The 2026 fantasy baseball season is officially underway, with the first full week of MLB action providing an initial, albeit small, sample size of player performance. While time will undoubtedly adjust these early valuations, it is crucial now to identify players who are rapidly rising or falling in fantasy rankings.

Early Risers: Players Seeing Stock Increase

Catchers and Infield Stars Shine

One player already exceeding expectations is Langeliers, who has posted impressive early numbers. He is currently batting .375 with 3 home runs and 6 RBI across just 16 at-bats. This strong output reinforces the hypothesis that Langeliers is a legitimate breakout candidate for 2026.

Elite Second Base Production

Jose Altuve remains a top fantasy asset, batting an excellent .412 with 2 home runs and 1 stolen base. Given his established talent, Altuve is firmly positioned as the 2B1 in current fantasy baseball rankings.

Following closely is Donovan, who is off to a scorching start for the Mariners, hitting .444 with 2 home runs, 4 RBI, and a stolen base. Playing within an elite offensive unit, Donovan currently sits as the 2B2 and has a strong chance to maintain his high ranking.

Rookie Sensation in the Outfield

DeLauter is emerging as an early frontrunner for the NL Rookie of the Year award. He has already launched 4 home runs, even while holding a .286 batting average. Consequently, his fantasy ownership percentage has surged past 72%.

Pitching Dominance

One pitcher made an immediate statement in his first outing, delivering 6 innings pitched, allowing only 3 hits, and striking out 10 batters. Many believe this pitcher is poised to contend for the Cy Young Award this season.

Another hurler provided excitement for his team, recording 5 innings pitched, surrendering just 1 hit, and striking out 8. This performance resulted in an outstanding WHIP of just 0.19.

Early Fallers: Players Experiencing Stock Decline

Struggling Hitters

One designated hitter is off to a sluggish start, currently batting just .176, placing him as the DH20 in fantasy baseball. Managers are advised not to panic, as better performance is widely anticipated in the near future.

Another player is struggling significantly at the plate, hitting only .143 through his first 4 starts, with no extra-base hits recorded. Furthermore, this player was involved in a notable fielding disaster on Opening Day.

A third struggling batter is currently 1-for-17 on the young season and has already struck out 5 times. As with the other struggling hitters, the season is still very young.

Pitchers Facing Early Hurdles

One starting pitcher is currently ranked as the second-worst starter through one outing, accumulating -17 fantasy points and an alarming 67.50 ERA across only 0.2 innings pitched. While this pitcher is expected to recover, the start was certainly concerning.

Another player known for volatility had a poor first start, giving up 4 earned runs across 4 innings pitched. While not disastrous, this performance gives fantasy managers pause regarding his immediate upside.

Finally, a Boston-based pitcher began the season poorly, allowing 4 earned runs on 7 hits over 4 innings, resulting in a loss on his record. This early struggle suggests that Suarez might face a regression season.
