Logan Gilbert Bio
Logan Keith Gilbert is an American professional baseball pitcher for the Seattle Mariners of Major League Baseball (MLB). The right-hander made his MLB debut in 2021 and earned an All-Star selection in 2024. Gilbert has developed into one of the most durable starters in the American League, known for his command, deep pitch counts, and ability to limit walks and hits.
Standing 6 feet 6 inches tall, Gilbert pairs an unusually long release with a deep pitch mix that has steadily expanded since his arrival in the majors. He has anchored the top of the Mariners rotation, started multiple postseason games, and helped lead Seattle back to playoff contention after a long absence.
Early Life and Background
Logan Keith Gilbert was born on May 5, 1997, and grew up in Florida. He attended Wekiva High School in Apopka, where he pitched and played first base. He was named his team’s Most Valuable Player as a senior, and he reached 90 miles per hour on his fastball in 2014. Perfect Game rated him the 500th best high school prospect in 2015, but he went undrafted and committed to Stetson University to continue his baseball career.
At Stetson, Gilbert joined a Hatters program in DeLand, Florida, and quickly became a frontline starter. He also has an older brother who pitched in high school before an elbow injury ended his playing career. Gilbert has spoken about his Christian faith as an important part of his life.
Path to Baseball
Gilbert starred in the Atlantic Sun Conference during his three years at Stetson. As a freshman in 2016, he appeared in 21 games and posted a 2.74 earned run average, then spent the summer with the Bethesda Big Train of the Cal Ripken Collegiate Baseball League. He broke out as a sophomore in 2017, going 10–0 with a 2.02 ERA and 107 strikeouts, and was named the ASUN Pitcher of the Year. That summer, he played for the Orleans Firebirds of the Cape Cod Baseball League and earned all-star honors.
As a junior in 2018, Gilbert went 11–2 with a 2.72 ERA and repeated as the ASUN Pitcher of the Year. He was widely viewed as one of the top 20 prospects for the 2018 MLB Draft. The Seattle Mariners selected him 14th overall and signed him to a $3.88 million bonus. His promising first professional summer was cut short when he contracted mononucleosis, but his trajectory remained clear.
Logan Gilbert Career
Early Career (2018–2020)
Gilbert began his professional career in the Mariners system in 2019, opening the year as the starting pitcher on Opening Day for the West Virginia Power of the Low-A South Atlantic League. He went 1–0 with a 1.59 ERA in five starts before being promoted to the High-A Modesto Nuts, where he went 5–3 with a 1.73 ERA and 73 strikeouts in 62+1⁄3 innings. He finished the year with the Double-A Arkansas Travelers, going 4–2 with a 2.88 ERA across nine starts.
Gilbert did not appear in an official game in 2020 because the minor league season was canceled due to the COVID-19 pandemic. He spent time at the Mariners’ alternate training site in Tacoma and pitched in an intrasquad exhibition game at T-Mobile Park in Seattle during the summer.
MLB Debut Season (2021)
Entering 2021, Gilbert was a consensus top 40 prospect. He began the year with the Triple-A Tacoma Rainiers, earning a win in his only start, and was promoted to Seattle on May 13. He debuted that day against the Cleveland Indians, taking the loss after allowing four runs in four innings. He earned his first career MLB win on June 6 against the Los Angeles Angels, striking out seven across five innings of one-run ball. Gilbert finished his rookie season 6–5 in 24 starts with a 4.68 ERA and 128 strikeouts in 119+2⁄3 innings.
Breakout Season (2022)
Gilbert took a major step forward in his first full MLB season. He was named the American League Pitcher of the Month for April 2022, going 3–0 with 22 strikeouts in 20 innings. He finished the year 13–6 with a 3.20 ERA in 32 starts covering 185+2⁄3 innings, establishing himself as a core member of the Mariners rotation.
On September 30, Gilbert allowed one run across eight innings against the Oakland Athletics, helping the Mariners clinch a playoff berth for the first time since 2001. He started Game 1 of the American League Division Series (ALDS) and left with Seattle ahead, though the team eventually lost in the bottom of the ninth inning.
2023 Season
Gilbert continued his strong work in 2023, throwing his first career shutout on July 4 against the San Francisco Giants, striking out seven and allowing five hits. He followed that with a win over the Houston Astros, earning the American League Player of the Week Award. On August 8, he struck out 12 batters in a 2–0 victory over the San Diego Padres. He finished 2023 with a 13–7 record, a 3.73 ERA, and 189 strikeouts in 190+2⁄3 innings. His 5.25 strikeout-to-walk ratio ranked third in the American League, trailing only his Mariners teammate George Kirby.
All-Star Year (2024)
Gilbert earned his first All-Star selection in 2024. He was unable to pitch in the Midsummer Classic because he was scheduled to start two days earlier, and Andrés Muñoz replaced him on the roster. On September 8, he delivered his second career complete game, going eight innings in a 2–0 loss to the St. Louis Cardinals while tying his season high with 10 strikeouts. Gilbert led the majors with 208+2⁄3 innings pitched and with a 0.887 walks and hits per inning pitched, and his 220 strikeouts ranked sixth in MLB. He finished the year 9–12 with a 3.23 ERA.
Seattle Mariners Era (2025–Present)
Gilbert was the Mariners’ Opening Day starter in 2025 against the Athletics, allowing one home run and striking out eight in a win. He landed on the 15-day injured list on April 26 after suffering a right elbow flexor strain against the Miami Marlins, missing more than seven weeks before returning on June 16 against the Boston Red Sox. He set a new career high with 13 strikeouts on August 24 against the Athletics, and closed the regular season 6–6 with a 3.44 ERA and 173 strikeouts in 131 innings, with a career-best 32.3 percent strikeout rate.
In the 2025 postseason, Gilbert started Game 3 of the ALDS against the Detroit Tigers and earned a win, returned on short rest to throw two scoreless relief innings in Game 5 to help Seattle reach the American League Championship Series (ALCS), and started Game 2 of the ALCS against Toronto. He started Game 6 of the series and took the loss, finishing the 2025 playoffs with a 4.20 ERA across four appearances. He was again the Mariners’ Opening Day starter in 2026.
Driving Style and Strengths
Gilbert’s 6-foot-6 frame and large hands create one of the longest extensions in the majors, meaning he releases the ball closer to home plate and gives hitters less time to react. He pairs that physical advantage with a deep pitch mix that has included a four-seam fastball, slider, changeup, splitter, cutter, and sinker. He learned a new slider from Jacob deGrom in 2022, added a split changeup in 2023, and introduced a cutter in 2024, constantly refining his arsenal.
Notable Events and Milestones
Gilbert’s signature moments include his 2022 outing against the Oakland Athletics that helped the Mariners clinch their first playoff berth in two decades, his first career shutout on July 4, 2023, and his 2024 All-Star selection. He also led Major League Baseball in innings pitched in 2024 and set a new career high with 13 strikeouts in 2025.
