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

Tacoma Rainiers (AAA)– Pacific Coast League

No. 7 Jake Fraley, OF (24)
FRI: 0-2, 2 RBI, HBP, SO
2019: .296/.364/.535, 24-2B, 5-3B, 17 HR, 76 RBI, 33 BB, 84 SO, 22 SB


No. 12 Shed Long, 2B/3B/OF (23)
FRI: DNP (IL)
2019: .279/.343/.466, 7-2B, 4-3B, 8 HR, 35 RBI, 20 BB, 59 SO


No. 14 Braden Bishop, CF (25)
FRI: Recalled 6.2.2019 (IL)
2019: .293/.378/.500, 13-2B, 7 HR, 29 RBI, 21 BB, 38 SO, 2 SB


No. 27 Erik Swanson, RHS (25)
FRI: Recalled 7.16.2019
2019: 10 G, 6 GS, 24.1 IP, 28 H, 15 ER, 12 BB, 28 SO


No. 35 David McKay, RHR (24)
FRI: 1 IP, H, ER, 0 BB, 2 SO
2019: 28 G, 41.2 IP, 25 H, 30 BB, 69 SO


No. 36 Tim Lopes, 2B (24) [REHAB]
FRI: 3-4, SB
2019: .307/.366/.483, 30-2B, 2-3B, 10 HR, 60 RBI, 35 BB, 68 SO, 25 SB


UR Taylor Guilbeau, LHP
FRI: 1 IP, H, 0 R, 0 BB, 2 SO
2019: 35 G, 44.2 IP, 38 H, 14 ER, 15 BB, 52 SO

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.


Arkansas Travelers (AA) — Texas League

No. 2 Logan Gilbert, RHS (22)
FRI: DNP
2019: 101.1 IP, 71 H, 26 ER, 25 BB, 126 SO


No. 3 Justin Dunn, RHS (23)
FRI: DNP
2019: 100.1 IP, 91 H, 41 ER, 31 BB, 119 SO


No. 5 Justus Sheffield, LHS (23)
FRI: DNP
2019: 115.1 IP, 107 H, 55 BB, 113 SO

8.1.2019: Sheffield has been good in Arkansas, making nine starts and covering 60 1/3 innings — 5.1 more than he managed in 13 outings for Triple-A Tacoma — while walking just 14 batters. He’s whiffed 65 and, most importantly, found his release point on the fastball.


No. 9 Kyle Lewis, OF (24)
FRI: 2-4
2019: .276/.365/.414, 22-2B, 2-3B, 8 HR, 52 RBI, 51 BB, 112 SO, 3 SB


No. 10 Cal Raleigh, C (22)
FRI: 1-4, 2B, RBI, 3 SO
2019: .249/.329/.490, 21-2B, 22 HR, 71 RBI, 41 BB, 91 SO


No. 11 Evan White, 1B (23)
FRI: DNP
2019: .291/.342/.484, 12-2B, 2-3B, 13 HR, 42 RBI, 21 BB, 66 SO, SB


No. 17 Ricardo Sanchez, LHS (22)
FRI: DNP
2019: 113.2 IP, 126 H, 53 ER, 29 BB, 114 SO


No. 18 Ljay Newsome, RHS (22)
FRI: 5 IP, 4 H, ER, BB, 2 SO
2019: 22 GS, 122 IP, 127 H, 51 ER, 12 BB, 140 SO


No. 22 Dom Thompson-Williams, OF (24)
FRI: 0-5, 3 SO
2019: .232/.301/.4395, 21-2B, 3-3B, 10 HR, 35 RBI, 30 BB, 120 SO, 14 SB

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


No. 24 Jake Haberer, RHR (24)
FRI: DNP
2019: 31 G, 43 IP, 32 H, 25 BB, 61 SO

7.29.2019: In his last nine appearances, Haberer has tossed 12.2 innings and allowed just two earned runs — both came in the same outing. He’s struck out 18 in that span and walked seven — four of those came in a single game.

Consistency with control and command seem to the only issue for Haberer at this stage. The fastball and breaking both meet major lague requirements.


No. 26 Joey Gerber, RHP (22)
FRI: 1 IP, 0 H, 0 R, 0 BB, SO
2019: 35 G, 38.1 IP, 26 H, 13 ER, 20 BB, 53 SO


No. 30 Sam Delaplane, RHR (24)
FRI: DNP
2019: 35 G, 53 IP, 31 H, 21 BB, 95 SO

8.1.2019: Delaplane threw 15 of 21 pitches for strikes to cruise through the final two innings of Sheffield’s fine outing Thursday.

7.29.2019: Scouts tell me Delaplane’s fastball hasn’t had quote the zip it had earlier in the year, which might explain a tad plunge in production as well as usage. No sign of injury at all, it may just be that time of year. He’s pitched a lot.


No. 34 Wyatt Mills, RHR (24)
FRI:
DNP
2019:
31.2 IP, 36 H, 19 ER, 14 BB, 49 SO

7.31.2019: Mills has yielded runs in just one outing since June 19 and has pitched nine clean appearances in that span, posting 21 strikeouts and just two bases on balls in 14 innings.

