pitcher to have on your Fantasy team? Who will be up first? Anthony Reyes, Jered Weaver, Cole Hamels, Rich Hill? - Davis Eddie, Carol Stream, IL

B.F.: Well, this is a very good question and you clearly know your prospects. All four of these young arms should be owned in most leagues and are studs in keeper leagues that allow you to stash minor leaguers.

As for this season, Hill is getting the call and will take the mound on Thursday at Arizona. That makes him the best option, at least for the short-term. If he pitches extremely well, he could stick around and steal Angel Guzman or Sean Marshall's rotation spot. Now, rumors are swirling that Weaver could get the call as early as this weekend and, if that's the case, pick him up in all leagues. He has the most long-term potential and pitches for a team that will score some runs. Weaver has 50 Ks and only six walks in 35 innings for Triple-A Salt Lake. If those numbers don't indicate a future stud, what does? If the rumors are true, and Weaver gets the call, he becomes a better option than Hill even for the short-term.

Hamels recently tossed a two-hitter for Triple-A Wilkes-Barre and could replace Ryan Madson in the Phillies rotation anytime now. This would solve two issues for the Phillies, upgrading the rotation while improving the bullpen by using Madson in a relief role. Sounds like a good idea, right? He's dominated at every level and the only thing keeping Hamels below Weaver on my stud-to-be list is his lengthy history of injuries.

Reyes is the least intriguing at this point, but he's still someone that Fantasy owners should be well aware of. He'll be up eventually and has the command to win 13-15 games in a full season with St. Louis.

What do you make of Carlos Zambrano, Barry Zito and Oliver Perez? I have all three of these guys on my team and all they have done is disappoint. What should I do with these guys? - Joe Ioia, Gainesville, FL

B.F.: Zambrano should be fine. I wouldn’t be too worried about him, all you can do is leave him in your lineup and hope that he comes around. One thing that does concern me is that he's thrown 200-plus innings in three consecutive years, so maybe all that work is starting to have an affect on his young arm. I doubt it, so don't get too nervous. Zito is, and always has been, a headache for owners in the month of April. He's a slow starter and should come around soon. Be patient, and enjoy his production when he gets hot -- which should be fairly soon.

Perez is a different story altogether. He looks awful and his own manager seems to have lost confidence. I wouldn't recommend him in any Fantasy league until he strings together a few nice starts in a row. He's been so bad that he may end up getting sent to the minors to straighten himself out if he can't do it at the big-league level in the near future. If an owner in your league still believes in him, go ahead and trade him for someone that you can use.

Is it time to drop Bartolo Colon for another pitcher? When and if he comes back, just how effective will he be? He’s just taking up space on my roster right now. - Andrew Harver, Richmond, VA

B.F.: It's way too early to drop the reigning Cy Young award winner. Be patient. He'll be back in a few weeks and you won't want him winning 15-plus games for someone else in your league.

I have both Jason Bay and Manny Ramirez, who have not quite had the start I had hoped for. Meanwhile, my team is struggling for HR and RBI, which I was hoping these two guys would be leading my team. Part of my thought process is that Bay has no protection and will be pitched around. The other worry is that Manny just doesn't look like Manny. Should I look to trade these guys now or am I giving up too soon? - Neil Elsbury, Columbia, MO

B.F.: You're giving up too soon! Never sell low on your top players. Bay and Manny will finish with the monstrous numbers that you've come to expect from them. Sit back, be patient and let them get hot. It should happen any day now.
