The Arizona Fall League is in full swing down here in Phoenix, but today we’re not here to discuss top prospects or future Mariners; rather, I’m interested in which coaches teams have opted to send in order to burnish their resumes and gain them experience with a diverse array of players from all different organizations. The Mariners are represented by long-tenured Mariner Jordan Cowan, acting as the hitting coach for the Javelinas, and pitching coach Dylan Gargas; look for stories on them later in the week.
Several big-league managers have experience helming an AFL crew: Kevin Cash, AJ Hinch, Torey Lovullo, Derek Shelton, and Warren Schaeffer have all managed AFL teams in the past. Generally there’s a bit of experience-building in between the two – Schaeffer managed the Salt River Rafters in 2022 before becoming interim manager of the Rockies in 2025 – but at the very least here are some names to put on your radar as the Mariners reassert their desire to look out of the organization for new voices on their coaching staff. (As such, I have left off Surprise’s manager, one-time Mariner and Sporcle remember-some-guys stumper Daniel Robertson.)
Billy Facteau (Bench coach, Peoria Javelinas)

Age: a literal infant
Current role: Development coach, Norfolk Tides (Orioles’ Triple-A team)
Relevant experience: 5+ years as development coach for the Orioles, played college baseball at Lynn University
Okay. OkAY. OKAY. I just need everyone to chill out and be cool for a moment and ignore the fact that Billy here looks like he came out of the beta version of the Orioles’ quirked-up-white-boy factory. And that his age starts with a 2. Remember we are scouting for the future here in addition to the current vacancies. And also, if you want a coach like this, someone who has been homegrown and nurtured in another organization, you’re going to have to dangle either more money or a bigger role (or both, ideally both) in front of them. It’d be too much to jump Facteau directly into a manager role – although he also has experience as a tech coordinator as an intern with the Orioles – but if the Mariners want to promote internally, I’d like to see an infusion of fresh perspective from outside the organization. As a former tech intern for the Orioles, he’s not only well-versed in tech like BlastMotion and Rapsodo but also how to translate that data to the players – including those who don’t speak English as a first language – and he has a special interest in coaching the outfield, a position in the Mariners system that’s maybe less robust than some other areas. A name to put on your radar.
Jeff Livesey (Hitting Coach, Surprise Saguaros)

Age: 60
Current role: Hitting coach, Reading Fightin’ Phils (Phillies’ AA team)
Relevant experience: Played professionally; 5+ years as MiLB hitting coach (WAS, PIT); two years as bench coach in NPB; one year as Marlins assistant hitting coach.
And now to the total opposite end of the spectrum. Livesey has the experience, but maybe not the fresh eyes the Mariners need. If you were a Kevin Seitzer fan, Livesey seems to have the same plainspoken approach to hitting, and the experience to back it up. Reading finished at the top of their division in the second half this season with the most runs scored in the Northeast division of the Eastern League.
Relevant quote:
(From his time with the Marlins):
“Sometimes with young hitters you get pitched tough, and guys get in-between pitches, and get kind of careful, We want to get to the point, we hunt our pitches. Good hitters hunt what they want to hit. When they get it, they take aggressive swings. That’s what we want to work towards. If they make two good pitches on us, we still have got something we can go to with two strikes. We can battle, and still be tough outs.”
Toby Nagel (Pitching Coach, Glendale Desert Dogs)

Age: ?
Current role: Pitching coach for the Blue Wahoos (Miami’s AA team)
Relevant experience: Driveline, Inspiration Academy
As you’d expect from someone who worked at Driveline, Nagel is a data-driven coach, but also adept at explaining that tech to players – you can see a ton of short videos he’s made explaining pitching tech and how to use it on TikTok. The Mariners are pretty rich in pitching coaches already but I wanted to throw Nagel onto this list just to get his name out there; his thoughts on command specifically make him a particular organizational fit (and make me dream about having him work with George Kirby).

Rafael Neda (Manager, Scottsdale Scorpions)

Age: 38
Current role: Manager, ACL Brewers
Relevant experience: 5+ years of playing professionally, 5+ years of managing the ACL Brewers
Bonus points: bilingual (born in Mexico, played at UNM)
The ACL Brewers have been to the playoffs twice under Neda, winning the ACL championship in 2023. Neda is another one who is deeply engrained with the organization he played for professionally, but hasn’t progressed past the complex level yet – maybe because he’s young enough that searching his name still provides stories about his playing days. As a player, Neda was a super utility player who played all across the diamond – including catcher, so a true super-super utility player. As a collegiate at UNM he was named to the Johnny Bench Award watchlist, with his coach calling him the best catcher in the country for his work on and off the field.
Ted Tom (Manager, Salt River Rafters)

Age: ? Older than Billy Facteau, for sure.
Current role: manager of the Wilmington Blue Rocks (Nationals High-A)
Relevant experience: 20+ years of coaching at the college level
Another one for those of you who value extensive experience, although Tom’s mostly comes at the college level. He has experience working with future big-leaguers at that level, though, such as Alex Freeland, now playing for the Dodgers; he also has a Mariners tie-in, having coached Dylan Moore during his time at UCF. At UCF, Tom mentored six all-conference selections, and after being promoted to hitting coach in 2019, helped the team reach the NCAA tournament.

There are lots because this man loves a podcast interview, which I love. I really enjoyed his thoughts on failure here and also “You need to fall in love with the monotony of every day” from this unfortunately very business-brained podcast.
Danny Worth (Manager, Peoria Javelinas)

Age: 41
Current role: infield coordinator with the Padres
Relevant experience: 8+ years of pro baseball plus a stint in the KBO; coached at Pepperdine before moving to MLB.
Worth is in his first year of MLB coaching, so he’s in the shallower end as far as MLB experience, but he has some of the most playing experience out of anyone on this list. He’s also got some college-to-big-league pipeline experience; he worked with current Tigers prospect John Peck at Pepperdine, helping him with his swing mechanics in addition to his infielding. At Pepperdine, Worth also mentored the 2018 WCC Player of the Year, Jordan Qsar, as well as five MLB Draft picks from the positions he coached.
