Seattle Mariners
2024 Fantasy Outlook
Munoz broke out in 2022 and carried that momentum into last season by recording Seattle's first save of 2023. Unfortunately, any hopes of him taking on more expansive closing duties were put on hold, as the right-hander suffered a shoulder sprain after just a few appearances. Munoz missed two months of action and was limited to setup duties upon his return with Paul Sewald locking down the 9th inning. When Sewald was traded, Munoz finally got some run as the M's closer. He recorded 11 of Seattle's 18 saves after the trade and finished the year with a career-high 13 overall. His strikeout and walk rates regressed a bit, but he maintained a 99th percentile whiff percentage (39.4%) and his groundball rate (59%) spiked since he implemented a sinker (19% pitch usage). Munoz enters 2024 as the favorite for closing duties in Seattle, but don't expect 70+ percent team save share. Munoz's health, plus the emergence of Matt Brash and Justin Topa, make a 50-60% share more realistic. Read Past Outlooks

Munoz got the last out of the ninth inning, and the Mariners rallied for a walk-off victory. He hadn't earned a save or a result in two weeks, allowing one run across four innings over his last four appearances. Munoz has a 2.81 ERA, 1.25 WHIP and 65:21 K:BB through 48 innings this year while adding 13 saves and 14 holds in 51 appearances.

2019
After signing a team-friendly, 4-year extension before the season, Munoz finally broke out in 2022, overcoming his biggest obstacle (health) to pitch a career-high 65 remarkable innings. The 24-year-old averaged 100.3 mph on his fastball and was in the 99th percentile or better in seven Statcast pitching metrics, including K%, whiff% and xERA/xWOBA. His 32.7% K-BB% was second-best among qualified relievers, while his 38.7% strikeout rate was fourth-best thanks to a slider that was among the best pitches in the league. Munoz limited baserunners (0.89 WHIP) to scale his way up Seattle's high leverage ladder, posting 22 holds while also getting a taste of closing with four saves. The Mariners have no financial reason to limit Munoz's save chances moving forward, so he could emerge as their primary closer in 2023. However, he must improve the effectiveness of his fastball (.338 BA, .500 SLG) and prove he's healthy after offseason foot surgery to take the next step.
Munoz, who missed the majority of the past two seasons after underdoing Tommy John surgery in March of 2020, walked two and struck out a batter over two-thirds of an inning during his lone appearance with the Mariners last year. The fact he was able to return was a surprise after he endured a setback in his recovery last March, but he was back on the mound in July and made substantial progress to return in October. The flamethrower didn't lose his velocity, as he topped 100-mph on his fastball during the outing, though his slider (82.2-mph) lost a few ticks on the radar gun and missed the plate on four of five pitches thrown. Munoz should be healthy entering 2022 and has upside worthy of a late-round flier for those speculating on saves. Just remember Seattle uses a closer committee and he may not get a ton of chances. Munoz is a riskier pick in draft-and-hold formats due to his limited innings potential.
Despite being shut down early in 2019 and slow played in the spring, Munoz experienced arm soreness, requiring Tommy John surgery in late March. The Padres dealt him to Seattle at the trade deadline. If there's a silver lining, it's the procedure was done early enough so Munoz should only miss a month or two this season. It remains to be seen if his 100-mph fastball loses any zip and if he's still willing and able to throw his sharp 86.5-mph slider 32% of the time. Munoz was on track to be a late-inning reliever with San Diego, and Seattle no doubt envisions him in a similar role. The Mariners are still rebuilding, so there's no reason to rush their 22-year-old prized arm back. Certainly in long-term leagues, Munoz is an intriguing stash. Don't assume it pays off in 2021 as a lot has to go right for him to collect second-half saves.
Munoz is blessed with a special arm. He averages 100 mph on his fastball -- yes, averages -- and his slider is a legitimate wipeout pitch. Munoz struck batters out at a 30.9% clip in his first foray into the majors while holding batters to a .186 average, and he allowed just one hit off his slider all season. Hitters chased his slider out of the strike zone more than half the time he threw it there (51.1 O-Swing%). When a pitcher sits at 100 with the fastball, the batter simply has to cheat to have any chance to hit it and that leaves them highly susceptible to the breaking ball. Munoz battled some walk issues after getting the call up after the break, but he had an above-average zone percentage which portends better control numbers. Still just 21, Munoz could use a bit more refinement, but this is a future closer profile if there ever was one. Expect him to open as one of the Padres' top setup men.
Munoz, the best relief-pitching prospect in baseball, can touch 103 mph with his fastball and may reach the big leagues this year as a 20-year-old. A dominant showing as the youngest player in the Arizona Fall League in 2017 served as his coming out party. Regularly touching triple digits as an 18-year-old can have consequences, and he was held back in extended spring training at the outset of 2018 with a tender elbow. After a PRP injection, Munoz was ready to make his season debut with short-season Tri-City in mid-June. He struck out nine in 5.2 hitless innings, leading to him getting promoted over Low-A and High-A to the Texas League, where he was the league's youngest player. His lower half is strong, but he is still adding good weight to his upper body. His mid-80s slider needs refinement, but he already commands an 80-grade fastball, so his secondary offering just needs to be OK for him to develop into one of the best closers in baseball.
