Fantasy baseball waivers and the acquisition of fantasy baseball free agents 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.

Do you need to add players to replace your fantasy baseball busts? Which players can you ignore? KFFL.com's Diamond Market series gives you the fantasy baseball tips and advice you need to sort through the masses quickly.

Key

Acquire - Add player (in most circumstances)

Watch - Track player; consider adding if trend continues

Pass - Do not add player (in most circumstances)

Catchers

Buster Posey, San Francisco Giants

Pick up a pocketful of Posey

The Giants plan to give Posey some extensive PT if and when the Giants are eliminated from postseason contention. The big-name prospect is just 1-for-3 in three spot-duty games.

Bengie Molina (hand) left Thursday's game early, meaning they may not wait long to install Posey there. Last year's Golden Spikes Award winner wasn't too bad in 115 combined farm games this year: .325-18-80 with 84 runs scored. Two-catcher fantasy owners should be more intrigued.

Starting pitchers

Homer Bailey, Cincinnati Reds

Has the light bulb come on for Bailey with his 2.67 September ERA? His 1.42 WHIP for the month says to be cautious, but his last three starts were lethal: 2.45 ERA, 18 1/3 innings, 14 K's and a 1.25 WHIP that is an improvement for the typically wild one.

Bailey lines up against the St. Louis Cardinals and Pittsburgh Pirates at home next week; he has pitched better at Great American Ball Park, with three straight quality starts there. Be wary of the Cards' upper-level road offense, but the Pirates appearance and his home performance make Bailey worth a two-start gamble for spot-start seekers.
