Casey Schmitt Bio
Casey Shawn Schmitt is an American professional baseball infielder for the San Francisco Giants of Major League Baseball (MLB). Born and raised in San Diego, California, Schmitt developed into one of the top two-way players in college baseball at San Diego State University, where he served as both a relief pitcher and a third baseman. Selected by the Giants in the second round of the 2020 MLB draft, he earned a Minor League Baseball Gold Glove in 2022 as the best defensive third baseman in the minor leagues and made his major league debut in May 2023.
Early Life and Background
Schmitt was born on March 1, 1999, in San Diego, California, to parents Dan Schmitt and Tina Schmitt. He grew up alongside an older brother named Nick, and the family remained based in the San Diego area during his childhood. His early years in Southern California gave him steady exposure to year-round baseball, which helped shape his development as a two-way player on the mound and in the field.
Schmitt attended Eastlake High School in Chula Vista, California, graduating in 2017, and he was a multi-year varsity standout for the baseball team. He served as team captain in his senior season, and his high school honors included Perfect Game Underclass High Honorable Mention in 2015 and 2016, a .500 batting average as a junior, and the 2016 Mesa League Athlete of the Year award. In 2017 he was named Rawlings/Perfect Game All-America honorable mention, Perfect Game California All-Region First Team, and the third-best outfielder in California, drawing attention from college recruiters across the country.
Path to Baseball
After high school, Schmitt committed to San Diego State University, where he spent three seasons playing college baseball for the San Diego State Aztecs. He contributed in a unique role, working as a relief pitcher with a low-90s fastball while also serving as the everyday third baseman. As a freshman, he set a San Diego State record with a 0.28 earned run average, recorded nine saves and 24 strikeouts in 32 innings, and was named a freshman First Team All-American by Baseball America and Collegiate Baseball Newspaper. He was also named the Most Valuable Player of the Mountain West Conference Championships.
As a sophomore, Schmitt batted .315/.415/.450 with five home runs and 36 runs batted in, while also posting a 3-3 record with a 3.77 ERA, eight saves, and 44 strikeouts in 43 innings, earning second-team All-Mountain West Conference honors. Following the 2019 season, he played collegiate summer baseball for the Cotuit Kettleers of the Cape Cod Baseball League, where he was named a league all-star and the league’s playoff Most Valuable Player. His junior year in 2020 was shortened by the coronavirus pandemic, but he still batted .323/.386/.452 in 16 games and tied for the national lead with six saves, earning 2020 All-Mountain West recognition.
Casey Schmitt Career
Early Career (2020-2021)
The San Francisco Giants selected Schmitt in the second round, 49th overall, of the 2020 Major League Baseball draft, signing him to a $1.15 million bonus with the plan that he would focus solely on playing third base. In 2021, he began his professional career with the San Jose Giants of Low-A West, where he batted .247/.318/.406 in 251 at bats with eight home runs and 29 runs batted in. His first full season ended early in August when a pitch fractured his left wrist, but he was recognized by Baseball America as the best infield arm and the best defensive infielder in the Giants system.
Minor League Breakthrough (2022)
In 2022, Schmitt moved through three levels of the Giants system, playing for the High-A Eugene Emeralds, the Double-A Richmond Flying Squirrels, and the Triple-A Sacramento River Cats. He batted a combined .293/.365/.489 in 468 at bats with 21 home runs and 78 runs batted in, and he expanded his defensive versatility by playing 83 games at third base and 40 games at shortstop. With Eugene, he finished seventh in the Northwest League with 58 runs and 59 runs batted in and third with 17 home runs, earning Northwest League post-season All-Star honors.
He was also named a Pacific Coast League Gold Glove Award winner and repeated as the best infield arm and best defensive infielder in the Giants system according to Baseball America. The biggest honor of his season came when he was named the 2022 Minor League Baseball Gold Glove winner as the best defensive third baseman in the minor leagues, cementing his reputation as a premium glove-first prospect. That recognition positioned him for a chance to compete for a role in the major leagues the following spring.
San Francisco Giants Era (2023-Present)
Schmitt was assigned to Triple-A Sacramento to begin the 2023 season and batted .313/.352/.410 with one home run and 22 runs batted in over 32 games. On May 9, 2023, the Giants selected him to the 40-man roster and he made his major league debut that same day, hitting his first major league home run off Patrick Corbin of the Washington Nationals. In his first three games, he joined Willie McCovey as one of only two players in franchise history with eight hits in their first three games and joined Joe DiMaggio as one of only two players with at least eight hits, four runs batted in, and four runs scored in their first three games since the RBI became an official stat in 1920. He finished his rookie year batting .206/.256/.324 with five home runs and 30 runs batted in across 90 games.
On February 20, 2024, Schmitt officially changed his uniform number from 6 to 10 after manager Bob Melvin took No. 6, and he began the 2024 season at Triple-A Sacramento before being recalled on May 10. In June 2025, he became the first player in Giants history to hit two grand slams in consecutive games, doing so against the Los Angeles Dodgers, with the first off Yoshinobu Yamamoto and the second off position player Enrique Hernández. He made 95 appearances for San Francisco during the year, batting .237/.305/.401 with career highs of 12 home runs and 40 runs batted in, and on December 2 he underwent surgery to remove a carpal boss from his left wrist.
Driving Style and Strengths
Schmitt is widely recognized for his defensive excellence, with strong footwork, soft hands, and a well-regarded throwing arm that have made him a fixture at the hot corner throughout his career. He has also shown the ability to play shortstop and second base, giving his managers flexibility when constructing the infield. On the mound in college, his low-90s fastball and control allowed him to close games, and that competitive toughness has carried over to his approach at the plate as a contact-oriented hitter with developing power.
Notable Events and Milestones
Among Schmitt’s signature accomplishments are his 2022 Minor League Baseball Gold Glove Award, his historic opening stretch with the Giants in May 2023, and his back-to-back grand slams against the Dodgers in June 2025. His first major league home run off Patrick Corbin on debut day, his franchise-tying eight hits in his first three games, and his surgery to address a long-standing wrist issue each marked important moments in his early big-league tenure.

Family Background and Racing Lineage

Personal Life
Schmitt grew up in the San Diego area and attended Eastlake High School in nearby Chula Vista before enrolling at San Diego State University. Publicly available information about his personal relationships has not been confirmed, and he has generally kept his private life out of the public spotlight while focusing on his baseball career.
2025 Season Performance
The 2025 season was a breakout year for Schmitt at the plate, as he set new career highs in both home runs and runs batted in while playing regular innings for the San Francisco Giants. He appeared in 95 games for San Francisco and batted .237/.305/.401, producing 12 home runs and 40 runs batted in, a step forward from his rookie totals the year before.
His most memorable stretch came in June 2025, when he became the first player in Giants franchise history to hit two grand slams in consecutive games, both against the rival Los Angeles Dodgers. The first grand slam came off Dodgers starter Yoshinobu Yamamoto, and the second came off position player Enrique Hernández, a dramatic sequence that highlighted his growing power and clutch hitting against high-profile opponents.
Off the field, Schmitt underwent surgery on December 2, 2025, to remove a carpal boss from his left wrist, an issue tied to the same wrist he had fractured in 2021 during his first full professional season. The procedure was designed to address a longstanding problem rather than a new injury, and the Giants expect him to be ready for full participation in 2026 spring training. With his defensive reputation intact and his offensive production trending upward, Schmitt entered the offseason positioned as a key piece of the Giants’ infield plans for the year ahead.
