Jason Kendall Adam Bio
Jason Kendall Adam (born August 4, 1991) is an American professional baseball pitcher for the San Diego Padres of Major League Baseball (MLB). A right-handed relief pitcher, Adam has also played in MLB for the Kansas City Royals, Toronto Blue Jays, Chicago Cubs, and Tampa Bay Rays. In 2025, Adam was named to his first All-Star game, cementing his reputation as one of the most dependable late-inning arms in the league.
Early Life and Background
Jason Kendall Adam grew up in the Overland Park, Kansas area and attended Blue Valley Northwest High School, where he pitched for the school’s baseball team. In his senior season, Adam logged more than 41 innings on the mound and posted a 2.16 earned run average. He also showed exceptional control, racking up 79 strikeouts against just seven walks, a ratio that drew the attention of professional scouts.
Coming out of high school, Adam was a highly regarded amateur prospect and committed to play college baseball at the University of Missouri. Instead, he chose to begin his professional career when the Kansas City Royals selected him in the 2010 MLB Draft. That decision launched a long minor-league journey that would eventually carry him to the major leagues.
Path to Professional Baseball
Adam signed with the Royals and forwent his college commitment, beginning his pro career in 2011 with the Single-A Kane County Cougars. He went 6-9 with a 4.23 ERA in 21 appearances that year, a steady but unspectacular start. The following season, Adam moved up to the High-A Wilmington Blue Rocks, where he logged 158 innings and posted a 3.53 ERA while winning seven games.
In 2013, Adam advanced to the Double-A Northwest Arkansas Naturals and continued to handle a heavy workload. He split 2014 between the Naturals and the Triple-A Omaha Storm Chasers, refining his slider-heavy approach. On August 11, 2014, Adam was traded to the Minnesota Twins in exchange for veteran outfielder Josh Willingham. He did not appear in a major league game in 2015 or 2016 as he worked his way back from injuries.
Jason Kendall Adam Career
Early Career (2017-2018)
After electing free agency in November 2016, Adam signed a minor-league deal with the San Diego Padres organization on July 20, 2017, and briefly pitched for the Double-A San Antonio Missions and the rookie-level Arizona League Padres. He was released on August 14 of that year, and four days later signed a minor-league contract with the Kansas City Royals. Adam finished the year with the Northwest Arkansas Naturals before getting his first big-league opportunity.
The Royals selected Adam’s contract on May 4, 2018, and he made his major league debut the following day. He appeared in 31 games for Kansas City that season, posting a 6.12 ERA across 32⅓ innings. Adam was non-tendered after the season, re-signed to a minor-league deal, and then dealt to the Toronto Blue Jays in March 2019.
Toronto Blue Jays Breakthrough (2019)
Adam opened the 2019 season with the Triple-A Buffalo Bisons and was called up to the majors on August 1. He picked up his first major league win on August 10, tossing an inning of relief in a 5-4 victory over the New York Yankees. Adam finished the year with a 2.91 ERA in 23 appearances and led all major league pitchers by allowing hard contact on just 20.0 percent of balls in play. He became a free agent in December after being non-tendered by Toronto.
Chicago Cubs Era (2020-2021)
On January 14, 2020, Adam signed a minor-league contract with the Chicago Cubs and was added to the active roster on August 16. He posted a 3.29 ERA with a 2-1 record and 21 strikeouts in 13⅔ innings that shortened season. Adam struggled early in 2021, pitching to an 8.22 ERA in nine appearances before a dislocated left ankle required surgery on May 21. He was released by the Cubs, re-signed on a minor-league deal in July, and returned to the majors in September before being non-tendered in November.
Tampa Bay Rays Era (2022-2024)
Adam signed a one-year deal with the Tampa Bay Rays on March 17, 2022, and quickly became a key piece of the bullpen. He finished the year with a 1.56 ERA in 67 appearances and eight saves, then starred in the American League Wild Card Series against the Cleveland Guardians by escaping a bases-loaded jam in the sixth inning of Game 2. In 2023, Adam made 56 appearances, posting a 2.98 ERA with 69 strikeouts and 12 saves in 54⅓ innings, and earning a $1.775 million salary through arbitration. He added 47 appearances in 2024 with a 2.49 ERA and four saves before being traded to San Diego.
San Diego Padres Era (2024-Present)
On July 28, 2024, Adam was traded to the San Diego Padres in a package that brought back prospects Dylan Lesko, Homer Bush Jr., and J.D. Gonzalez. He made an immediate impact, posting a 3-0 record and 1.01 ERA with 31 strikeouts in 26⅔ innings down the stretch. Adam carried that success into 2025, making 65 appearances with an 8-4 record, 1.93 ERA, and 70 strikeouts across 65⅓ innings, which earned him his first career All-Star selection. On September 1, 2025, he suffered a tendon rupture in his left quad while facing the Baltimore Orioles and was transferred to the 60-day injured list on September 30, ending his season ahead of the Wild Card Series against the Chicago Cubs.
Driving Style and Strengths
Adam relies on a heavy slider as his primary weapon, pairing it with a sinker that he uses to generate ground balls and weak contact. He is at his best against right-handed lineups, and his low walk rates and ability to limit hard contact have made him a trusted late-inning option. His calm demeanor on the mound and willingness to attack the strike zone have earned him the confidence of managers and catchers alike.
Notable Events and Milestones
Adam’s first major league win came in 2019 against the Yankees, and his first All-Star selection came in 2025 with the Padres. He played a key role in the 2022 American League Wild Card Series, helping keep Tampa Bay in a tight game against Cleveland. Adam also represented the United States at the 2023 World Baseball Classic, pitching four scoreless innings and striking out five, including appearances in the championship game against Japan.
