Starting pitcher Tyler Glasnow began his professional career in 2012.
The hurler was taken by the Pittsburgh Pirates as the first pick in the fifth round of the 2011 amateur draft, the same round as outfielder Mookie Betts. The scout was Rick Allen. Between the GCL Pirates and State College Spikes in 2012, the hurler went 0-3 with a 1.88 ERA in 12 games (11 starts), striking out 44 batters in 38 1/3 innings. With the West Virginia Power in 2013, Glasnow went 9-3 with a 2.18 ERA in 24 starts, allowing only 54 hits in 111 1/3 innings, while K-ing a South Atlantic League-leading 164 batsmen. He earned numerous accolades that year: He was a MiLB.com Organization All-Star, was a SAL Mid- and Post-Season SAL All-Star and was a Topps Class-A All-Star.
Entering 2014, he was named the 27th-best prospect in the game by MLB.com, the #42 prospect by Baseball Prospectus and #46 by Baseball America. Baseball America also named him the #3 prospect in the Pirates system. He pitched for the Bradenton Marauders that year and went 12-5 with a 1.74 ERA in 23 starts, allowing only 74 hits with 157 strikeouts in 124 1/3 innings. He was named the Florida State League Most Valuable Player, the MiLB.com Staff Choice for Best Starting Pitcher, a Baseball America Minor League All-Star, a MiLB.com Organization All-Star and a FSL Post-Season All-Star. MLB.com ranked him the 12th-best prospect entering 2015, while Baseball America ranked him #16 and Baseball Prospectus #21. Baseball America also ranked him #1 in the Pirates system.
Glasnow made his debut with the Pirates on July 7, 2016, starting against the St. Louis Cardinals. He had been 7-2, 1.78 with the AAA Indianapolis Indians before his call-up. He pitched into the 6th inning in his first game, but charged with a 5-1 loss after giving up 4 runs in 5 1/3 innings; he also recorded his first career hit. He was the fourth top pitching prospect to make his debut with the Bucs in a span of a few weeks, following Jameson Taillon, Chad Kuhl and Steven Brault. He went 0-2, 4.24 in 7 games, then in 2017 got a more extensive look, with 13 starts in 15 appearances. However, he went just 2-7, 7.69 and spent the bulk of the year back in the minors. In 2018, he was moved to the bullpen and had made 34 appearances, having gone 1-2, 4.34 in 56 innings when on July 31st he was traded to the Tampa Bay Rays along with OF Austin Meadows and a player to be named later in return for P Chris Archer. He made 11 starts with Tampa, going 1-5, 4.20.
Glasnow started off the 2019 season with a bang as he was 5-0, 1.75 in 6 starts in March and April, earning him the title of American League Pitcher of the Month. In 36 innings, he gave up just 27 hits and struck out 38 opponents. However, on May 10th, he had to leave a start against the New York Yankees in which he suffered his first loss of the season in the 6th inning due to forearm tightness and underwent an MRI. He was immediately placed on the injured list and was expected to miss 4 to 6 weeks. The lay-off was longer, as he only returned on September 8th. He was only used as an opener pitching two or three innings in first three starts after his return, but on September 27th, his first win since May 3rd, 6-2 over the Toronto Blue Jays, was the one that clinched a wild card spot for the Rays in the postseason. He finished the season at 6-1, 1.78 in 12 starts. In the postseason, however, he lost both of his starts against the Houston Astros in the Division Series, giving up a total of 6 runs in 7 innings.
He made his first appearance of the 2020 season on July 27th and showed he still possessed some of the nastiest stuff in the majors as he struck out 9 Atlanta Braves batters in 4 innings in a game in which the Rays set a team record with 19 strikeouts in 9 innings. He went 5-1, 4.08 in 11 starts during the abbreviated season as the Rays put up the best record in the American League. He was then a mainstay of the postseason rotation as the Rays made it to the World Series for the second time in franchise history before losing to the Los Angeles Dodgers. He made 6 postseason starts, winning twice in the first two rounds, but being charged with three losses in the ALCS and World Series combined as his ERA went up with each round played. He also had issues with his pitch counts, as he used too many pitches to put batters away, and also walked too many, as witnessed by his 9 walks in 9 1/3 innings (against 15 strikeouts) in the World Series.
With the departure of Blake Snell and Charlie Morton from the Rays after the 2020 season, he became the team's new ace by default, and stepped into the role with aplomb over the first two and a half months of the season. After 14 starts on June 15th, he was 5-2, 2.66, and had struck out 123 batters in 88 innings, while dealing with his control issues as he had issued just 27 walks. However, he was placed on the injured list on that day with a UCL tear and flexor strain, a type of injury that would likely require a long absence from the mound. He blamed Major League Baseball's new guidelines on using foreign substances on the ball, saying that by cracking down on a practice that had gone on forever, MLB had placed pitchers at a disadvantage and a higher risk of injury because the baseballs were too slick.
