Welcome to the Waiver Wire Picks, our daily fantasy baseball article that looks at the best players in baseball that you should be adding to your rosters. We’ll look at the players that are likely to be available in most leagues, as well as some deep league waiver wire options, and we’ll also look at the most added players in fantasy baseball across the major sites, and let you know which players to add, and which players you can leave on the wire.
Top Priority Player to Add
Joey Cantillo (CLE), LHP — 30% Rostership
Cantillo, 26, was one of my favorite back-end draft picks heading into 2026. I rostered him in four of my six leagues (including two dynasties), and he’s certainly repaid me with an excellent start to 2026. Through 14.2 innings, the southpaw has turned in a 2.45 ERA/1.85 FIP (seventh best in MLB), .208 BAA, and a monster 33% strikeout rate.
The walk rate is still a bit of a concern as it was last year, but there’s no denying the swing-and-miss stuff despite below-average velo. He’s another reason why there’s more to a scouting report than just “mph”. The 7.2 extension and ~18″ induced vertical break (iVB) on his four-seamer allows it to play up to such an elite level – .172 xBA, .286 xwOBA – despite sitting just 92 mph.
His secondaries have been uber-effective as well. The changeup has posted a whiff rate close to 50% on 21% usage as a platoon-neutral pitch, his slider and curveball have each generated whiff rates of 30%, and the curveball (.189 xwOBA) is primed to take another step forward with more usage against RHBs going forward.
Cantillo has limited pull air rate (12%) and mistakes (3%), is elite at limiting ideal contract rate (ICR) (22% – 95th percentile among SPs in 2026), and has an ideal plate appearance (IPA) 15% of the time — good for sitting in the 92nd percentile. If he’s available, now is the time to invest and watch his stock soar.
Yahoo and ESPN Most Added Players
Foster Griffin is a name to watch here. The 30-year-old has turned in a 2.70 ERA and 26% strikeout rate through 10 innings to start 2026, stranding a whopping 98% of baserunners. The southpaw features 6.5′ of extension paired with a seven-pitch mix, including a changeup, splitter, and curveball that have all registered whiff rates over 38% through a very limited sample size.
Quite a few intriguing names on ESPN’s most-added list.
Kyle Harrison (MIL) is the first arm that comes to mind. The 24-year-old is very fastball dependent, but has started to find some success with Milwaukee after the organization has taken Boston’s tweaks to the next level. He’s posted a 34% strikeout rate and 2.62 ERA through 10.1 innings to start 2026.
Parker Messick (CLE) is the second arm that I want to highlight. He’s allowed just one earned run – a solo homer – through 11 innings to start 2026. A command artist, Messick posted a sub-5% walk rate last year and owns a 20% K-BB rate in 2026 following an uptick in strikeout rate.
Jorge Soler (LAA) has been a revelation, mashing four home runs in 14 games. It’s best you add him in a category league, though, considering he has been striking out often (37%) chasing the longball. He’s a short-term add to bring in some pop before his magical powers wear off.
Jordan Walker (STL) has been a buzzy name lately, and it’s all thanks to a few minor tweaks. He’s always been a high EV guy, but hasn’t been able to pair that with the rest of the quality-of-contact metrics you’d like to see. In 2026, Walker has traded ~2% of his strikeout rate for walk rate, increased his hard-hit rate and barrel rate tremendously, and most notably, elevated the ball more, helping aid his xwOBA. People also seem to forget he’s only 23 years old. Walker is a big-time name to watch as the season unfolds.
Streaming Pitchers
Our guy Nick Pollack does a wonderful job at highlighting and ranking streaming pitcher options… check out his list here!
Noah Cameron (KC), LHP — 45% Rostership
Cameron boasting a sub-50% rostership rate is unacceptable heading into Week 4. He’s been elite through two starts, posting a 1.69 ERA/1.83 FIP with an elite 5% walk rate and 1.13 WHIP through 10.2 innings pitched. He was exceptional last season as well (2.99 ERA). What more does the young southpaw need to do to prove his worth?
Brayan Bello (BOS), RHP — 18% Rostership
Bello has had such an intriguing start to the season – while he owns a 9.00 ERA/5.65 FIP and subpar -0.1 fWAR, the young right-hander has seen his swing-and-miss explode off the charts. His CSW% is up 7%, swinging-strike rate is up over 10%, and currently sports an elite 73% zCon rate. Strikeouts are bound to come, and so is positive regression. I like Bello as a stash option and perhaps a start option against a below-average Cardinals offense.
Adrian Houser (SF), RHP — 4% Rostership
As Nick mentioned, Hauser could be an intriguing deep league add. The 33-year-old won’t blow you away with swing-and-miss, but he’ll pitch well enough to earn a win against an Orioles’ lineup that hasn’t found its groove to start the year.

Nasim Nuñez (WSH), INF — 4% Rostership
Nunez won’t do much damage offensively (although the underlying metrics indicate he could see some positive regression soon), but he will help boost production in one major category many fantasy managers could use heading into Week 4. The 25-year-old has already tallied a whopping seven stolen bases in 11 games — second-most in all of MLB. If you need to swipe some bags to win a category, Nunez is your guy.
