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)

Second basemen

Freddy Sanchez, San Francisco Giants

The club is hoping Sanchez (knee) can delay surgery until the offseason, but he hasn't played since Monday and has an unknown timetable to return. It's not worth waiting on him if you need games played, especially since his schedule will probably be spotty for the final week-plus.

Relief pitchers

Neftali Feliz, Texas Rangers

The righty tore up the bigs upon his call-up from Triple-A Oklahoma City. However, his fastball velocity has been down to between 92 and 94 mph recently, and the team can't figure out why. Texas insists he's healthy, but Feliz has allowed seven hits, six walks and five runs despite eight K's over his last 6 1/3 innings (five appearances).

Can they blame fatigue? Maybe he isn't getting enough time to loosen up. Either way, this sort of drop in velocity hurts his ability to help you as a fantasy reliever. How long will it take this unpolished youngster to make the adjustment? He has continued to record strikeouts, though, and if you're willing to gamble that he'll correct the other stuff, you can hang on. Be careful.
