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

Tacoma Rainiers (AAA)– Pacific Coast League

No. 5 Justus Sheffield, LHS
WED: DNP
2019: 54.1 IP, 52 H, 27 ER, 40 BB, 46 SO, 5.74 ERA

6.7.2019: Hot and cold for Sheffield, and far too much cold. At this point, I wonder if Sheffield doesn’t get skipped in the rotation once or twice if they’re working on some mechanical adjustments, because he’s just not finding a consistent release point. The stuff is fine. He’s missing bats. The changeup isn’t being used a lot but he’s not getting into a lot of changeup counts, either.


NEW: Top 40 Prospect Rankings Update


No. 9 Shed Long, 2B/3B/OF
WED: Recalled 5.21.2019

WED: DNP
2019: 17 G, 5.26 ERA, 25.2 IP, 19 H, 19 BB, 40 SO


No. 32 Tim Lopes, 2B
WED: 1-5, 2 SO
2019: .305/.357/.471, 20-2B, 3B, 5 HR, 34 RBI, 20 BB, 44 SO, 14 SB

No. 7 Kyle Lewis, OF
WED: 0-3, BB, 3SO
2019: .248/.341/.374, 11-2B, 2-3B, 4 HR, 37 RBI, 31 BB, 69 SO, 2 SB


No. 11 Jake Fraley, OF
WED: 0-1, SO
2019: .326/.393/.563, 14-2B, 2-3B, 11 HR, 45 RBI, 19 BB, 46 SO, 14 SB

Fraley didn’t even finish his PA in this game as he fouled a ball off his leg (knee?) and couldn’t continue. He limped off on his own, though, so perhaps that’s a good sign.


No. 14 Evan White, 1B
WED: 2-4, HR, SO
2019: .290/.363/.463, 5-2B, 3B, 7 HR, 20 RBI, 17 BB, 39 SO, SB

WED: 3 IP, 7 SO
2019: 23 G, 35.2 IP, 22 H, 15 BB, 75 SO, 2 SVS

Delaplane has face 16 batters in Double-A and struck out 12 of them. 91-95 mph, sink, life up in zone, short, tight curveball, 55 command, 60 control.

He’s whiffed over 50% of the batters he’s faced this season with a 25% swinging strike rate.


Modesto Nuts (A+) — California League

No. 1 — Jarred Kelenic, OF
WED: DNP
2019: .316/.398/.595, 15-2B, 3-3B, 13 HR, 34 RBI, 27 BB, 50 SO, 10 SB

WED: 5 IP, 6 H, 2 ER, 0 BB, 9 SO
2019: 14 GS, 77 IP, 81 H, 30 ER, 9 BB, 103 SO, 3.51 ERA

Newsome threw 63 of 85 pitches for strikes and surpassed the 100-strikeout mark. It’s the sixth time in 14 starts Newsome has fanned at least nine batters.  It was the eighth time he’s avoided the walk in an outing.

Newsome also has gone five innings or more in all but two starts, including seven starts of at least six innings. He also has a seven-inning start and one then went eight frames, yet he’s still somehow not thrown more than 97 pitches in game in 2019.

The 22-year-old has thrown 72.3% of his pitches for strikes this season.


No. 28 Joey Gerber, RHP
WED: DNP
2019: 19 G, 21 IP, 15 H, 8 ER, 8 BB, 32 SO

Crawford is expected to get 12-15 ABs or so and be activated, barring any setbacks. His long ball Tuesday came on a 3-2 fastball middle-in.


West Virginia Power (A) — South Atlantic League

No. 4 — Julio Rodriguez, OF
WED: 0-4, SO
2019: .293/.396/.390, 4-2B, 3 RBI, 6 BB, 6 SO


No. 25 Damon Casetta-Stubbs, RHS

No. 8 Noelvi Marte, SS
WED: 0-4, BB, 3 SO
2019: .278/.325/.444, 2B, 3B, HR, 5 RBI, 3 BB, 9 SO, 2 SB

Marte will not be 18 until October, so like with Julio Rodriguez last year Marte is on pace to hit the states for full-season ball in 2020.


UR Arturo Guerrero, OF
WED: 0-2, BB, HBP, 2 SO, SB
2019: .296/.457/.444, 2B, HR, 4 BB, 11 SO, 4 SB

Guerrero is a 6-foot-3, 170-pound outfielder with plus speed and above-average tools across the board. He’s a right-handed batter who will turn 19 in September.


UR Milkar Perez, 3B
WED: 0-4, SO
2019: .172/.294/.276, 4 BB, 10 SO

The 5-foot-11, 175-pound Perez has mature plate skills and the ability to use most of the field. He’s a right-handed batter and is from Nicaragua. He will be 18 in October.


UR Luis Baez, RHP
WED: 5 IP, 4 H, ER, 2 BB, 2 SO
2019: 2 GS, 8 IP, 7 H, 3 ER, 4 BB, 3 SO

Baez was my No. 25 prospect to start the year because the club lacked upside plays anywhere else, then the right-hander faded out of the ranking as some of the clubs winter adds established themselves, including McKay, Haberer and a few others.

He’s 6-foot-3 and 170 pounds, offering physical projection and he’s shown good ability to manipulate the baseball, both with a sinking fastball and with two different breaking balls and a changeup.


UR Jonatan Clase, CF
WED: 2-3, BB, SO, 3 SB
2019: .290/.425/.419, 2B, HR, 6 BB, 8 SO, 5 SB

Clase is 5-foot-8, 160 pounds and packs a quick left-handed swing with some torque and loft. He just turned 17 May 23.


UR Asdrubal Bueno, SS
WED: 0-3
2019: .333/.429/.625, 2B, 2 HR, 5 RBI, 4 BB, 5 SO

Bueno is a right-handed hitter out of Venezuela. He’s 5-foot-11, 177 pounds and has good bat speed and an aggressive game plan. He will turn 18 in November.


UR Jose Caguana, C
WED: 1-4, SO
2019: .292/.320/.333, 2B, BB, 6 SO

Caguana is a right-handed hitting backstop from Venezuela. He just turned 17 in April and stands 5-foot-10 and 182 pounds.


UR Abdiel Medina, RHP
WED: 1 IP, SO
2019: 3 G, 6.2 IP, 7 H, 4 ER, 5 BB, 9 SO

Medina is a 5-foot-11, 165-pound right-hander from Panama. He’s a fastball-curveball-changeup arm ith a live arm and some feel for the secondaries. The heater has touched 87 mph. He turned 17 in January.


UR Yeury Tatiz, RHP
WED: DNP
2019: 2 GS, 9 IP, 6 H, 2 ER, BB, 11 SO

Tatiz stands a projectable 6-foot-3 and 178 pounds with some buggy whip in the arm action and stuff with promise, including a fastball up to 91 mph and a developing breaking ball. He’ll be 19 in November.


UR Wilton Perez, RHP
WED: DNP
2019: 2 GS, 7.1 IP, 9 H, 2 ER, 2 BB, 7 SO
