There are a lot of really good players available on the fantasy baseball waiver wire as we head into the ninth week of the season. How are we already approaching double digits, guys? HOW? Didn’t the Dodgers and Cubs just kick off the season yesterday? Man. Time flies when you’re having fun and crushing the competition in all your fantasy leagues. That’s what we’re trying to do with these additions on the fantasy baseball waiver wire. I absolutely love the pitching options available and how almost all of them are available in over 80% of Yahoo! Fantasy and ESPN fantasy baseball leagues. Let's dive into the adds.

 

 

Fantasy Baseball Waiver Wire Pitchers

Logan Henderson, SP, Milwaukee Brewers

ESPN: 6% / Yahoo: 21%

FAAB: 4-6%

Sometimes the shiny new toy breaks down way too easily but sometimes the new toy becomes a toy passed down to a younger brother or sister because of how great it is. Logan Henderson feels like the latter through his first two starts this year. Henderson isn’t a hard thrower, averaging 92.5 MPH on his fastball, but he locates it well and hammers his opponents with change ups. Nearly 90% of his pitches are fastballs and changeup and his changeup rates out as an ELITE pitch.

He’s made only two starts and his change sits at a 3.46 wCH/C, which, if qualified, would be NINTH in all of baseball. Some of the pitches with better changeups you may have heard of; Skubal, King, Peralta, Bubic.

Henderson’s SIERA sits at 2.00 SIERA, 2.31 xFIP, and 40% K-rate. The numbers likely normalize, but I’m excited about how good Henderson looks through two starts.

 

Will Warren, SP, New York Yankees

ESPN: 5% / Yahoo: 15%

FAAB: 6-8%

We’ll double down on Will Warren after he made the write-up last week. He’s been fantastic and some of the surface level numbers look worse than they should. Warren has a 27.9% K-rate, 45% GB, 3.47 SIERA, and 3.18 xFIP on the year.

Warren’s best attribute is his ability to miss bats. He’s notched five straight starts of at least five strikeouts and has leveled up in his last three punching out seven or more. He’s been missing bats and his next start comes against a Rangers offense without Corey Seager and ranks bottom-10 in basically every offensive category against right-handed pitching.

 

Ryan Weathers, SP, Miami Marlins

ESPN: 5% / Yahoo: 19%

FAAB: 7-9%

Things were trending towards not being a major league pitcher until Ryan Weathers turned a corner last season. He made his first start of the year this past week and Weathers was throwing…really hard. Below are Weathers average fastball velocity at the major league level:

  • 2021: 93.9 MPH
  • 2022: 93.5 MPH
  • 2023: 95.1 MPH
  • 2024: 95.9 MPH
  • 2025: 97.3 MPH

I understand that this year was one start, but he was throwing this hard in the minors during his rehab as well. He clocked 97.6 MPH at Triple-A this year across three starts. Weathers pitches in a good pitchers park, is throwing harder, and looked great in his debut against the Cubs. He’s absolutely worth looking at on the waiver wire.

 

Zebby Matthews, SP, Minnesota Twins

ESPN: 2% / Yahoo: 15%

FAAB: 8-10%

The time has come. Zebby Matthews' time has come. Matthews is being called up to make his season debut after mowing down his opponents at Triple-A. He’s pitched to a 1.93 ERA across 32.2 IP and has a 28.1% K-rate. He’s missed bats at every level he’s pitched at, including at the major league level last year notching a 24.3% K-rate. He didn’t have that much success as a major leaguer last year, but he did have a 3.78 SIERA, 4.05 xFIP, and .364 BABIP, all suggesting he was unlucky.

The Twins sent both David Festa and Simeon Woods Richardson to the minors, paving the way for Zebby Matthews at the major league level. The future is now for the young right-hander.

 

Jordan Romano, RP, Philadelphia Phillies

ESPN: 7% / Yahoo: 41%

FAAB: 4-6%

Don’t look now, but after a slow start, Jordan Romano has fired off six straight scoreless innings and has notched two straight saves for the Phillies. He’s also missing bats at an elite clip posting a 38.9% K-rate in May.

Romano’s surface level numbers are bad, but there’s a lot to like under the hood.

