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

Tacoma Rainiers (AAA)– Pacific Coast League

No. 10 Jake Fraley, OF (24)
WED: DNP
2019: .295/.364/.532, 25-2B, 5-3B, 17 HR, 76 RBI, 34 BB, 87 SO, 22 SB

More on Fraley here.


No. 14 Shed Long, 2B/3B/OF (23)
WED: DNP (IL)
2019: .279/.343/.466, 7-2B, 4-3B, 8 HR, 35 RBI, 20 BB, 59 SO


No. 24 Taylor Guilbeau, LHP
WED: DNP
2019: 39 G, 48.2 IP, 40 H, 15 ER, 17 BB, 55 SO

8.2.2019: I was at Guilbeau’s Mariners org debut in Tacoma Friday night and he looked solid, sitting the high end of his velocity range for what I’m told is the third time in a row, dating back to his time in the Nationals organization.

He touched 97 mph with a little armside run, throwing just two fastballs under 95. He complimented the four-seamer with a firm, but above-average changeup — not the slider, although he mixed in a few of those, too — at 87 that induced a couple of whiffs.

Guilbeau has good arm speed and commanded the fastball fairly well in this outing.


No. 37 Tim Lopes, 2B (24) (MLB)
WED: (MLB)
2019: .301/.361/.474, 30-2B, 2-3B, 10 HR, 60 RBI, 36 BB, 70 SO, 26 SB


Arkansas Travelers (AA) — Texas League

No. 1 Jarred Kelenic, OF (20)
WED: 0-4, 3 SO
2019: .295/.368/.527, 28-2B, 4-3B, 17 HR, 52 RBI, 42 BB, 101 SO, 18 SB

No. 2 Logan Gilbert, RHS (22)
WED: DNP
2019: 118.2 IP, 84 H, 29 ER, 27 BB, 146 SO

No. 4 Justin Dunn, RHS (23)
WED: DNP
2019: 110.2 IP, 105 H, 45 ER, 33 BB, 132 SO

Dunn painted the outside corner at 94 a lot in this start and the slider was above-average most of the night, showing good depth and late break off better tilt than when Dunn doesn’t have a great feel for the pitch. He needed just 76 pitches (46 strikes) to get through five.


No. 5 Justus Sheffield, LHS (23)
WED: DNP
2019: 127 IP, 116 H, 57 BB, 127 SO

8.11.2019: Sheffield has been good in Arkansas, making 11 starts and covering 72 innings — 16 more than he managed in 13 outings for Triple-A Tacoma — while walking just 14 batters. He’s whiffed 79 and, most importantly, found his release point on the fastball.


No. 7 Cal Raleigh, C (22)
WED: 0-4, SO
2019: .251/.330/.485, 22-2B, 24 HR, 74 RBI, 45 BB, 101 SO


No. 8 Kyle Lewis, OF (24)
WED: DNP
2019: .269/.351/.411, 23-2B, 2-3B, 10 HR, 55 RBI, 51 BB, 126 SO, 3 SB

No. 12 Evan White, 1B (23)
WED: 0-3, BB, SO
2019: .287/.337/.489, 12-2B, 2-3B, 16 HR, 50 RBI, 22 BB, 78 SO, SB


No. 20 Ricardo Sanchez, LHS (22)
WED: 5.1 IP, 6 H, ER, 2 BB, 8 SO
2019: 133 IP, 138 H, 55 ER, 32 BB, 127 SO


No. 21 Aaron Fletcher, LHP
WED: DNP
2019: 35 G, 64.2 IP, 39 H, 12 ER, 15 BB, 76 SO


No. 23 Ljay Newsome, RHS (22)
WED: DNP
2019: 24 GS, 134 IP, 134 H, 51 ER, 13 BB, 150 SO

Vintage 2019 Newsome. He needed 75 pitches to toss six shutout innings and threw 53 of them for strikes.


No. 25 Dom Thompson-Williams, OF (24)
WED: 1-4, SO
2019: .235/.306/.407, 23-2B, 3-3B, 12 HR, 39 RBI, 34 BB, 130 SO, 14 SB

DT-W has had trouble with the swing-and-miss the past two and a half months, and isn’t getting to his power much, either.


No. 27 Jake Haberer, RHR (24)
WED: 0.1 IP, 0 H, 2 ER, 4 BB, SO
2019: 36 G, 47.1IP, 36 H, 30 BB, 66 SO


No. 31 Joey Gerber, RHP (22)
WED: 1.2 IP, 0 H, 0 R, 0 BB, 3 SO
2019: 38 G, 42.1 IP, 30 H, 17 ER, 20 BB, 61 SO


No. 33 Sam Delaplane, RHR (24)
WED: 1.2 IP, 0 H, 0 R, 0 BB, 3 SO
2019: 40 G, 60.1 IP, 34 H, 21 BB, 105 SO


No. 36 Wyatt Mills, RHR (24)
WED:
DNP
2019:
46.2 IP, 37 H, 20 ER, 16 BB, 56 SO

Mills continues to pitch well, limiting baserunners and missing bats with both fastball and slider.


