Here’s how the Mariners’ farm system performed Saturday:

2019: .290/.358/.492, 7-2B, 4-3B, 8 HR, 34 RBI, 20 BB, 49 SO

Long belongs in the big leagues right now. The end.

No. 11 Jake Fraley, OF
SAT: 2-5, 3B, 2 RBI

No. 26 Gerson Bautista, RHR
SAT: 1 IP, H, BB, 3 SO
2019: 11 IP, 7 H, 4 ER, 5 BB, 18 SO

Bautista reportedly touched 101 on the stadium gun in this outing. That’s velo.


NEW: Top 40 Prospect Rankings Update


No. 30 David McKay, RHR
SAT: DNP
2019: 23 G, 35.2 IP, 24 H, 27 BB, 56 SO, 4.05 ERA


No. 32 Tim Lopes, 2B
SAT: 1-4, BB, 2 SO
2019: .284/.349/.422, 22-2B, 3B, 5 HR, 37 RBI, 28 BB, 59 SO, 21 SB


Arkansas Travelers (AA) — Texas League

No. 3 Justin Dunn, RHS
SAT: DNP
2019: 70.1 IP, 65 H, 27 ER, 21 BB, 90 SO, 3.45 ERA


No. 5 Justus Sheffield, LHS
SAT: 8 IP, 2 H, ER, 2 BB, 8 SO
2019: 67 IP, 71 H, 44 ER, 43 BB, 64 SO, 5.91 ERA

Sheffield had a no-hitter through six and threw 64 of 96 pitches for strikes. He’s clearly found some rhythm in Arkansas.

The stuff is better as a result of better extension and finish and, of course, a consistent and repeated delovery with more lower-half energy.

The slider has benefitted the most, but Sheffield is getting real value from his fastball his last three starts. Might be time to check the fix in Triple-A again. Sheffield, if he keeps throwing strikes, is likely to see the majors rather quickly.

SCOUT: “He was a mess three weeks ago. He’s working with some pace now. He sure did tonight … had an average slider tonight but put it where he wanted to. Saw a few changeups.”


No. 7 Kyle Lewis, OF
SAT: 1-5, RBI
2019: .257/.355/.374, 14-2B, 2-3B, 4 HR, 40 RBI, 40 BB, 86 SO, 2 SB


No. 14 Evan White, 1B
SAT: 2-4, BB, SO
2019: .300/.362/.481, 7-2B, 2-3B, 9 HR, 27 RBI, 19 BB, 52 SO, SB


No. 20 Ricardo Sanchez, LHS
SAT: 5 IP, H, 0 R, BB, 6 SO
2019: 81 IP, 89 H, 37 ER, 22 BB, 79 SO, 4.11 ERA


No. 21 Dom Thompson-Williams, OF
SAT: 2-4, 2-2B, RBI, BB
2019: .252/.330/.447, 18-2B, 3-3B, 8 HR, 28 RBI, 26 BB, 73 SO, 13 SB

Thompson-Williams has turned things around after a bad May and start to June. He’s 16 for his last 36 (.444) with seven extra-base hits since June 18.

“He’s back to using the middle,” said one scout. “At least a few of his doubles the past week or so have been the other way.”


No. 27 Jake Haberer, RHR
SAT: DNP
2019: 23 G, 32 IP, 29 H, 19 BB, 45 SO, 5.91 ERA


No. 28 Joey Gerber, RHP
SAT: 1 IP, 0 H, 0 R, 0 BB, 2 SO
2019: 25 G, 26 IP, 17 H, 10 ER, 12 BB, 39 SO

Gerber’s first appearance in Double-A went very well.  He pounded the zone with fastballs, per usual.


No. 35 Wyatt Mills, RHR
SAT:
DNP
2019:
31.2 IP, 33 H, 16 ER, 12 BB, 33 SO, 3 SVS


No. 38 Luis Liberato, CF
SAT: 0-3, BB, 2 SO
2019: .272/.342/.410, 6-2B, 7 HR, 30 RBI, 21 BB, 51 SO, 4 SB

UR Art Warren, RHR

UR Darren McCaughan, RHS
SAT: DNP
2019: 14 GS, 2.73 ERA, 85.2 IP, 85 H, 7 BB, 71 SO


Modesto Nuts (A+) — California League (All-Star Break)

No. 1 Jarred Kelenic, OF
SAT: 0-4, RBI, SO
2019: .287/.365/.542, 17-2B, 4-3B, 13 HR, 37 RBI, 30 BB, 64 SO, 11 SB

Kelenic is indeed in a bit of a slump, but we’re never going to ‘worry’ or grow ‘concern’ so no need to ask. K? Thanks.


No. 2 Logan Gilbert, RHS
SAT: 3 IP, H, BB, 3 SO
2019: 71.2 IP, 53 H, 16 ER, 15 BB, 94 SO, 2.15 ERA

Gilbert, in what is believed to be a planned short-script, threw 25 of 41 pitches for strikes.

SCOUT: “I still think he’s a ‘3’ but in a good rotation where the ‘2’ is a real ‘2’ and the ‘1’ is an ace.”

JAC: What’s the ceiling here, then?

SCOUT: “Peak Anibal Sanchez? Carlos Carrasco? Aaron Nola?”


