Former Jacksonville Jumbo Shrimp right-handed pitcher Jack Ralston was named an International League All-Star, Minor League Baseball announced Sept. 27, 2026.
Ralston appeared in 39 games for Jacksonville and went 6-2 with a 1.66 ERA. He pitched 59.2 innings, allowed 33 hits and recorded 75 strikeouts against 29 walks. Ralston was 29 years old at the time of the announcement and is a native of Valencia, Calif.
Ralston led qualified International League pitchers in three categories
Among 173 International League pitchers with at least 50.0 innings in 2026, Ralston ranked first in ERA, hits allowed and batting average against. Opponents hit .156 against him, while his 1.04 WHIP ranked second.
Ralston also ranked 10th among the qualified pitchers with a 31.1 percent strikeout rate. His Jacksonville season included the league’s top marks in several key pitching categories.
Ralston moved from Jacksonville to the Miami Marlins
The Miami Marlins added Ralston to their 40-man roster on Aug. 3, 2026. The Marlins recalled him Aug. 23, and he made his major league debut that day with two scoreless innings against the Washington Nationals at loanDepot park in Miami.
As of the source publication, Ralston had pitched in 16 games for the Miami Marlins and recorded 19 strikeouts in 17.1 innings. The St. Louis Cardinals selected him in the seventh round of the 2019 draft out of UCLA.
Ralston reached Triple-A Memphis during his seven years in the St. Louis Cardinals organization before electing free agency after the 2025 season. The Miami Marlins signed him to a minor league deal in December.
Jacksonville has an International League All-Star in consecutive seasons
Ralston’s selection gives the Jacksonville Jumbo Shrimp an International League All-Star in consecutive seasons. Left-handed pitcher Robby Snelling earned the honor after the 2025 season.
The Jacksonville Jumbo Shrimp are the Triple-A affiliate of the Miami Marlins and compete in the International League. The team plays its home games at VyStar Ballpark in Jacksonville, Fla.
FSB Take
Ralston’s Jacksonville numbers provide the clearest measure of his All-Star season. He led qualified International League pitchers in ERA, hits allowed and batting average against while ranking second in WHIP. His selection also continues Jacksonville’s run of consecutive-season International League All-Star honors.
