FAAB Frenzy and Waivers Wild: Week 4

Every Monday, this column will break down the most popular waiver wire and free agent acquisitions of the weekend.

Fantasy baseball managers know that our game is the ultimate test of grit, grind, tenacity, and patience. Unlike fantasy football, where league titles can be won with minimal in-season activity, fantasy baseball leagues require incessant attention and activity. Particularly when it comes to free agent adds and drops. Real-life baseball managers are constantly adjusting batting orders, players are frequently optioned to and promoted from the Minor Leagues, and injuries occur almost daily. There’s no resting on our laurels. We must always stay vigilant with league news and notes and remain active on the waiver wire if we want to win our leagues.

Every week, I’ll dig into the top adds on the ever-popular Fantrax and in the NFBC Online Championship (OC), a national mid-stakes contest with 240 total leagues of 12 and a six-figure grand prize. Reviewing player adds between the two should provide us with a well-rounded perspective and barometer of the fantasy baseball marketplace.

Week 3 Overview

Cardinals outfielder Jordan Walker smashed five dingers last week and now leads the Majors in home runs (seven).

Oneil Cruz and Jakob Marsee each stole three bases in Week 3 games. Cruz swiped six total bags last week and enters Week 4 tied with Drake Baldwin atop the FanGraphs 12-team Player Rater ($41.7).

James Wood earned 12 hits and walked six times (only 4 Ks) in 28 plate appearances. He slashed .545/.655/1.091 last week. The Nationals are scheduled to play seven games in each of the next two weeks.

A few hitters with rough weeks: Mark Vientos (0-17), Michael Busch (1-20), Munetaka Murakami (1-20, 9 Ks), Adolis García (1-20, 8 Ks), and Josh Naylor (1-19), whose batting average is down to .102 and has no extra-base hits.

Last week’s saves leaders (three apiece) were Lucas Erceg and popular waiver add, Jakob Junis. Last week’s popular add, Bryan Baker, earned two saves but served up three earned runs in three innings.

Starting pitchers Max Scherzer and Ryan Feltner gave up the most earned runs (10 each), though Scherzer pitched 4.1 innings and Feltner 9.1. Sandy Alcantara was roughed up by the Tigers (10 H, 7 ER in 6 IP) after three consecutive gems.

Of the 31 pitchers who drew two starts last week, five earned wins in both of their starts: Joe Ryan, Germán Márquez, Taj Bradley, Michael Wacha and José Soriano.

As we did last week, let’s review the top trending acquisitions for Fantrax (waivers) and the NFBC 12-team OC (blind bid FAAB), but let’s add in Yahoo’s top adds as well. Soriano is the early fantasy MVP and the top overall player on the Player Rater ($51.5).

Roster % is the current percentage of leagues rostering the player; +/-  is the percentage of leagues the player was added in the previous week

Jorge Soler was added in 25% of Fantrax leagues. His roster percentage is only up to 68%, which seems low. A healthy Soler is a great source of power, though he’ll certainly do his part to drain our batting averages.

% Added is the percentage of leagues that added the player; AWB stands for average winning bid

Braves pitcher Didier Fuentes was awesome in spring training (13 IP, 1 ER, 18:1 K:BB) and has 15 strikeouts with five walks and one run allowed in two Triple-A starts. He drew the highest average winning bid among SPs in NFBC OCs ($52) though is still available in 3% of leagues. With Reynaldo Lopez’s suspension shortened and him slated to start on Tuesday, the Braves won’t need another starter until the following week. Those who acquired Fuentes hope that he joins the rotation then.

Relievers

Jakob Junis was the top target among relievers this weekend. He popped onto our radars on Monday when he earned a save. He did it again on Tuesday and once more Sunday, just a few hours ahead of Sunday evening’s FAAB deadline. Robert Garcia and Chris Martin were supposed to be the ninth-inning co-committee, but they played themselves out of future opportunities, at least for now. Righty Cole Winn and lefty Jacob Latz (converted reliever) have moved up in the hierarchy as late-inning setup men. Winn locked down his first career save on Wednesday and a hold on Sunday. Winn hasn’t allowed a run in eight appearances and sports a 14.8% swinging-strike rate. He has better stuff than Junis, but Junis has superb control (6% career walk rate) and is a dependable veteran who appears to be extending job security in this new role. He spent the bulk of his career as a starter. Over the last two seasons, as a reliever with the Giants and Guardians, Junis owns a 2.83 ERA, 1.04 WHIP, 20.1% K and 4.9% BB.

