Fantasy Baseball Player News

Byron Buxton, OF, Minnesota Twins

Minnesota Twins outfielder Byron Buxton had the 19th multi-homer game of his career in Wednesday's 9-5 loss to the visiting Miami Marlins at Target Field, and he's now up to 15 home runs on the year. Buxton finished the contest 2-for-4 at the plate out of the leadoff spot for the Twins with two solo home runs, a walk, and a strikeout to raise his season average to .260 and his OPS to .899.

The 32-year-old veteran and two-time All-Star has stayed healthy so far in 2026 and is up to 23 RBI, 33 runs scored, and four stolen bases in his first 40 games. Buxton has also added four stolen bases, but fantasy managers shouldn't be expecting him to reach the 20-steal mark for the second straight year. At this point in his career, Buxton is primarily a power asset at the top of Minnesota's batting order.

He has really started to heat up offensively, batting .298 with all 15 of his homers, 22 RBI, and four stolen bases in his last 26 games across 114 at-bats. Continue to ride the hot-hitting veteran in all fantasy formats.

Mickey Moniak, OF, Colorado Rockies

Colorado Rockies outfielder Mickey Moniak continues to be money for fantasy managers in his second season with the Rockies. The 28-year-old former first overall pick by the Philadelphia Phillies in 2016 continued to rake on Wednesday night in a 10-4 win over the Pittsburgh Pirates at PNC Park, going 3-for-5 at the plate with a three-run home run, a triple, five RBI, and a strikeout to raise his season average to .315 and his OPS to 1.051.

He finished a single shy of the cycle and blasted his 12th home run of the season off right-hander Mitch Keller in the fifth inning. Moniak is proving that last year's breakout in his first year in Colorado wasn't a fluke. He's now slashing .315/.358/.693 with 12 homers, 26 RBI, 12 runs scored, and a stolen base in 137 plate appearances across 35 games in 2026.

The crazy part is that he's rostered in under 70% of Yahoo leagues. Run to the waiver wire and pick him up immediately if he's still available in your league.