After starting the year slow, Mills has been consistently 91-94, touching 95 with late life to his arm side and sink down in the zone. Ground balls. Strikeouts. That’s his game.


No. 39 Donnie Walton, 2B/SS (25)
FRI: 2-5, 2B
2019: .291/.389/.412, 13-2B, 3B, 10 HR, 52 BB, 58 SO, 8 SB


UR Aaron Fletcher, LHP
FRI: 1 IP, 0 H, 0 R, 0 BB, 3 SO
2019: 33 G, 61.1 IP, 37 H, 12 ER, 15 BB, 72 SO


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

No. 1 Jarred Kelenic, OF (20)
FRI: 2-5, RBI, 2 SO
2019: .287/.369/.527, 25-2B, 4-3B, 16 HR, 47 RBI, 42 BB, 89 SO, 16 SB


No. 40 Raymond Kerr, LHP (24)
FRI: 2 IP, H, 0 R, BB, 3 SO
2019: 27 G, 79 IP, 74 H, 41 BB, 74 SO

Kerr is due a promotion. He’s been nasty for awhile now, allowing one earned run in his last 24.2 innings (since June 23). During that span he’s yielded 11 hits and eight walks, while whiffing 29. He’s often gone more than an inning — nine times in 13 outings — with eight of those going at least two innings.


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

No. 4 — Julio Rodriguez, OF (18)
FRI: 2-4, 3B, 2 RBI, SO
2019: .272/.343/.475, 15-2B, 3B, 9 HR, 40 RBI, 16 BB, 59 SO


No. 20 Austin Shenton, 3B (21)
FRI: 2-3, 2B, HR, 3 RBI
2019: .317/.394/.583, 15-2B, 2-3B, 6 HR, 31 RBI, 14 BB, 32 SO

Shenton six for his last 11 with two homers and four doubles.


UR Josias De Los Santos, RHP (19)
FRI: DNP
2019: 16 G, 11 GS, 74.2 IP, 75 H, 28 BB, 58 SO


Everett SquaSox (SS-A) — Northwest League

No. 6 George Kirby, RHS (21)
FRI: 1 IP, H, 0 R, 0 BB, 3 SO
2019: 4 GS, 10 IP, ER, 0 BB, 7 SO

Kirby was named to the NWL All-Star team Wednesday.

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.


No. 15 Brandon Williamson, LHS (21)
FRI: DNP
2019: 8 IP, 6 H, 2 ER, 4 BB, 14 SO


No. 19 Damon Casetta-Stubbs, RHS (19)
FRI: DNP
2019: 91.2 IP, 95 H, 35 BB, 81 SO

Casetta-Stubbs was named to the NWL All-Star team Wednesday.


No. 21 Juan Then, RHP (19)
FRI: DNP
2019: 19 IP, 14 H, 5 ER, 3 BB, 21 SO


No. 25 Carter Bins, C (20)
FRI: DNP
2019: .176/.375/.294, 4 HR, 25 BB, 40 SO


No. 29 Brayan Perez, LHS (18)
FRI: DNP
2019: 41.1 IP, 45 H, 20 ER, 11 BB, 39 SO


No. 31 Jorge Benitez, LHS (20)
FRI: DNP
2019: 36.2 IP, 33 H, 16 ER, 23 BB, 40 SO


Arizona Mariners (R) — Arizona Rookie League

No. 23 Juan Querecuto, SS (18)
FRI: 1-4, RBI, 3 SO
2019: 4-32, 5 BB, 16 SO


No. 28 Danny Chang, LHP (19)
FRI: 4 IP, 3 H, ER, BB, 6 SO
2019: 30.1 IP, 25 H, 14 ER, 16 BB, 41 SO


No. 37 Tyler Driver, RHP (18)
FRI: 3 IP, 4 H, 4 ER, 3 BB, SO
2019: 34 IP, 33 H, 18 ER, 10 BB, 25 SO


NOTE: Jose Caballero, acquired from the Arizona Diamondbacks in exchange for Mike Leake and cash on Deadline Day, went 2-for-5 with a double in Game 2 of his Mariners org career.

He’s likely to work his way up to Modesto soon.


DSL Mariners (R)

No. 8 Noelvi Marte, SS (17)
FRI: 3-4, 2B
2019: .264/.330/.415, 11-2B, 3-3B, 4 HR, 31 RBI, 21 BB, 46 SO, 12 SB

Marte has been in a slump the past few weeks — he has six hits in his last 34 at-bats in his past nine games — but I’m told he’s showing improvement in the field; a lot of it is recognizing situations where he has to get rid of the ball quickly versus taking his time, or making the sure play.


No. 38 Jonatan Clase, CF (17)
FRI:
1-3. RBI
2019:
.301/.419/.466, 11-2B, 6-3B, 2 HR, 18 RBI, 34 BB, 41 SO, 22 SB
