Top 2021 Fantasy baseball sleepers

One of the 2021 Fantasy baseball sleepers the model is all over: Marlins second baseman Jon Berti. The 31-year-old didn't make his Major League debut until 2018 with the Blue Jays, but he's carved out an important role with the Marlins thanks to a solid plate approach and terrific speed.

Berti has posted a .362 OBP over 376 plate appearances with Miami over the last two seasons and stolen 26 bases. Berti has 28 extra-base hits during that span as well, while his 15.4 percent walk rate in 2020 indicates he has a strong feel for the strike zone. That's why the model ranks him ahead of players Tommy La Stella and Keston Hiura, who are being drafted two rounds earlier on average in standard CBS Sports Fantasy baseball leagues.

Top 2021 Fantasy baseball breakouts

One of the 2021 Fantasy baseball breakouts the model is all over: Rangers starting pitcher Dane Dunning. The former first-round pick of the Nationals and top-100 prospect for the White Sox was the centerpiece of the return for Lance Lynn this offseason. He's now competing for a spot in Texas' starting rotation to break camp.

Dunning made his Major League last season after the White Sox ran into pitching depth issues and went 2-0 with a 3.97 ERA and 35 strikeouts in 34 innings. Dunning locates five pitches well and generated whiff rates of 30 percent or higher with his slider (43.5), four-seam fastball (34.6) and changeup (30.8) a year ago. That a big reason why the model lists him ahead of fellow starting pitchers like Matthew Boyd and James Paxton, who are going at least five rounds earlier on average.

Top 2021 Fantasy baseball busts

One of the 2021 Fantasy baseball busts the model is fading: Red Sox designated hitter J.D. Martinez. The 33-year-old had been one of the best hitters in baseball, but he struggled during an extremely disappointing 2020 campaign. Martinez has seen his barrel rate fall the last three seasons, while his average exit velocity is down 3.5 mph from 93 at its peak in 2018 to 89.5 last season.

That's led to a hard-hit contact rate that has dropped from 52.0 percent to 41.6 in just two years. Even if he can start producing, he doesn't have the same upside in a Red Sox lineup that isn't as intimidating as it once was. That's why the model ranks him behind designated hitters like Miguel Cabrera and Willie Calhoun, who aren't even being drafted, while Martinez is going in the 12th round on average.
