Fantasy baseball waivers and discarded fantasy baseball players can make or break a season. You may have adjusted your fantasy baseball cheat sheets over and over during spring training. If your team remains the same after opening day, though, you will probably have trouble competing in your rotisserie baseball league.

When is it time to give up on your fantasy baseball sleepers? Which players are worth retaining? KFFL.com's Diamond Market series gives you the fantasy baseball tips and advice you need to sort through the masses quickly.

Key

Discard - Drop player (in most circumstances)

Stash - Hold player if roster space is available; consider dropping if trend continues

Hold - Do not drop player (in most circumstances)

Third basemen

Aramis Ramirez, Chicago Cubs

A-Ram be a-restin' a good bit

The masher will probably play "sparingly" the rest of the way, according to skipper Lou Piniella, as he continues to deal with shoulder issues. When A-Ram is in the lineup, you have to play him. Hang on to him if you can work around his rest days, and examine your backup plans and needs before cutting him.

Shallow mixed: Stash

Deep mixed: Stash

NL-only: Hold

Casey Blake, Los Angeles Dodgers

Blake (hamstring) received a platelet-rich injection and is aiming to come back Friday. If you can't wait that long for Blake, who has already missed seven straight games and isn't certain for that return date, feel free to make other plans.

Shallow mixed: Discard

Deep mixed: Discard

NL-only: Stash

Outfielders

Josh Hamilton, Texas Rangers

The Rangers will keep Hamilton (back) out for the remainder of the season, ending a bust campaign. He aims to be at full strength for Spring Training 2010.

Shallow mixed: Discard

Deep mixed: Discard

AL-only: Discard

Starting pitchers

Jered Weaver, Los Angeles Angels of Anaheim

Weaver will be skipped in his originally planned Wednesday start and probably won't pitch again this fantasy season. Before you drop him, follow the news to make sure he won't contribute another fantasy start.

Shallow mixed: Stash

Deep mixed: Stash

AL-only: Stash

Rick Porcello, Detroit Tigers

It doesn't look like the AL Rookie of the Year candidate will pitch again this season, with Monday's rainout shortening Porcello's rest for what was supposed to be a Saturday start. Manager Jim Leyland wants to be cautious with the rook. Their schedule could change, especially with them trying to hold off the Minnesota Twins in the AL Central race, but if you need help elsewhere, act sooner rather than later.

Shallow mixed: Stash

Deep mixed: Stash

AL-only: Stash