  • 8.22 ERA, 3.51 xERA
  • 4.80 FIP, 3.95 xFIP
  • 3.44 SIERA
  • 12.9% SwStr, up from 11.2% in 2024
  • 40% GB in ‘25, 27.9% GB in ‘24
  • 28.9% HH in ‘25, 34.1% in ‘24

Just check your waiver wire to see if he was dropped because he’s clearly retaken over the role as the Phillies closer with how shaky their bullpen has been.

 

 

 

Fantasy Baseball Waiver Wire Infielders

Hyeseong Kim, 2B/SS, Los Angeles Dodgers

ESPN: 11% / Yahoo: 25%

FAAB: 2-4%

The start Hyeseong Kim has gotten off to is unsustainable, but boy he’s staking his claim at much more playing time moving forward. He’s an ad now, worry about things later waiver wire addition because eventually Tommy Edman is going to return. The good thing for Kim is his ability to play multiple positions.

Before being called up, Kim played: 

  • 9 games at 2B
  • 12 games at SS
  • 10 games in OF

Since being called up:

  • 9 games at 2B
  • 2 games at SS
  • 3 games in OF

He has a LOT of speed and even hit a home run too. He stole 20 bases in every season he played in the KBO, scored 79+ runs in all but one season and can play multiple positions as I’ve already mentioned. He’s a solid option.

 

Connor Norby, 2B/3B, Miami Marlins

ESPN: 6% / Yahoo: 11%

FAAB: 7-9%

Fresh off having a nine-game hitting streak snapped, Connor Norby has changed his approach at the plate and it’s yielding positive results. He has a .788 OPS over his last 10 games with four extra-base hits and two stolen bases, and those are two big-time factors into why Norby was fantasy viable coming into the year.

He’s in the 87th percentile for sprint speed and Fangraphs listed him with 50/50 speed and 45/50 power. Really solid tools for a player that’s nearly 90% available on both ESPN and Yahoo! You can slot him in at 2B, not just 3B, which is arguably the worst position in fantasy baseball.

 

Drake Baldwin, C, Atlanta Braves

ESPN: 4% / Yahoo: 7%

FAAB: 2-3%

He doesn’t qualify just yet, but Drake Baldwin’s numbers look incredibly interesting. 

You don’t see too many catchers this prolific on the offensive side of things and although Sean Murphy exists, it’s hard to keep Baldwin out of the lineup with how many bats in their lineup are struggling. Baldwin came into 2025 as a consensus top-65 prospect and Baseball Prospectus even had him listed as 37, so success isn’t all that surprising. He’s worth taking a shot on if you’ve gotten lackluster production at catcher this year.

 

 

 

Fantasy Baseball Waiver Wire Outfielders

Josh Lowe, OF, Tampa Bay Rays

ESPN: 12% / Yahoo: 61%

FAAB: 9-11%

There is a massive discrepancy between Yahoo! Fantasy and ESPN when it comes to Josh Lowe’s rostership, but he’s available in nearly 90% of ESPN leagues but less than 40% on Yahoo!, so this one’s for you ESPN players. Lowe is a player that has already flashed 20-homer, 30-stolen base upside back in 2023 and then in just 353 at-bats last year, he belted 10 bombs and had 25 stolen bases.

In his return game, he led off, hit a home run and had three hits, and that’s the type of player Lowe can be. We ALSO haven’t gotten to see Lowe play his home games in Tampa yet, which has played entirely into the offense's hands.

 

Austin Hays, OF, Cincinnati Reds

ESPN: 13% / Yahoo: 23%

FAAB: 3-5%

As everyone begins to hop off the Austin Hays bandwagon, we should be jumping right back on. He was actually dropped in a lot of Yahoo! Fantasy and ESPN leagues and that’s a mistake. He homered on Friday and a lot of his Statcast data suggests he’s still a plus hitter, he’s just not qualified due to his latest IL stint. 

That’s the good stuff for a guy playing his home games in Great American Ballpark and hitting in the middle of the Reds’ lineup.

 

Addison Barger, 3B/OF, Toronto Blue Jays

ESPN: 1% / Yahoo: 5%

FAAB: 1-2%

He doesn’t qualify because he’s only had 65 at-bats this year, but Addison Barger is hitting everything extremely hard this year. His average exit velocity is 94.7 MPH and his expected wOBA sits at .349, expected slug is .473%, and expected average is .282. He’s someone who can play at 3B and the OF, but given the lack of depth at OF on the waiver wire, Barger won’t cost you a lot and has been a legit major league hitter of late.
