Lucas Giolito

Early life

Giolito was born at Providence Saint Joseph Medical Center in Burbank, California, on July 14, 1994. He grew up in Santa Monica, California. Giolito began playing tee-ball at the age of 5, and he played Little League Baseball at Santa Monica Little League. He threw his very first 90 mph pitch at the age of 14.

Amateur career

Giolito attended Harvard-Westlake School in Studio City, Los Angeles, California. He was part of a Harvard-Westlake baseball team that included Max Fried and Jack Flaherty, with Ethan Katz as their pitching coach. In March 2012, his senior year, Giolito sprained the ulnar collateral ligament in his right elbow, sidelining him for the rest of his high school season. Giolito had committed to attend the University of California, Los Angeles (UCLA) and play for the UCLA Bruins baseball team. Although some thought he was good enough to be selected with the first overall choice of the 2012 MLB draft, concerns about his elbow caused him to fall to the 16th overall selection, where he was picked by the Washington Nationals.

Professional career

Minor leagues

Giolito signed with the Nationals on July 13, 2012—thirty seconds before the deadline—to a minor league contract with a $2.925 million signing bonus. By the end of the month, the team had scheduled Tommy John surgery to repair his injured elbow ligament.

By the following summer, he made eight starts for the Gulf Coast Nationals of the rookie-level Gulf Coast League in 2013 and posted a 2.78 earned run average (ERA). He was promoted to the Auburn Doubledays of the Class A-Short Season New York–Penn League, and allowed one earned run in the 16 innings he pitched.

Giolito began the 2015 season with the Potomac Nationals of the Class A-Advanced Carolina League, and received a midseason promotion to the Harrisburg Senators of the Class AA Eastern League. The Nationals assigned Giolito to Harrisburg to start the 2016 season. He received a promotion to the Syracuse Chiefs of the Class AAA International League in July.

Washington Nationals

On June 28, 2016, the Nationals added Giolito to their active roster and he made his major league debut that night against the New York Mets. In his debut, he pitched four shutout innings, allowing one hit and two walks, while getting one strikeout.

Chicago White Sox

On December 7, 2016, the Nationals traded Giolito, Reynaldo López, and Dane Dunning to the Chicago White Sox for Adam Eaton. Entering the 2017 season, Giolito was considered the 12th best prospect in all of baseball, according to MLB.com. Giolito began the 2017 season with the Charlotte Knights of the International League. On August 27, 2017, Giolito earned his first MLB victory in a 7–1 White Sox win over the Detroit Tigers. Giolito threw seven scoreless innings yielding only three hits and striking out four Tigers. Giolito finished the season going 3–3 with a 2.38 ERA in 7 starts.

The following season, in 2018, he was part of the starting rotation, making 32 starts for the White Sox, going 10–13 with a 6.13 ERA. In innings, he struck out 125 but led the American League in walks (90) and earned runs (118), and was 3rd in the league in hit by pitch (15), 4th in wild pitches (13), and 9th in home runs allowed (27). In 2018 he had the highest rate of bases on balls per 9 innings pitched in the majors (4.67), and had the highest WHIP among major league pitchers (1.48). He also had the worst left on base percentage of all qualifying major league pitchers, stranding only 63.5% of base runners.

In 2019, Giolito's third season and second in the White Sox starting rotation, he greatly improved from the previous year 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. He was also rewarded AL pitcher of the month for the month of May. On June 30, 2019, Giolito was named as one of the American League pitchers for the 2019 MLB All-Star Game, his first All-Star selection. He pitched one scoreless inning in a 4–3 victory for the American League. On September 16, 2019, the White Sox shut down Giolito for the rest of the season due to a mild lat strain in his pitching arm. Giolito finished the season with a 14–9 record, a 3.41 ERA, 228 strikeouts and three complete games over innings in 29 starts. He also finished 6th in the AL Cy Young Award voting.

On August 25, 2020, Giolito no-hit the Pittsburgh Pirates 4–0 at Guaranteed Rate Field. He struck out 13 batters and threw 74 of 101 pitches for strikes; a fourth-inning walk to Erik González was the only blemish in an otherwise perfect game. The no-hitter was the 19th in White Sox history, the most recent having been Philip Humber's perfect game on April 21, 2012, and the most recent by a White Sox pitcher at Guaranteed Rate Field having been Mark Buehrle's perfect game on July 23, 2009. That season, Giolito went 4–3 in 12 starts with an ERA of 3.48, and struck out 97 in innings as the White Sox made the playoffs that season. Giolito made his postseason debut against the Oakland Athletics in game 1 of the Wild Card Series. He pitched 7 innings giving up 2 hits, 1 walk, 1 run, and struck out 8. He even retired the first 18 batters he faced in that game. He picked up the win as the White Sox beat the Athletics with a final score of 4–1 but the White Sox went on to lose the Series to the Athletics.

In 2021, Giolito made 31 starts with a record of 11–9 and an ERA of 3.53. He pitched in 178.2 innings and struck out 201 batters. He had the lowest ground ball percentage of all major league pitchers, at 33.2%. In 2022, Giolito had an 11–9 record in 30 starts pitching to an ERA of 4.90 in 161.2 innings giving up 171 hits and 92 runs while he struck out 177 batters.

On January 13, 2023, Giolito signed a one-year, $10.4 million contract with the White Sox, avoiding salary arbitration.

Los Angeles Angels

On July 26, 2023, Giolito and Reynaldo López were traded 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. In 5⅓ innings, he allowed three earned runs and struck out five. Giolito was placed on waivers by the Angels on August 29, after posting a 6.89 ERA in 6 starts.

Cleveland Guardians

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

Boston Red Sox

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

Giolito made 26 starts for the Red Sox in 2025, with a 10–4 record and a 3.41 ERA. He declined his option after the season and became a free agent.

Personal life

Giolito is the son of actress Lindsay Frost and actor Rick Giolito. His maternal grandfather, Warren Frost, was an actor, while his paternal grandfather, Silvio Giolito, was a two time Olympic fencer and multiple time US National Champion. Lucas’ brother Casey is an actor, while his uncle, Mark Frost, is a novelist, television screenwriter, and producer best known as the co-creator of Twin Peaks with David Lynch.
