Finding fantasy sleepers at the season’s beginning is straightforward; however, identifying them mid-season presents a greater challenge due to fewer uncertainties in playing time. Most of the intriguing prospects have confirmed their capabilities by now, either living up to expectations or disappointing.

As we assess the mid-season landscape, it’s crucial to highlight some players who might excel in the latter part of the 2025 MLB season. Here are seven individuals that could significantly increase their value moving forward.

Second-half Sleepers

• Denzel Clarke, OF, Athletics – Clarke is touted for his elite defensive skills, currently ranking as one of the best defensive outfielders in the league, based on his fielding metrics. He’s demonstrated promising abilities at the plate as well, giving hope for improvement despite a high strikeout rate.

• Kyle Teel, C, White Sox – While Teel has held his ground in MLB, his performance needs an uptick in offensive production to make a real impact. His minor league statistics suggest a strong potential to thrive as he continues to adapt.

• Christian Moore, 2B, Angels – Moore is currently on the injured list but showed flashes of power and a patient approach at the plate that should help him bounce back as the season continues.

• Brice Matthews, SS, Astros – Matthews is pushing for playing time amid team changes, presenting an opportunity to showcase his notable minor league abilities.

• Zebby Matthews, SP, Twins – His strikeout rate suggests a high ceiling, and he’s expected to rejoin the rotation shortly after a successful rehab.

• David Festa, SP, Twins – Festa’s transition to a sinker presents an intriguing matchup opportunity, and his underlying pitch selection indicates potential for improvement.

• Reid Detmers, RP, Angels – With the team potentially shifting pain points, Detmers could step into a closing role if opportunities arise, given his recent strong performances.

• Ronny Henriquez, RP, Marlins – With a rate of swing-and-miss pitches across his arsenal, Henriquez has an opportunity to become the team’s closer and excel in that role.