No. 12 Cal Raleigh, C
SAT: 2-3, 2B, BB, SO
2019: .250/.325/.469, 18-2B, 13 HR, 48 RBI, 27 BB, 62 SO

SAT: DNP
2019: 16 GS, 86.2 IP, 93 H, 38 ER, 10 BB, 115 SO


West Virginia Power (A) — South Atlantic League (All-Star Break)

No. 4 — Julio Rodriguez, OF

2019: .236/.297/.431, 5-2B, 11 HR, 12 BB, 71 SO


Everett SquaSox (SS-A) — Northwest League

No. 6 George Kirby, RHS
SAT: DNP
2019:


No. 15 Brandon Williamson, LHS
SAT: DNP
2019:


No. 18 Carter Bins, C
SAT: 0-1, 3 BB, SO
2019: 8-31, 2 HR, 10 BB, 12 SO.


No. 24 Austin Shenton, 3B
SAT: DNP
2019: 12-for-35, 2-2B, 2 BB, 8 SO

Shenton was removed after a diving play in the fourth inning Tuesday and hasn’t played since.


No. 25 Damon Casetta-Stubbs, RHS
SAT: DNP
2019: 60.1 IP, 76 H, 24 BB, 52 SO


No. 34 Tim Elliott, RHS
SAT: DNP
2019: 6 IP, 6 H, 2 ER, 2 BB, 8 SO


No. 37 Jorge Benitez, LHS
SAT: DNP
2019: 10 IP, 8 H, 3 ER, 7 BB, 6 SO


UR Kelvin Nunez, RHP
SAT: 3.2 IP, 3 H, 2 ER, 4 BB, 2 SO
2019: 15.1 IP, 16 H, 5 ER, 5 BB, 11 SO

The 19-year-old Nunez is very interesting. He’s about 6-foot-1 and 180 pounds, but the arm action is easy and there’s natural sink to the fastball. He could end up being a ground ball rotation candidate.


UR Robert Perez, 1B
SAT: 0-4
2019: .230/.300/.410, 4-2B, 3B, 4 HR, 12 RBI, 8 BB, 37 SO


UR Juan Then, RHP
SAT: DNP
2019: 9 IP, 7 H, 4 ER, 2 BB, 8 SO


Arizona Mariners (R) — Arizona Rookie League

No. 19 Juan Querecuto, SS
SAT: DNP
2019: 1-11, 3 BB, 5 SO


No. 23 Levi Stoudt, RHS
SAT: DNP
2019:


No. 13 Isaiah Campbell, RHS
SAT: DNP
2019:

In 18 starts for Arkansas, the right-hander went 12-1 with a 2.13 ERA. He rung up 125 strikeouts versus 22 walks in 118 1/3 innings of work.

I’d be surprised if he throws more than a few innings somewhere this summer — which was the plan for Logan Gilbert last summer before he became ill. It’s entirely plausible Campbell will not make his pro debut until next spring.


No. 29 Brayan Perez, LHS
SAT: DNP
2019: 15 IP, 13 H, 5 ER, 2 BB, 11 SO


No. 31 Ty Adcock, RHR
SAT: DNP

No. 33 Adam Macko, LHS

2019:


UR Tyler Driver, RHP
SAT: 4 IP, 2 H, ER, 0 BB, 4 SO
2019: 9 IP, 6 H, 3 ER, 2 BB, 9 SO

The Mariners’ 18th-round pick has pitched well in all three of his starts. Maybe he’ll see this sentence, DM me on Twitter and tell me more about his arsenal. 🙂


UR Nolan Perez, 3B
SAT: 2-5, 3B, HR, 4 RBI
2019: .278/.289/.528, 2B, 3B, HR

Perez is a switch-hitting third baseman with arm strength and quick hands in the batter’s box, projecting some power.


UR Danny Chang, LHP
SAT: DNP
2019: 8 IP, 6 H, 2 ER, BB, 15 SO


UR Blake Townsend, LHP
SAT: DNP
2019: 5.1 IP, 8 H, 4 ER, 0 BB, 8 SO


UR Luis Veloz, OF
SAT: 2-5, 2B, SO
2019: 4-17, 7 BB, 3 SO

There’s leverage to be had and enough bat speed to projected big-league power. He may have the best strike zone judgment in the Arizona League and at 6-foot-4 and 185 pounds there’s physical projection on which to dream.

“His swing is stiff and that may be restricting his (plate) coverage and robbing him of bat speed, but he’s got tools.”


UR Edwin Gil, 3B
SAT: 0-4, RBI, SO
2019: 17-68, 7-2B, 3B, 2 HR, 11 RBI, 2 BB, 23 SO


DSL Mariners (R)

No. 8 Noelvi Marte, SS
SAT: 1-4, BB, SO
2019: .317/.372/.500, 5-2B, 2-3B, 2 HR, 14 RBI, 9 BB, 22 SO, 9 SB

“Marte has a chance to be really special,” said one Latin America scout. “If he hits at all he’s a major leaguer.”


UR Ortwin Pieternella, C
SAT: 2-3, 2B, BB
2019: .341/.500/.561, 4-2B, 3B, HR, 8 RBI, 13 BB, 7 SO, 3 SB

I know very little about Pieternella, but he’s 20 years old, a catcher, and has one of the more intriguing 15-game stat lines in the DSL.

Not only does the slash look good (small sample, yes), but he has 13 walks against seven strikeouts, plus three stolen bases and a triple. My second question to Lat Am scouts will be: Can he run, too?

UPDATE: My second question was indeed that, but the answer to the first question was more crucial to Pieternella as a prospect. I discussed that and tons more on the Mariners’ lower-level talent in the latest edition of Baseball Things.
