The early weeks of the MLB season are where sharp fantasy baseball managers separate themselves. Playing time shifts, small-sample breakouts, and overlooked prospects can swing leagues before the market fully reacts. This week’s fantasy baseball waiver wire discussion from FantasyPros highlighted four hitters who are widely available but trending up fast.

Fantasy Baseball Waiver Wire Pickups: Hitters to Add Now
Let’s break down why each name matters and how aggressively you should be targeting them.
Mark Vientos (1B – NYM)
Vientos is forcing his way back into relevance after a disappointing 2025. Through his first stretch of games, he’s been one of the hottest hitters in baseball, flashing a .400+ average with strong on-base and slugging numbers.
The key here isn’t just the production. It’s the opportunity.
With injuries opening up at-bats in the Mets lineup, Vientos is moving between first base, DH, and potentially even the outfield. That kind of positional flexibility keeps his bat in the lineup, which is all fantasy managers need right now.
There’s also some contextual optimism. Veteran presence in the lineup appears to be stabilizing things, and Vientos looks more comfortable attacking pitches early in counts.
He’s still available in a surprising number of leagues. If you need corner infield help or just want to ride a hot bat, this is a priority add.
Cam Smith (RF – HOU)
Smith might be the most polarizing name on this list, but the upside is undeniable.
The surface stats jump off the page. Power, speed, and a strong batting average are all showing up early. Under the hood, the metrics are just as encouraging. His hard-hit rate and barrel rate both point to legitimate skill growth, not just luck.
The biggest development is improved bat speed. That’s translating into more consistent damage on fastballs, which he’s punishing right now.
There is a catch. Pitchers will adjust.
So far, Smith has done most of his damage against fastballs, with limited success against breaking and off-speed pitches. That’s the next test. If he adapts, you’re looking at a potential breakout player who becomes a season-long hold.
At his current availability, he’s a classic upside add. In competitive leagues, he probably won’t last much longer on waivers.
Brady House (3B – WAS)
House is quietly putting together one of the more interesting early-season profiles among widely available hitters.
The former top prospect is locked into everyday playing time, which is half the battle in fantasy. The early results include a strong slash line with a mix of power and run production.
There are still flaws. Strikeouts will be part of his game, and he’s unlikely to maintain this level of production over a full season. But the minor league track record supports a solid power baseline.
Think of House as a realistic 20-homer bat with steady volume at a thin position.
In deeper leagues, that plays. In standard formats, he’s a strong bench add with the potential to become a regular starter if the growth continues.
TJ Rumfield (1B – COL)
Rumfield is the deepest name here, but also one of the most intriguing.
Any time you get a hitter with regular at-bats in Colorado, you pay attention. But this isn’t just a Coors Field bump story.
Rumfield is doing a few things extremely well:
- He’s getting the ball in the air consistently
- He’s pulling the ball at a high rate
- He’s limiting strikeouts while maintaining solid plate discipline
That combination is a strong foundation for power production, even if the raw exit velocity metrics aren’t elite.
The plate skills stand out the most. A low strikeout rate paired with a double-digit walk rate gives him a stable floor, which is rare for widely available power hitters.
In 12-team and deeper leagues, he’s absolutely worth a pickup. The path to 20-25 home runs is there, especially in that home park.
Fantasy Baseball Takeaways
- Mark Vientos is a priority add thanks to increased playing time and early production. Ride the hot streak while the role is secure.
- Cam Smith offers the highest upside. Add now before pitchers adjust, and reassess once the league counters.
