For many players within the Marlins organization, baseball never stops. Just like last year, Fish Stripes will be consistently updating the whereabouts of your favorite Fish during the offseason. At, you can find updates on them, including stats, highlights and (small sample size) analysis.

Arizona Fall League

Fall ball finished a while ago, but MLB Pipeline recently rolled out several pieces of recap content worth passing along.

Jim Callis ranks Nick Neidert as the 25th-best prospect who participated in the league (and the best in the Marlins’ delegation). He still figures to remain on the outside looking in when the site releases its next MLB Top 100 prospects update. Lights-out reliever Alex Vesia earned MLB Pipeline All-AFL Second Team recognition. C.J. Carter showed elite spin rate on his curveball, topping 3,000 RPM in every appearance and maxing out at 3,181 RPM—to put that in perspective, Austin Brice had the fastest-spinning curve on the Marlins staff this season, according to Statcast (2,903 RPM).

Dominican Winter League

  • C Wilkin Castillo—.273/.320/.273, 3 RBI, 1 SB, 5 K in 22 AB
  • 1B Lewin Díaz—.280/.337/.467, 3 HR, 11 RBI, 12 K in 75 AB
  • 3B/SS Joe Dunand—.158/.238/.316, 2 RBI, 5 K in 19 AB
  • OF Gabriel Guerrero—.125/.125/.125, 2 RBI, 7 K in 16 AB
  • RHP Tayron Guerrero—3.18 ERA, 1.57 WHIP, 7 K in 5.2 IP
  • RHP Kolton Mahoney—4.97 ERA, 1.74 WHIP, 13 K in 12.2 IP (3 GS)
  • 1B/OF Peter O’Brien—.286/.432/.524, 3 HR, 14 RBI, 22 K in 63 AB
  • RHP Cody Poteet—13.50 ERA, 2.55 WHIP, 4 K in 6.2 IP (3 GS)
  • OF Magneuris Sierra—.227/.261/.227, 2 SB, 3 K in 22 AB

Hardly any production from Sierra at the plate lately, but at least he’s flashing the wheels!

O’Brien remains a legitimate candidate in the way-too-early LIDOM MVP conversation. He’s been splitting time evenly between first base and right field.

With help from both Sierra and O’Brien, Toros del Este set a franchise record with an 11-game winning streak, surging up to second place in the league standings. It finally ended on Monday.

Dunand’s Leones de Escogido are sitting in first place. In this new interview, he discusses the experience so far and his relationship with uncle Alex Rodriguez, also saying that there is no set date for him to leave the team. The former second-round MLB Draft pick played sparingly last week because he had a family engagement back in the U.S.

Águilas Cibaeñas released Cody Poteet to make room on their roster for another pitcher. As mentioned previously, Poteet will be eligible for the Rule 5 Draft, but struggles at both Triple-A and now LIDOM may scare away other teams from selecting him.

Mexican Pacific League


Team Canada began their WBSC Premier12 tournament experience with training camp and a pair of exhibitions in Japan. Tristan Pompey was in the lineup (alongside his older brother and former major leaguer, Dalton).

Their real games get underway 10 p.m. ET on Tuesday in South Korea.

Pompey will try to shake off a miserable 2019 regular season, during which he slashed .194/.295/.271 with a 34.9% strikeout rate for High-A Jupiter. Multiple lower-body injuries limited him to 42 games.