Modesto Nuts (A+) — California League

No. 17 Braden Bishop, CF (25)
WED: (rehab) 0-4, 2 SO
2019: .286/.370/.488, 13-2B, 7 HR, 29 RBI, 21 BB, 38 SO, 2 SB


No. 29 Raymond Kerr, LHP (24)
WED: DNP
2019: 29 G, 81 IP, 75 H, 43 BB, 76 SO

West Virginia Power (A) — South Atlantic League

No. 3 Julio Rodriguez, OF (18)
WED: 0-3, BB, SO
2019: .293/.359/.490, 20-2B, 3B, 10 HR, 49 RBI, 20 BB, 66 SO


No. 15 Austin Shenton, 3B (21)
WED: 3-4, SO
2019: .311/.391/.522, 16-2B, 2-3B, 6 HR, 35 RBI, 19 BB, 39 SO


No. 40 Josias De Los Santos, RHP (19)
WED: DNP
2019: 17 G, 12 GS, 80.2 IP, 83 H, 28 BB, 62 SO

More on De Los Santos here.


Everett SquaSox (SS-A) — Northwest League

No. 6 George Kirby, RHS (21)
WED: DNP
2019: 5 G, 14 IP, 11 H, ER, 0 BB, 16 SO

8.10.2019: Kirby put up his best outing as a pro Saturday, throwing 32 of 45 pitches for strikes and inducing seven swing-and-miss results in the first 36.

He sat 92-93 mph and had “about 8 or 10” fastballs register in the 94-96 mph range, per one AL scout.

In the featured image at the top of the page, you can see Kirby’s spike curveball grip nicely.

7.23.2019: I caught Kirby’s third start in Vancouver and while his command wasn’t quite as sharp, he continued to demonstrate the plus control and consistent delivery that makes me believe in his future as much as any starter in the system.

7.19.2019: I was in attendance for Kirby’s second pro start in Paaco and from his pre-game bullpen through his 21 pitches (13 strikes) in the game and the postgame bully, it was easy to see some things not as noticeable in his time at Elon via video.

He pitches primarily from the first-base side of the slab and creates deception with the arm slot and by keeping his front shoulder closed until the arm is ready to explode through release. He got some gloveside run on the fastball away to RHBs in this game and hit the edges for called strikes a few times.

He didn’t throw a lot of offspeed stuff, but didn’t have to, either.

The heater hit 96 mph and sat 92-94. His delivery was clean and consistent. Kirby has a terrific foundation of command mechanics, present velocity and feel that suggest a high probability starter with perhaos No. 2 upside.

Here’s why Kirby ranks this high.


No. 11 Brandon Williamson, LHS (21)
WED: 1 IP, 0 H, 0 R, 0 BB, 2 SO
2019: 10 IP, 6 H, 2 ER, 4 BB, 15 SO


No. 18 Damon Casetta-Stubbs, RHS (19)
WED: DNP
2019: 95.2 IP, 97 H, 37 BB, 88 SO


No. 19 Juan Then, RHP (19)
WED: DNP
2019: 27.1 IP, 21 H, 11 ER, 7 BB, 27 SO


No. 28 Carter Bins, C (20)
WED: 0-3, SO, HBP
2019: .190/.391/.345, 5 HR, 26 BB, 42 SO

Bins fell a few spots. Here’s why.


No. 30 Jorge Benitez, LHS (20)
WED: DNP
2019: 41.1 IP, 35 H, 21 ER, 27 BB, 43 SO


No. 32 Brayan Perez, LHS (18)
WED: DNP
2019: 45.1 IP, 50 H, 20 ER, 11 BB, 39 SO


Arizona Mariners (R) — Arizona Rookie League

WED: DNP
2019: 30.1 IP, 25 H, 14 ER, 16 BB, 41 SO


No. 26 Juan Querecuto, SS (18)
WED: 0-2, 2 BB, SO
2019: 11-65, 3-2B, 8 BB, 26 SO

Querecuto has been finding the barrel a little more of late, but the bat remains unrefined. He’ll be 19 in September.

The shortstop is 11 for his last 35.


No. 34 Dutch Landis, RHP
WED: DNP
2019: 6 IP, 7 H, 3 ER, 5 BB, 4 SO


No. 39 Tyler Driver, RHP (18)
WED: DNP
2019: 41 IP, 37 H, 21 ER, 11 BB, 30 SO


UR Adam Macko, LHS
WED: 3 IP, 3 H, ER, 2 BB, 7 SO
2019: 17.1 IP, 12 H, 6 ER, 12 BB, 25 SO


UR Elvis Alvarado, RHP
WED: DNP
2019: 4 IP, 4 H, ER, BB, 5 SO

Alvarado was acquired with Guilbeau and Fletcher from the Washington Nationals in the Roenis Elias-Hunter Strickland deal last week.


DSL Mariners (R) — Dominican Summer League

No. 9 Noelvi Marte, SS (17)
WED: 2-4, HR, RBI, BB, SO, 2 SB
2019: .276/.340/.448, 13-2B, 3-3B, 7 HR, 39 RBI, 25 BB, 53 SO, 16 SB


No. 38 Jonatan Clase, CF (17)
WED:
DNP
2019:
.303/.422/.449, 11-2B, 6-3B, 2 HR, 21 RBI, 39 BB, 48 SO, 26 SB

Clase is dealing with a minor injury, I’m told, which is why he’s been out of the lineup for a few days.
