Lucas Giolito was a first-round pick in the 2012 amateur draft.
Giolito had a 9-1, 1.00 record with 78 strikeouts in 70 1/3 innings his junior year of high school. He also spent some time at the Urban Youth Academy. He appeared in the Aflac All-American Baseball Classic in 2012. He did not pitch much that year as he sprained his ulnar collateral nerve in his right elbow. Timed at 100 mph in high school, he was still intriguing enough despite the injury to be picked by the Washington Nationals 16th overall in the 2012 draft. Surprisingly, he was not even the first pitcher taken from his school, as Max Fried went at #7. He signed just before the deadline for a $2.925 million bonus and made his pro debut with the GCL Nationals on August 14th, allowing one run in two innings but reinjured his elbow before he could appear again and underwent Tommy John surgery. He split 2013 between the GCL Nationals and Auburn Doubledays and went 2-1 with a 1.96 ERA in 11 starts. He had 39 Ks in 36 2/3 innings.
In 2014, he had his first full season as a professional, making 20 starts for the Hagerstown Suns of the South Atlantic League, during which he went 10-2, 2.20. He struck out 110 in 98 innings, walking only 28. He played in the 2014 Futures Game, but was shut down in mid-August, as the Nationals wanted to limit his innings coming off the surgery, as they had infamously done with ace Stephen Strasburg two seasons earlier. Mlb.com ranked him as the top righthanded pitching prospect in baseball coming into the 2015 season. He split that year between the Potomac Nationals of the Carolina League and the Harrisburg Senators of the AA Eastern League. He was a combined 7-7, 3.15 in 21 games, with 131 strikeouts in 117 innings. He returned to the Futures Game that season.
The Nationals announced on June 27, 2016 that Giolito would make his major league debut the next day starting against the New York Mets. They had just placed Strasburg on the disabled list and needed another starter. He had begun the year at Harrisburg, where he was 5-3, 3.17 in 14 starts at the time of his call-up. His debut came on a rainy night that cut his outing to only four innings, but he impressed during that time, allowing no runs on only one hit and a pair of walks. Washington won the game, 5-0, but he had to settle for a no-decision. He made only 6 appearances for the Nats, including 4 starts ending up 0-1 with a 6.75 ERA. In addition to his time at Harrisburg, he made 7 starts for the AAA Syracuse Chiefs, going 1-2, 2.17 for a combined minor league line of 6-5, 2.97. On December 8th, he was one of three young pitchers traded by Washington to the Chicago White Sox in return for CF Adam Eaton, the others being Reynaldo Lopez and Dane Dunning.
Giolito only made 7 starts for the White Sox in 2017, going 3-3, 2.38 as he continued his apprenticeship in the minors. He was with the AAA Charlotte Knights for most of that season, going 6-10, 4.48 in 24 starts. In 2018, he spent a first full season in the majors with the White Sox, but he found the going rough, even though he won in double figures. He finished with an ERA of 6.13 and 90 walks allowed in 173 1/3 innings. He led the American League in both walks and earned runs allowed (118). His record was 10-13, and on the positive side, he gave up less than a hit per inning (166 in 173 1/3) and struck out 125. He got off on the right foot in 2019 as in his first start of the year on March 31st, he took a no-hitter into the 7th inning before Alex Gordon of the Kansas City Royals singled with one out. He gave up a couple more hits and 2 runners came in to score before he was taken out, but he still ended up with credit for a 6-3 win. It was a sign of things to come as he took a big step forward. He was the American League Pitcher of the Month in May when he went 5-0, 1.74 in 6 starts. As a reward for his remarkable transformation into a top-notch starter, he was named to the All-Star team.
