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 top hitters who are widely available entering Week 14. One we'll give away: Marlins 1B/OF Garrett Cooper, who's available in nearly 60 percent of CBS Sports Leagues.  

"You probably knew next to nothing about Cooper before this season," Chamberlain said. "He's a journeyman 28-year-old rookie first baseman/outfielder who, after myriad injuries, has finally gotten a chance to prove his worth… Unfortunately, injuries sidelined him for much of the beginning of this season, too. That hasn't stopped him from mashing, hitting six home runs and a robust .324/.395/.518 through his first 157 PAs… He could hit another dozen home runs with a .270 average the rest of the way, which will suffice in 15-team formats."

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.
