He has previously played in MLB for the Washington Nationals, Chicago White Sox, Los Angeles Angels, Cleveland Guardians, and Boston Red Sox. Giolito was selected by the Nationals in the first round of the 2012 MLB draft and made his MLB debut with Washington in 2016. His fastball has been clocked as high as 100 miles per hour. In 2019 as a member of the White Sox, he earned his first MLB All-Star selection. On August 25, 2020, he threw a no-hitter against the Pittsburgh Pirates in a 4-0 victory at Guaranteed Rate Field.

Early Life and Background

Lucas Giolito was born at Providence Saint Joseph Medical Center in Burbank, California, on July 14, 1994, and grew up in Santa Monica, California. He comes from a family deeply rooted in the entertainment industry. His mother is actress Lindsay Frost, his father is actor Rick Giolito, and his maternal grandfather was actor Warren Frost. His paternal grandfather, Silvio Giolito, was a two-time Olympic fencer and multiple-time United States National Champion. His uncle Mark Frost is a novelist, television screenwriter, and producer best known as the co-creator of the television series Twin Peaks with David Lynch.

Giolito began playing tee-ball at the age of 5 and continued in the Santa Monica Little League program. He threw his first 90-mile-per-hour pitch at the age of 14, showcasing the exceptional arm strength that would define his future career. He attended Harvard-Westlake School in Studio City, Los Angeles, where he played baseball alongside future MLB pitchers Max Fried and Jack Flaherty, with Ethan Katz serving as their pitching coach.

Path to Professional Baseball

During his senior year at Harvard-Westlake School in March 2012, Giolito sprained the ulnar collateral ligament in his right elbow, which ended his high school season prematurely. Despite concerns about his elbow, he had committed to play college baseball at the University of California, Los Angeles (UCLA) for the Bruins before beginning his professional career.

Giolito was widely projected as a top selection in the 2012 MLB draft, with some analysts believing he deserved the first overall pick. However, the elbow injury caused him to fall to the 16th overall selection, where the Washington Nationals chose him. He signed with the Nationals on July 13, 2012, just thirty seconds before the deadline, receiving a $2.925 million signing bonus. Shortly after signing, it was announced that he would need Tommy John surgery to repair the damaged elbow ligament, which ended his 2012 season before it began.

Washington Nationals (2012-2016)

Following his Tommy John surgery in 2012, Giolito began his professional rehabilitation in 2013, making eight starts for the Gulf Coast Nationals of the rookie-level Gulf Coast League. He posted a 2.78 earned run average (ERA) and was promoted to the Auburn Doubledays of the Low-A New York-Penn League, where he allowed only one earned run in 16 innings pitched.

In 2014, Giolito played his first full professional season with the Hagerstown Suns of the Single-A South Atlantic League. He went 10-2 with a 2.20 ERA and 110 strikeouts compared to 28 walks over 20 starts. His dominant performance earned him recognition as the 2014 South Atlantic League Most Valuable Pitcher and Top Minor League Prospect. He also participated in the All-Star Futures Game that summer. Giolito began 2015 with the Potomac Nationals of the High-A Carolina League and earned a midseason promotion to the Harrisburg Senators of the Double-A Eastern League, where he started the 2016 season before advancing to the Syracuse Chiefs of the Triple-A International League in July 2016.

Chicago White Sox (2017-2023)

On December 7, 2016, the Nationals traded Giolito along with Reynaldo Lopez and Dane Dunning to the Chicago White Sox in exchange for Adam Eaton. Entering the 2017 season, Giolito was ranked as the 12th best prospect in all of baseball according to MLB.com. He began that season with the Charlotte Knights of the International League before earning his first MLB victory on August 27, 2017, in a 7-1 White Sox win over the Detroit Tigers. He threw seven scoreless innings, allowing only three hits and striking out four batters. Giolito finished the 2017 season with a 3-3 record and a 2.38 ERA in seven starts.

