Fake Baseball's Week 6 Weekly Waiver Wire & Pitcher Streaming Options (Fantasy Baseball 2025)

The best waiver wire options for week six of the fantasy baseball season

Over the years, these fantasy baseball waiver wire articles have become my favorite weekly content to put out. I find a lot of joy in putting my research into words and seeing it impact your rosters in a positive way. Not everyone has the time to spend hours scouring the waiver wire, checking for the guys nobody else is paying attention to. That’s where Fake Baseball comes in handy.

Last week’s list was full of prospects. I don’t plan on it going the same way this week. There are a lot of veteran guys playing at a high level that fall into the top of my waiver wire list for the week. The new guys are always flashy and fun with unlimited upside, it seems like, but that’s not always what you should be focusing on. A lot of times, it’s the boring, uninspiring names that can bring you the most value. Not very exciting, I know, but you know what is? Winning. And that’s what we’re here to do.

Before I get into this week’s list of names, I wanted to remind you guys that paid subscribers of Fake Baseball get two day early access to all articles. That includes the weekly waiver wire, Aaron’s Piquing Prospects series, and the other research-based articles I put out throughout the week. One hell of a deal for only $5/month ($50/year) if you ask me!

Catcher

Agustin Ramirez - Miami Marlins

ESPN: 8% | Yahoo: 29% | CBS: 38% | Fantrax: 56%

Remember the days when JT Realmuto was running wild on the basepaths and it blew our minds? Picture that, but in a worse lineup. What I’m trying to say is Agustin Ramirez has the ability to produce like 2022 Realmuto. The season he went 22/21. Agustin stole 22 bases in the minors last season while hitting 25 bombs and flashing excellent contact and power numbers. His plate discipline is top tier as well. There’s a lot to like about Agustin, and while I do have my worries about just how high his batting average can be, his OBP and XBH numbers will quickly help you forget about that. He has top-12 at the position upside right now.

Coming back to this real quick to say he just homered against my Mariners as I was working on finishing up the article. He’s a must add everywhere people. Don’t wait.

Edgar Quero - Chicago White Sox

ESPN: 1% | Yahoo: 2% | CBS: 15% | Fantrax: 37%

Quero is now officially a repeat offender on this list. He was my number one catcher to add last week, and he did not disappoint. I kinda wish he’d gone yard once just for fun, but four RBI in his first eight games to go along with two doubles and a .429 OBP. And don’t even get me started on the fact he’s only struck out twice. The only thing working against Quero is that horrible lineup in Chicago. Outside of that, there’s a ton to like about hi,m and he’s worth adding now if you were at all hesitant before.

First Base

Eric Wagaman - Miami Marlins

ESPN: 6% | Yahoo: 7% | CBS: 12% | Fantrax: 37%

I feel like every one of these articles I do, I come right out of the gate with multiple guys from the same team. I’m keeping the streak alive once again this week. Wagaman has come out of seemingly nowhere to be a fairly dependable option at first base thus far. He had a fairly successful MLB debut in 2024 with seven XBH in 18 games. Now in his first 38 total MLB games, he has 15 XBH, a strikeout rate below 20%, and a 24% line drive rate which screams continued success. He also makes elite in-zone contact (91% in 2025) and has no competition for at-bats right now. He has sneaky XBH and R/RBI upside this season and is way too available.

Rhys Hoskins - Milwaukee Brewers

ESPN: 11% | Yahoo: 35% | CBS: 58% | Fantrax: 76%

A little highly rostered for my taste, but still deserves to be here. Hoskins has taken on the role of home run merchant the last few seasons, and has now taken that a step further in 2025. His pulled airball rate has jumped to an insane 34.5%, his strikeout rate has dipped below 20%, he’s got a chase rate in the 91st percentile (wtf?!), and his 43.6% sweet spot rate is incredible. The fact that he only has three home runs is mind-boggling. He’s well on his way to 30+ home runs with numbers like this and should be owned in all leagues right now.

Second Base

Tim Tawa - Arizona Diamondbacks

ESPN: 1% | Yahoo: 2% | CBS: 6% | Fantrax: 23%

Time keeps ticking by, and Tawa just keeps on producing. He surprisingly got the call over Jordan Lawlar when Ketel Marte went down, and all he’s done since then is hit dingers and get on base. His four home runs are tied for the fifth most by a second baseman this season, along with the likes of Ozzie Albies and Jordan Westburg. His .378 OBP is fifth-best amongst second basemen with at least 40 plate appearances. Yet somehow he’s owned under 7% everywhere but Fantrax, where everybody and their momma is on someone’s roster. He’s very much a short-term producer with a long-term question mark, but Marte still has a while until he’s back, and Tawa is showing no signs of slowing down.

