Fantasy Baseball Player News

Henry Bolte, OF, Athletics

Athletics outfielder Henry Bolte has been terrific ever since being promoted to the majors for his MLB debut. Across nine big-league games, he's slashing .310/.382/.345 with an 11.8% walk rate, a 20.6% strikeout rate, and 108 wRC+. He hasn't launched a home run in the majors yet, but we knew that he didn't have a ton of power even before he was called up. He's made up for it by stealing three bases, as he continues to show off his game-changing speed.

Bolte's base-stealing upside gives him a clear path to plenty of production in fantasy baseball. He's still available in 89% of fantasy baseball leagues, and he ranks as the #62 outfielder in RotoBaller's latest rankings for the 2026 season. Bolte represents a speed-centric waiver wire target as we approach the end of May.

Ian Happ, OF, Chicago Cubs

Chicago Cubs outfielder Ian Happ is out of the lineup for Sunday's game against the Houston Astros for a "mental breather." Cubs manager Craig Counsell said, "he told him to take Saturday off completely, and Sunday, he's been hitting and doing other typical pregame work. The 31-year-old has struggled mightily over his last six games, slashing .042/.115/.083 with 14 strikeouts across 26 plate appearances. Overall, Happ had been solid, slashing .214/.350/.429 with 10 home runs, 20 RBI, 35 runs, and two stolen bases through 220 plate appearances.

His walk BB% has increased from 13.1% last season to 16.4%, while his K% has ballooned from 22.8% to 33.2%. Although there is cause for some concern, fantasy managers should continue to hold onto Happ as he works his way back through his slump. Happ is expected to return to the Cubs lineup for Monday's contest against the Pittsburgh Pirates.

Christian Walker, 1B, Houston Astros

Houston Astros first baseman Christian Walker was the team's offense in their 3-0 shutout victory over the Chicago Cubs at Wrigley Field on Saturday, going a perfect 3-for-3 at the plate with two home runs, three RBI, and a walk to raise his season average to .266 and his OPS to .861. Walker hit a two-run home run to get things going in the first frame and later hit a solo homer in the fourth inning for all the runs that Houston would need to finish off the Cubbies.

The 35-year-old reached base in all four of his plate appearances on the day. Despite the two-homer performance, Walker has hit just .164 (9-for-55) with four home runs, a double, seven RBI, six runs scored, four walks, and 14 strikeouts in his last 15 games, dating back to May 8. On the year, the right-handed power hitter is slashing .266/.340/.521 with an .860 OPS, 13 long balls, 34 RBI, and 30 runs scored in his 192 at-bats. Hopefully, his two-homer outing on Saturday will get him back on track offensively for an Astros team that really needs him more than ever.
