Be sure to check all of our fantasy baseball lineup tools and resources:
Ryan O'Hearn, 1B/OF, Baltimore Orioles
21% rostered
In only three games this month, O'Hearn has totaled 12 bases, adding a double, two homers, and three RBI, bringing his season average to .306 and his OPS to .979. The 31-year-old crushed it across a three-game series against his former team, the Kansas City Royals, for whom he produced a -2.6 WAR in five seasons. O'Hearn was traded for cash to the Orioles in January 2023. He's made them pay since.

Perhaps O'Hearn's track record is why he's just 21% rostered. He's also on the wrong side of 30 and doesn't play every day. But his success in Baltimore has been noticeable. O'Hearn has accrued 4.1 WAR and slashed .278/.334/.465 with 36 homers in 279 games with the O's. He's just two HRs shy of matching his total with the Royals (38). So, what gives? What more does O'Hearn have to do to see an uptick in his rostered percentage?
Keep hitting homers, sure, but by now, fantasy managers should be familiar with O'Hearn's game. He's inconsistent; he'll have incredible offensive stretches followed by lackluster slumps. And at this point in O'Hearn's career, there's not much more to uncover about him as a ballplayer. He can supply you with the occasional hot streak, but he's not a long-term option. O'Hearn will regress to the mean eventually.
Kyle Stowers, OF, Miami Marlins
58% rostered

Jacob Wilson, SS, Athletics
47% rostered
The Athletics are employing a youth movement in Sacramento this year. Among the youngsters is 23-year-old Jacob Wilson, son of former major leaguer Jack Wilson. Jacob was the sixth overall pick of the A's in the 2023 draft and made his MLB debut in July 2024.

In the 239 PAs that have followed, Wilson has a career .302 BA and .342 OBP, with 13 walks to 16 strikeouts. However, only 13 of his 67 career hits have gone for extra bases. Wilson has six doubles, three homers, and 18 RBI this season, showing that perhaps he is on the upswing. It's important to remember that he's still under 25 and has just 62 big league games under his belt. He has plenty of time to develop his power stroke further.
Maybe his lack of power keeps fantasy managers from adding him. Wilson ranks 73rd and is 47% rostered. Still, his on-base skills are there, and he can be a serviceable piece to any lineup. Wilson certainly has long-term potential given his age and lack of MLB experience, leaving plenty of room for future growth.
Maikel Garcia, 2B/3B, Kansas City Royals
72% rostered
Players with a multi-homer game and 2 games with multiple stolen bases through their first 5 games played in any month in the modern era (since 1901).