Gavin Lux - Cincinnati Reds

ESPN: 12% | Yahoo: 25% | CBS: 37% | Fantrax: 70%

Nobody with multi-position eligibility that’s starting essentially every day for a team playing their home games in Great American Ballpark should be this widely available in fantasy baseball leagues. Lux is eligible at both second base and outfield, two of the most premier positions in fantasy baseball. He’s also been productive as hell. He’s hitting .316 with an .837 OPS, which is what’s fueling his value right now. He has also either scored or driven in a run in seven of his last eight games. He’s spent almost every at-bat this season hitting fourth or fifth in that Reds lineup and is worth an add in deeper 12-team or larger leagues, or in leagues where you need a boost to everything but home runs and stolen bases.

Third Base

Josh Smith - Texas Rangers

ESPN: 8% | Yahoo: 21% | CBS: 52% | Fantrax: 62%

The super utility stud from Texas has now found himself with a prominent spot on many people’s waiver wire list. I’m not usually keen on giving you guys names that I know everyone else will, but this one feels warranted. Smith has found his way into an almost everyday role in that Rangers lineup and has shown he can produce in multiple ways. Six XBH, 11 runs scored, and three stolen bases are crucial in rotisserie and category leagues. He’s also cemented himself as a solid points league option too with the solid total bases number, .429 OBP, and 22% strikeout rate. He’s not going to be great at anything, but he’s good at a lot of things. In the fantasy baseball world, that’s exactly what you’re looking for on the waiver wire.

Ben Williamson - Seattle Mariners

ESPN: 1% | Yahoo: 1% | CBS: 4% | Fantrax: 12%

For a player who was touted as an elite defensive prospect with a below-average bat, Williamson sure has found a way to be productive at the plate. Now, keep in mind he has very minimal home run power. He had hit just four home runs in 150 minor league games prior to his promotion. But what he’s done since being called up gives hope for utility in other categories. He’s got a .785 OPS and an xwOBA of .368, which points to the hope for continued success. The Mariners’ lineup continues to surprise with their ability to score runs, and because of that, Williamson has already scored eight times in nine games. He’ll help you in both runs scored and batting average, with the ability to drive in some runs when there are actually people on base ahead of him. His fantasy baseball relevance may come with a time limit, so if you need a third baseman, now is the time to capitalize on his hot streak and be pleasantly surprised if it continues long term.

Shortstop

Brooks Baldwin - Chicago White Sox

ESPN: 1% | Yahoo: 1% | CBS: 6% | Fantrax: 17%

I wrote about Baldwin a few weeks ago, and, to be honest, not a whole lot has changed. I don’t love him in most leagues, but in deep leagues or leagues where you need some decent production for a short period, Baldwin can be your guy. Decent speed, a little light on power, but good enough zone contact and barrel rates to keep things interesting. Again, don’t expect a ton from Baldwin, but he can give you enough to at least tread water until a better option becomes available.

This is where I’d put another shortstop if there was one I was confident enough in this week, but I’m not, so I’m just going to let you know that Josh Smith would be my number one recommendation for shortstop as well

Outfield

Jordan Beck - Colorado Rockies

ESPN: 1% | Yahoo: 1% | CBS: 8% | Fantrax: 28%

The Rockies outfield (and lineup in general, for that matter) is full of guys who fall into the “Man, he can be so good if he figures it all out” category, and none of them have really separated themselves from the pack. Until Thursday. And Friday. That’s a long-winded way to say Jordan Beck just put together a two-game stretch for the ages. In technically three games, Beck has now hit five home runs, stolen a base, and raised his batting average 115 points. Beck’s power was never in question. Neither was his speed. It was his bat-to-ball skills we all worried about. He’s proven so far to be a bit streaky, but if this is what it looks like when he goes on his hot streaks, I don’t want anyone else in my leagues but me to be rostering him when it happens. Get this man on your team if you can.

Trevor Larnach - Minnesota Twins

ESPN: 2% | Yahoo: 3% | CBS: 18% | Fantrax: 37%

Larnach has always been a streaky hitter who really just needed an everyday role to carve out some success for himself. He’s getting that now, and honestly, he’s been great. Especially as of late. Four home runs in his last seven games to go along with nine RBI and six runs scored. He’s been hitting in the heart of the order since day one of the season and will definitely continue to as long as he’s hitting like this. It seems more like he’s at the beginning of a hot streak rather than the end, so he’s a safe bet to continue to hit dingers every chance he gets.

Starting Pitcher Streaming Options

Reese Olson - Detroit Tigers

Olson just spun himself an absolute gem against the Padres. An objectively good offense thus far. Now he finds himself set to face off twice next week against the Houston Astros and Angels. It’s an interesting combination of teams to face because both struggle mightily against right-handers. The Angels are hitting just .219 with a 25.8% strikeout rate, second worst in baseball. All of that while having the most home runs against right-handed pitching. The Astros, on the other hand, just flat out haven’t been good against right-handers. Their .239 batting average doesn’t strike fear into many pitchers’ hearts, and their .350 SLG is fifth worst in the league against righties. Olson needs to build on the confidence and success from his last start. Should he be able to do that, he should be in for one of the better two-start weeks in baseball.
