As we dive into Week 8 of the fantasy baseball season, it's time to sharpen your roster with some under-the-radar gems. Whether you're scrambling to cover an injury or simply hunting for a hot bat, these sleeper hitters—all rostered in less than 80 percent of CBS Sports leagues—could be your ticket to a winning week. Scott White breaks down the top 10 waiver-wire targets, offering a mix of upside and opportunity that might just surprise you.

First up, let's talk about the best hitter matchups to exploit this week. The Seattle Mariners, Arizona Diamondbacks, and Kansas City Royals are facing favorable pitching staffs, making their lineups prime targets for streaming. The Mariners take on the Astros at home and then head to San Diego, while the Diamondbacks travel to Texas and Colorado—both ballparks that can boost offensive numbers. The Royals, meanwhile, face the White Sox and Cardinals, two teams that have struggled to contain opposing bats.

Now, onto the sleeper hitters themselves. Jac Caglianone leads the pack, a dynamic talent who's been turning heads with his power and plate discipline. He's followed by Ryan Waldschmidt, whose speed and on-base skills make him a valuable asset in deeper leagues. Don't overlook the Athletics' matchup-heavy schedule against the Cardinals and Giants, or the Nationals' three-game set in Cincinnati, where the Great American Ball Park could spark some offensive fireworks.

On the flip side, be wary of tougher pitching matchups this week. The Padres face a tough road trip to Milwaukee and Seattle, while the Phillies head to Boston and Pittsburgh. The Astros have a split week with the Mariners and Rangers, and the Tigers take on the Mets and Blue Jays—both teams with solid arms. Plan accordingly, and remember: these sleeper picks are about finding value where others aren't looking.
