Born on May 14, 1994, in Vacaville, California, Gonsolin has built his career in Major League Baseball (MLB) with the Los Angeles Dodgers after a notable college stint with the Saint Mary’s Gaels. He was drafted by the Dodgers in the ninth round of the 2016 MLB draft, debuted in the majors in 2019, and was selected as an MLB All-Star in 2022. He was a key contributor to the Dodgers’ World Series championship in 2020.
Across his MLB tenure, Gonsolin has been recognized for his poise on the mound, his late-inning reliability, and his role in one of the most successful eras of Dodgers baseball. Although injuries have interrupted several seasons, he remains a respected figure in the sport and continues to attract attention as a free agent.
Early Life and Background
Anthony Dennis Gonsolin was born on May 14, 1994, in Vacaville, California, where he spent his formative years. He attended Vacaville High School and developed his baseball skills on local fields. As a senior at Vacaville, he posted a 4–1 record with a 2.60 earned run average (ERA), signaling early promise as a pitcher. Despite his high-school performance, he went undrafted in the 2012 MLB draft.
After high school, Gonsolin chose to play college baseball at St. Mary’s College of California, representing the Saint Mary’s Gaels. In summer 2015, he gained additional experience as a member of the Madison Mallards in the Northwoods League, a respected collegiate summer circuit. As a senior in 2016, he recorded a 3–3 record with a 3.86 ERA across 18 games, finishing his amateur career on a steady note before entering the professional ranks.
Path to Baseball
Gonsolin’s professional path began when the Los Angeles Dodgers selected him in the ninth round of the 2016 MLB draft. He started his first professional season with the rookie-level Ogden Raptors and the Single-A Great Lakes Loons, combining for a 1–2 record with a 3.77 ERA and 25 strikeouts across 19 relief appearances. In 2017, he advanced to the High-A Rancho Cucamonga Quakes, posting a 7–6 record with a 3.86 ERA and 85 strikeouts in 42 games.
His breakout in the minors came in 2018, when the Dodgers converted Gonsolin from a reliever into a starting pitcher. He split that year between Rancho Cucamonga and the Double-A Tulsa Drillers, going 10–2 with a 2.60 ERA and 155 strikeouts in 128 innings across 26 starts. That performance earned him the Dodgers’ organization-wide minor league pitcher of the year award for 2018 and positioned him for a major league call-up the following season.
Tony Gonsolin Career
Early Career (2019)
Gonsolin opened 2019 with the Triple-A Oklahoma City Dodgers before receiving his first big-league call-up on June 26, 2019, starting against the Arizona Diamondbacks. He pitched four innings in his debut, allowing six runs (four earned) on six hits with three strikeouts, and also recorded his first major league hit with a single to center field. He earned his first career save on July 30 in relief against the Colorado Rockies and notched his first win on August 5 by throwing six shutout innings against the St. Louis Cardinals, allowing two hits and one walk while striking out seven.
Across 11 games that year (six starts), Gonsolin compiled a 4–2 record with a 2.93 ERA in 40 innings, a strong introduction to the majors that set the tone for his role in the Dodgers’ pitching staff.
Dodgers Breakthrough (2020–2021)
During the pandemic-shortened 2020 regular season, Gonsolin went 2–2 with a 2.31 ERA, striking out 46 batters in 46⅔ innings across nine games (eight starts). In the postseason, he started Game 2 of the National League Championship Series (NLCS) and appeared in relief in Game 7, and was then chosen by Dodgers manager Dave Roberts to start Game 2 of the World Series against the Tampa Bay Rays. He also started Game 6 of the World Series, where the Dodgers rallied to clinch the championship. He finished fourth in the 2020 National League Rookie of the Year voting and was named 2020 Rookie of the Year by Baseball America.
In 2021, Gonsolin made 13 starts and two relief appearances, finishing 4–1 with a 3.23 ERA. The season was interrupted twice by right shoulder inflammation, with stints on the injured list in April and again in late July before he returned in September. He made three relief appearances in the 2021 NLCS, allowing five runs on five hits in four innings.
All-Star Season (2022)
Gonsolin opened the 2022 season in dominant form, going 11–0 with a 2.02 ERA and earning a selection to the 2022 Major League Baseball All-Star Game. He took the loss in the All-Star Game, allowing three runs on four hits including two home runs. A forearm strain in late August landed him on the injured list until October 3. Even with the late setback, he finished 16–1 with a 2.14 ERA and 119 strikeouts, both career bests. He started Game 3 of the National League Division Series (NLDS) against the San Diego Padres, took the loss, and watched the favored Dodgers exit in the series.
Dodgers Return (2023–2025)
On January 31, 2023, Gonsolin signed a two-year, $6.65 million contract to avoid salary arbitration. A spring-training ankle injury delayed his season debut until April 26, and he went on to make 20 starts with an 8–5 record and a 4.98 ERA. On August 18, 2023, he allowed 10 earned runs and five home runs in 3⅓ innings against the Miami Marlins, tying a team record for most home runs allowed in a game. He was placed on the injured list the next day with right forearm inflammation, and Tommy John surgery on August 28 ended his 2023 campaign.
Gonsolin spent 2024 rehabbing in the minors with three rehab appearances. He signed a $5.4 million contract with the Dodgers for 2025 to avoid salary arbitration, but a back injury from lifting weights in spring training delayed his debut. He rejoined the rotation on April 30, made seven starts at 3–2 with a 5.00 ERA, and was placed back on the injured list on June 7 with right elbow discomfort. On August 12, the team confirmed he had undergone internal brace and flexor repair surgery on his shoulder, ending his 2025 season. The Dodgers designated him for assignment on November 6, 2025, and he cleared waivers and elected free agency on November 12, 2025.
