A week of good or bad matchups can make all the difference in Fantasy baseball.

And before you make any kind of claim on the waiver wire or set any lineups for Week 11 (June 3-June 10), you need to see what Chris Towers has to say. As Senior Editor for Fantasy at CBS Sports, Towers is one of the most respected voices in the industry. If there's anybody who can spot an edge in a matchup or identify a player in position to break out, it's him.

For Week 10, Towers said the Padres had some of the best matchups of the week and recommended picking up Franmil Reyes, who was only owned in 31 percent of leagues. The result? Reyes homered in three straight games to begin the week, giving huge returns to anybody who followed Towers' advice.

Now, Towers has studied the upcoming schedule and is sharing his best and worst hitter matchups for Week 11 of Fantasy baseball. They'll help you figure out who to sit, start, add, and drop this week. 

One thing we can tell you for this week: Towers loves the matchups for Red Sox third baseman Rafael Devers.

"Devers has been a bit disappointing in his second year, surprisingly because he hasn't been able to hit righties well, sporting just a .721 OPS against them," Towers said. "However, his all-fields approach is still perfectly suited for Fenway Park, and the Red Sox lay all six of their games there in Week 11."

Towers has also identified a sleeper who gets a dream slate of pitching matchups this week. This hitter should return massive Fantasy numbers in multiple categories, and he might be on the waiver wire in your league right now.
