FAAB Frenzy and Waivers Wild: Week 6

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 5 Overview

Ildemaro Vargas continues to tear it up, out of nowhere. He lead all hitters with 12 RBI last week with his team only playing five games, albeit two of them in Mexico City. More on him later. Nolan Arenado had an incredible week as well, going 11-18 with a homer and seven runs scored. That two-game Mexico City series did not disappoint as the Diamondbacks and Padres combined to score 29 runs.

Since returning from Paternity Leave, Michael Harris II is slashing .429/.468/.786 with 4 HR and 13 RBI in 13 games. Talk about #DadPower.

A few notable hitters who hit the skids in Week 5: Willy Adames (1-22), Dillon Dingler (1-21), Luis Robert Jr. (1-15), Austin Riley (2-26), CJ Abrams (2-22) and Kyle Schwarber (3-27). Oneil Cruz only managed three hits (3-23), but two were home runs. Over the last two weeks, Ezequiel Tovar is 5-43 (.116) with no RBI. Already one of the biggest chasers of bad pitches and arguably the worst plate discipline among MLB regulars, Tovar’s YTD walk rate (2.7%) and strikeout rate (30%) are worse than ever before. There will be better days ahead, but managers in 12- and 10-team leagues should continue finding alternatives for their rosters.

Nasim Nuñez was the only player with five stolen bases last week, and is the current Major League leader (13). Right behind him are José Ramírez, José Caballero (11) and Oneil Cruz and Jakob Marsee (10). Nuñez has the lowest ISO (.012) among 180 qualified hitters.

It was another week where two-start pitchers’ wins hovered around weekly expectations. Among 30 starting pitchers with two starts last week (let’s include Sean Burke and Chase Dollander, who entered their second appearances early in the games), only three earned wins in both — Justin Wrobleski, Landen Roupp, and Spencer Arrighetti — a rate of 9.6%. Nolan McLean led all pitchers in strikeouts (17 in 11.2 IP), Dollander was second (16 in 13) and Kyle Harrison was third. Harrison only pitched three innings on Tuesday (3 Ks) before punching out 12 Pirates in six innings on Saturday.

Louis Varland was the only reliever with three saves in Week 5. Rockies Victor Vodnik got rocked for five runs on Thursday, and secured a clean save in one of the doubleheader contests against the Mets on Sunday.

Let’s dive into the top trending acquisitions for Fantrax (waivers) and the NFBC 12-team OC (blind bid FAAB):

Ildemaro Vargas was the top addition on Fantrax. He’s been the Diamondbacks top producer, leading them in HR (six), RBI (20) and in wRC+ (203), wOBA (.473), and ISO (.354). His power metrics are all below average — 87.6 mph EV, 37% hard-hit, 7.1% barrel. That barrel rate is nearly three times his career rate, as is his seven degree launch angle. He recently earned first base eligibility, as he’s made himself comfortable there in the absence of Carlos Santana. With Geraldo Perdomo out of Sunday’s lineup, Vargas had the opportunity to lead off for the first time this season and delivered in grand style — 3-5, 3 R, 1 HR, 4 RBI. Vargas won’t finish the season as a top-three hitter in this offense, but could maintain an everyday (or almost everyday) role in this shallow lineup and deliver his best season. Though that shouldn’t be difficult considering he has never earned more than 303 plate appearances in a season.

The recent waiver pickup timing of Carlos Cortes is symbolic of the essence of fantasy baseball chaos. Cortes was a somewhat popular add before Week 4. The Athletics had seven home games, Brent Rooker was on the IL, and Cortes’ playing time was increasing, so the opportunity for production was ripe. Cortes went 3-16 with one run and one run batted in that week. Most managers dropped him before his epic Week 5 run of .542 (13-24), 4 R, 3 HR, 7 RBI. Now he’s popular again, but Rooker is back and Cortes will likely only make two starts, since the A’s are expected to face four lefty starters and Cortes doesn’t typically start against them. If you picked him up in weekly leagues, make sure you bench him for the week.

