Finding the perfect addition to your Fantasy baseball team via the waiver wire is the key to winning in any Fantasy league, but if it were easy, anyone could do it. And if you're searching for a hitter to round out your Fantasy baseball lineup, you absolutely need to see what SportsLine's Fantasy expert Alex Chamberlain has to say.

Chamberlain is a 5-time Fantasy Sports Writers Association award finalist and was recognized as 2015's Newcomer of the Year and 2018's Fantasy Baseball Writer of the Year. He competes in Tout Wars and contributes (other) work online at RotoGraphs and in print in Lindy's Sports annual Fantasy Baseball magazines. Previous bylines include Baseball Prospectus and Rotoballer. If there's anybody who knows what it takes to win a league, it's him.

Now, he's done an in-depth analysis of the best hitters who are widely available entering Week 12. One we'll give away: Diamondbacks SS Nick Ahmed, who's available in 75 percent of CBS Sports Leagues.  

"It's probably time for us to stop ignoring Ahmed," Chamberlain said. "For a hot second, I had rostered him in a 15-team league as an injury replacement for Trea Turner -- and it wasn't a total loss! And Ahmed has continued to perform adequately enough to keep him on the mixed league radar for some time now. With four home runs, four stolen bases, and a .264/.321/.405 line through roughly two-fifths of a season, Ahmed's on pace for a double-digit power-speed season and enough runs and RBI to keep pace with other shortstop options."

Chamberlain has also identified which hitters you should target on waivers if you need a jolt for your squad, including an undervalued player who's poised for a breakout. Anyone who adds this player could hit it BIG.
