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

Tacoma Rainiers (AAA)– Pacific Coast League

No. 7 Jake Fraley, OF (24)
THU: DNP
2019: .295/.363/.534, 24-2B, 5-3B, 17 HR, 76 RBI, 33 BB, 85 SO, 22 SB


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


No. 14 Braden Bishop, CF (25)
THU: 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)
THU: Recalled 7.16.2019
2019: 10 G, 6 GS, 24.1 IP, 28 H, 15 ER, 12 BB, 28 SO


No. 36 Tim Lopes, 2B (24) [REHAB]
THU: DNP
2019: .301/.361/.474, 30-2B, 2-3B, 10 HR, 60 RBI, 36 BB, 70 SO, 26 SB


UR Taylor Guilbeau, LHP
THU: 1.1 IP, H, 0 R, 0 BB, SO
2019: 37 G, 47 IP, 40 H, 14 ER, 15 BB, 54 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.


Arkansas Travelers (AA) — Texas League

No. 2 Logan Gilbert, RHS (22)
THU: 5 IP, 3 H, ER, BB, 8 SO
2019: 112.2 IP, 80 H, 29 ER, 26 BB, 138 SO

8.8.2019: Gilbert was terrific Thursday, perhaps his best start from a scouting standpoint since he was promoted to Double-A Arkansas five weeks ago.

The right-hander induced 15 swing-and-miss results among his 84 pitches (57 strikes), getting a few with the fastball, several with the two breaking balls and two with the changeup.

Two of his eight strikeouts came again rehabbing major leaguer Yadier Molina.

That’s five start for Gilbert at Double-A and all have lasted at least five innings.


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


No. 5 Justus Sheffield, LHS (23)
THU: DNP
2019: 121.1 IP, 111 H, 55 BB, 119 SO

8.6.2019: Sheffield has been good in Arkansas, making 10 starts and covering 66.1 innings — 11.1 more than he managed in 13 outings for Triple-A Tacoma — while walking just 14 batters. He’s whiffed 71 and, most importantly, found his release point on the fastball.

In Tuesday’s game Sheffield sat 91-92 mph, touched 93 several times and used his slider early in counts. He flashed a utility changeup


No. 9 Kyle Lewis, OF (24)
THU: 1-4
2019: .274/.358/.407, 23-2B, 2-3B, 8 HR, 53 RBI, 51 BB, 118 SO, 3 SB


No. 10 Cal Raleigh, C (22)
THU: 1-4, HR, RBI, SO
2019: .259/.340/.505, 22-2B, 24 HR, 74 RBI, 45 BB, 97 SO


No. 11 Evan White, 1B (23)
THU: 1-5, HR, 2 RBI, 3 SO
2019: .288/.336/.482, 12-2B, 2-3B, 14 HR, 45 RBI, 21 BB, 72 SO, SB


No. 17 Ricardo Sanchez, LHS (22)
THU: DNP
2019: 120.2 IP, 129 H, 54 ER, 30 BB, 117 SO


No. 18 Ljay Newsome, RHS (22)
THU: DNP
2019: 23 GS, 128 IP, 129 H, 51 ER, 13 BB, 143 SO


No. 22 Dom Thompson-Williams, OF (24)
THU: 1-3, HR, RBI, BB
2019: .234/.304/.402, 22-2B, 3-3B, 11 HR, 38 RBI, 32 BB, 123 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)
THU: DNP
2019: 33 G, 45.2 IP, 34 H, 27 BB, 64 SO


No. 26 Joey Gerber, RHP (22)
THU: DNP
2019: 36 G, 39.1 IP, 26 H, 13 ER, 20 BB, 55 SO

THU: 2-3, 2 BB
2019: .293/.391/.410, 14-2B, 3B, 10 HR, 55 BB, 58 SO, 8 SB


UR Aaron Fletcher, LHP
THU: 2.1 IP, 2 H, 0 R, 0 BB, 3 SO
2019: 34 G, 63.2 IP, 39 H, 12 ER, 15 BB, 75 SO


Modesto Nuts (A+) — California League

No. 1 Jarred Kelenic, OF (20)
THU: 3-5, HR, 2 RBI, SO
2019: .301/.376/.540, 27-2B, 4-3B, 17 HR, 51 RBI, 42 BB, 93 SO, 17 SB

Kelenic batted .284/.384/.500 in July after a poor 16-game June, but is 15 for 30 with three doubles and a homer in August.


No. 40 Raymond Kerr, LHP (24)
THU: DNP
2019: 28 G, 80 IP, 75 H, 43 BB, 75 SO


West Virginia Power (A) — South Atlantic League

No. 4 Julio Rodriguez, OF (18)
THU: 2-4, SO
2019: .285/.353/.477, 17-2B, 3B, 9 HR, 41 RBI, 18 BB, 62 SO

Rodriguez, who won’t be 19 until December 29, is up to .357/.436/.599 over his last 10 games.

He’s hitting velocity, too.


No. 20 Austin Shenton, 3B (21)
THU: 0-4
2019: .304/.381/.538, 15-2B, 2-3B, 6 HR, 33 RBI, 15 BB, 35 SO


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


UR Ryne Inman, RHP
THU: 9 IP, 3 H, 0 R, 0 BB, 12 SO
2019: 24 GS, 121 IP, 46 BB, 136 SO

The 23-year-old continues to flash potential major-league stuff but I still see it coming in a relief form. The fastball is up to 95 mph and the curveball is consistently average or better. He’s 6-foot-5 and 215 pounds, there’s some deception in the delivery and late life on the fastball. In shorter stints he may ultimately live at 95 and touch the upper-90s. Make the move.


Everett SquaSox (SS-A) — Northwest League [ALL-STAR BREAK]

No. 6 George Kirby, RHS (21)
THU: DNP
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)
THU: DNP
2019: 8 IP, 6 H, 2 ER, 4 BB, 14 SO


No. 19 Damon Casetta-Stubbs, RHS (19)