Nathan Church has been a pleasant surprise for the Cardinals. The left-handed-hitting 25-year-old rookie was an 11th-round draft pick in 2022 and produced between Double-A and Triple-A last season: .329/.386/.524, 13 HR, 16 SB in 385 PA (86 games). Church has been a mainstay against right-handed starters,, and has covered all three outfield positions, though he mainly plays left field. He stepped into the fantasy scene last week, going 8-19 with 4 HR, 7 RBI and a stolen base in six games, as the Cardinals faced all righties. He sports an 11.5% barrel rate, though his average exit velocity (86.6 mph) and hard-hit rate (38.5%) remain subpar. The Cardinals play seven this week and five of those matchups are against RHPs, though Church will be tested going up against the likes of Paul Skenes, Braxton Ashcraft, and Emmet Sheehan. His power/speed combo is intriguing for deeper leagues and he should not yet be on the radar for 12-teamers or shallower formats. Though, if matchups line up as they currently project, Church and the Cardinals should face seven RHPs the following week (Week 7, May 4 – May 10), though more tough tests are to come against studly Brewers and Padres arms.

AWB stands for Average Winning Bid

This was a huge weekend for spending in NFBC managers, on par with last weekend when Noah Schultz and Spencer Arrighetti both earned triple-digit AWBs. The big ticket was Red Sox southpaw Payton Tolle, who dazzled in his 2026 debut, punching out 11 hitters in six innings from the Yankees on Thursday. The hulking (6’5”, 250) and famously mustachioed 23-year-old rocks a killer 97-mph four-seam fastball, and mixes in a cutter, curve and sinker, with an occasional changeup. He is locked in to face the Blue Jays in Toronto on Tuesday, and has a good opportunity to remain with the big-league club even when Sonny Gray is activated. To keep Brayan Bello (9.00 ERA, 2.27 WHIP, 13% K, 11.3% BB in 22 IP) over Tolle in the rotation would be a travesty, but could be par for the course for a front office that just fired manager Alex Cora and is feeling the heat from their fanbase.

JR Ritchie had a strong career debut last Thursday. The Braves top pitching prospect boasting a 0.99 ERA over five Triple-A starts fired seven innings against the Nationals. Ritchie struck out seven, and gave up two walks and two runs on five hits (two home runs). The next day, Atlanta manager Walt Weiss confirmed that Ritchie would remain in the majors for now. His next start is confirmed for Wednesday, at home against the Tigers. The timing of Ritchie’s promotion and impressive debut was perfect. It was one of several factors that drove his fantasy free agent market price up over the weekend. Didier Fuentes struggled in his start the day before (and was subsequently optioned to Triple-A). Reynaldo López got shelled last Monday (4 ER in 1 IP), and on Sunday, it was announced that he would move to the bullpen to work on his mechanics. So, even with Spencer Strider’s upcoming activation off the IL, there is still an open rotation spot and clear opportunity for Ritchie to gain some momentum and lock himself into the rotation. I did not acquire Ritchie in any leagues this weekend, but would call myself a founding member of his fan club. I drafted him in my first 50-round NFBC Draft Champions back in November. I also drafted him in my live Main Event in Las Vegas and stashed him on my bench for the last 5.5 weeks. Who wants to pay retail anyway?

Jack Perkins is emerging as the Athletics most reliable bullpen option. After earning a save earlier in the week, Perkins impressed on Sunday by locking down a two-inning save. Middling veteran righty Joel Kuhnel ran into some trouble in two early-week appearances (6 H, 2 ER in 1.2 IP). In Sunday’s tilt against the Rangers, Kuhnel appeared in the fourth inning for banged-up starter J.T. Ginn. RosterResource currently displays Perkins, Kuhnel and lefty Hogan Harris as a committee. Though, Perkins is best suited to handle ninth inning duties, he’s an effective multi-inning arm who manager Mark Kotsay could easily deploy in various relief scenarios, including early innings. Perkins was my most-added RP, so I am ready to be hurt again. But I will not overreact to his usage this week and intent to stand firm with Perkins on my roster. Well, barring an 8-ER implosion or IL stint, of course.

Drop of the Week

This week, it’s a four-way tie between “closers” Edwin Díaz (LAD), Jordan Romano (LAA), Clayton Beeter (WSN), and Caleb Thielbar (CHC). Each stung in its own way — Díaz due to expectations and high-draft capital and Romano because of the ratio damage. Don’t be surprised to see more carnage next weekend in what is the craziest season for closers and saves in recent memory.