The 2018 season proved challenging for Giolito as he made 32 starts for the White Sox starting rotation, posting a 10-13 record with a 6.13 ERA. In 173 and one-third innings, he struck out 125 batters but led the American League in walks with 90 and earned runs allowed with 118. He also finished among the league leaders in hit batters, wild pitches, and home runs allowed, making 2018 a difficult developmental year.

The 2019 season marked Giolito’s breakthrough as he went on a nine-game winning streak after starting the year with a 10-1 record. He pitched his first career shutout on May 23 against the Houston Astros and was named American League Pitcher of the Month for May. On June 30, 2019, Giolito was selected to his first MLB All-Star Game as one of the American League pitchers. He pitched one scoreless inning in the exhibition game. Giolito finished the 2019 season with a 14-9 record, a 3.41 ERA, 228 strikeouts, and three complete games over 176 and two-thirds innings in 29 starts. He also finished sixth in the American League Cy Young Award voting that season.

On August 25, 2020, Giolito threw a no-hitter against the Pittsburgh Pirates at Guaranteed Rate Field, leading the White Sox to a 4-0 victory. He struck out 13 batters and threw 74 of 101 pitches for strikes. A fourth-inning walk to Erik Gonzalez was the only blemish in an otherwise dominant performance. The no-hitter was the 19th in White Sox history and the first at Guaranteed Rate Field. That season, Giolito went 4-3 with a 3.48 ERA and 97 strikeouts in 72 and one-third innings as the White Sox qualified for the playoffs. In his postseason debut against the Oakland Athletics in the Wild Card Series, he pitched seven innings, allowing two hits, one walk, one run, and striking out eight batters to earn the win in a 4-1 victory.

Giolito continued as a reliable starter for the White Sox in 2021, making 31 starts with an 11-9 record and a 3.53 ERA while striking out 201 batters in 178 and two-thirds innings. In 2022, he made 30 starts with an 11-9 record and a 4.90 ERA, striking out 177 batters in 161 and two-thirds innings. On January 13, 2023, he signed a one-year, $10.4 million contract with the White Sox, avoiding salary arbitration.

Los Angeles Angels and Cleveland Guardians (2023)

On July 26, 2023, the White Sox traded Giolito and Reynaldo Lopez to the Los Angeles Angels in exchange for minor league players Ky Bush and Edgar Quero. He made his Angels debut on July 28 against the Toronto Blue Jays, allowing three earned runs and striking out five batters in five and one-third innings. The Angels placed Giolito on waivers in late August after he posted a 6.89 ERA in six starts.

On August 31, 2023, the Cleveland Guardians claimed Giolito off waivers. He made his first start for the Guardians on September 4 and became the first pitcher since Bill Magee in 1899 to surrender eight earned runs in a game for three different MLB teams in the same season. He became a free agent following the 2023 season.

Boston Red Sox (2024-2025)

On January 3, 2024, Giolito signed a one-year contract with the Boston Red Sox that included a player option for 2025. In early March 2024, Red Sox manager Alex Cora announced that Giolito would miss the start of the season due to discomfort in his right elbow. It was later determined that Giolito required surgery and was expected to miss the entire 2024 season. An internal brace procedure was performed on March 12, 2024, involving repair to his ulnar collateral ligament. Giolito did not pitch in 2024 and exercised his $19 million option for the 2025 season.

Giolito returned to the mound in 2025, making 26 starts for the Red Sox with a 10-4 record and a 3.41 ERA. He declined his player option after the season and became a free agent.

San Diego Padres (2026-Present)

On April 22, 2026, Giolito signed a one-year major league contract with the San Diego Padres that included a mutual option for the 2027 season. He joined a talented Padres rotation as they competed for a playoff berth in the National League.

Driving Style and Strengths

Giolito features a overpowering four-seam fastball that has been clocked as high as 100 miles per hour, giving him the ability to rack up strikeouts when he commands the zone effectively.

His career-high strikeout totals demonstrate his ability to dominate lineups when he maintains consistent command of all his pitches.