Riley O’Brien (added in 17% of Fantrax leagues) has been stellar this season — 4 SV, 1 W, 1.41 ERA (2.05 xFIP), 8 K with no walks or earned runs allowed in eight appearances.

Joel Kuhnel is a new face in the fantasy sphere and is potentially in the mix for save chances with the Athletics. He closed out Sunday’s contest (1-0 over the Mets), his second save of the season. Mark Leiter Jr. (Tuesday, March 31) and Hogan Harris (Thursday, April 9) are the only other relievers to earn saves for the A’s so far. Kuhnel is 31 years old and a big guy (6’5”, 290) who has one full season in the Majors (6.36 ERA in 58 IP with the Reds in 2022), but has otherwise toiled in the Minors for different organizations. Kuhnel and Harris (the bullpen’s only lefty) will likely share save opps in the short term. Justin Sterner is their most consistent reliever since 2025 (his rookie season) and could get into the mix of save chances soon. Kuhnel has more fantasy value in 15-team leagues and can be ignored in 10/12-teamers for now, especially with the A’s playing at home all week.

Starting Pitchers

Jeffrey Springs is almost three years removed from his Tommy John surgery. A converted starter, Springs had a dominant 2022 season (2.46 ERA, 1.07 WHIP, 26%K, 5.6% BB in 135.1 IP) before his 2023 season ended abruptly. He joined the A’s in 2025 and managed a 4.11 ERA (4.60 SIERA) in 171 innings, though his strikeout rate dipped under 20% for the first time. His arsenal isn’t overpowering, but his changeup is top-notch and he has always exhibited above-average control. Springs has pitched well through three starts (1.47, 0.76) though it won’t be all sunshine and rainbows this season. Springs has been lucky (.170 BABIP, 3.91 xFIP, 3.97 SIERA) and negative regression will undoubtedly rear its ugly head — specifically, in the 100+ degree Sacramento weather this summer. Springs hasn’t allowed a home run yet this season (1.47 HR/9 last season). He is slated to make his second and third home starts of the season this week, against the Rangers and White Sox. Springs could be a mainstay on 12-team rosters and maintain a sub-4.00 ERA for the season.

Joey Cantillo’s breakout doesn’t seem to be appreciated by the Yahoo community (only 38% rostered). The crafty lefty with the occasional case of the location yips has 20 strikeouts and seven walks through his first three starts (14.2 IP). His cutter and changeup are plus offerings. I don’t foresee Cantillo having issues maintaining his rotation spot with the Guardians, but I can’t say the same about a sub-10% walk rate.

Giants starter Landen Roupp is off to a nice start, and perhaps even a bit unlucky (.304 BABIP, 3.24 ERA vs. 2.67 xFIP, 2.95 SIERA). It’s unlikely that Roupp will end the season with an ERA better than 3.50, but it’s certainly possible. Roupp often issued too many free passes in his starts last season, so it’s nice to see his walk rate down (from 9.5% to 7.2%), albeit just three starts. He will likely have his hands full in the next two weeks. He is expected to face the Reds in Great American Ball Park on Wednesday and is lined up in the following week to face the Dodgers, at home.

Javier Assad may be one-and-done after this start in Philadelphia if Matthew Boyd remains on track to return this weekend.

Hitters

Nasim Nuñez is all speed and nothing else. Make sure you only add him on squads where you don’t already have Chandler Simpson or José Caballero.

Angel Martínez had an incredible week — 13-42, 7 R, 1 HR, 6 RBI, 4 SB, .310/.383/.452. He mostly starts and bats first or second against left-handed pitchers, but earned a start against a righty on Friday. Not sure we can call him an everyday player yet, so let’s see if he earns some starts against righties this week. When we added Martínez over the weekend, the Guardians were slated to face up 4 LHPs. That has since changed with the Orioles optioning lefty starter Cade Povich in favor of ol’ gascan righty, Dean Kremer. The Guardians may only square off against two lefty starters now.

Diamondbacks rookie Jose Fernandez has started six straight games, at first base, third base, and designated hitter. He has earned playing time with somewhat steady production and because of injuries to Pavin Smith and Carlos Santana. By the way, Fernandez was seven years old when Santana made him Major League debut.

Drop of the Week

It may be time to move on from Astros interim closer Bryan Abreu. Abreu did not allow a run in his appearance on Sunday, the first time in seven tries. His velocity drop is worrisome, lefty Bryan King has been exceptional, and Josh Hader may be back before the end of the month.
