3. Amateur Career
Stroman's amateur career saw him develop into a promising baseball talent through his high school and collegiate experiences, leading to his entry into professional baseball.

Stroman attended Patchogue-Medford High School in Medford, New York. During his high school years, he developed a notable rivalry with his friend and future New York Mets teammate, Steven Matz, who pitched for the nearby Ward Melville High School. Despite their rivalry, Matz and Stroman were teammates on the elite travel team, the Paveco Storm, for several years throughout junior high and high school. They were also roommates during the Area Code Games and faced each other multiple times in high school, including a particularly significant game on April 16, 2009, which attracted over 50 scouts from every MLB team.

There, he played college baseball for the Duke Blue Devils. During his collegiate career, Stroman compiled a record of 15 wins and 13 losses in 48 appearances. He set a Duke record for career strikeouts, achieving 290 strikeouts over 222 innings pitched.

In 2010 and 2011, he played collegiate summer baseball for the Orleans Firebirds of the Cape Cod Baseball League (CCBL), where he maintained a remarkable record of zero earned runs over 34 innings across his career with Orleans. He was recognized as a league all-star in 2010 and was inducted into the CCBL Hall of Fame class of 2022.

Stroman first entered the MLB draft in 2009, when he was selected by the Washington Nationals in the 18th round, 532nd overall. However, he chose not to sign with the Nationals, opting instead to attend Duke University. After his collegiate career, Stroman was again eligible for the draft. In the 2012 Major League Baseball draft, he was drafted by the Toronto Blue Jays as the 22nd overall pick in the first round. This selection made him the first player from Duke University ever to be chosen in the first round of the MLB draft. Analysts at the time considered him the most major league-ready player available in the 2012 draft.
4. Professional Career
Marcus Stroman's professional career began in the minor leagues before he made his mark with multiple Major League Baseball teams, including the Toronto Blue Jays, New York Mets, Chicago Cubs, and New York Yankees.

On July 2, 2013, he recorded 13 strikeouts over 6.67 innings in a game against the New Britain Rock Cats. His strong performance led to him being ranked as the number three prospect in the Blue Jays organization on July 26, 2013, and the 55th overall prospect in Major League Baseball ahead of the 2014 season.
In 2014, Stroman was invited to the Blue Jays' major league spring training camp. He was later assigned to the Triple-A Buffalo Bisons, where he served as their Opening Day starting pitcher. On May 3, 2014, Stroman was called up to the Major Leagues due to an injury to Brandon Morrow, at which point he was considered the organization's number two prospect.
4.2. Toronto Blue Jays

On October 6, 2014, Stroman announced he would change his uniform number from 54 to 6 in honor of his grandmother. During 2015 spring training, he suffered a torn anterior cruciate ligament (ACL) in his left knee, requiring surgery performed by Dr. James Andrews. He was placed on the 60-day disabled list on April 5. During his rehabilitation, Stroman returned to Duke University to complete his degree in sociology with a minor in Markets and Management Studies.
He began a rehab assignment on August 5, throwing off a mound for the first time since his injury on August 11. He pitched simulated games on August 24 (40 pitches) and August 28 (51 pitches). His Class-A debut with the Lansing Lugnuts on September 2 saw him pitch 4.67 innings with no hits, one walk, and seven strikeouts. His second and final rehab start was on September 7 with the Buffalo Bisons.

He was activated from the disabled list on September 11 and pitched five innings for a win in a rain-delayed game. He made three more starts, finishing the 2015 regular season with a 4-0 record, a 1.67 ERA, and 18 strikeouts in 27 innings pitched.

He further improved his single-game strikeout record on August 1, fanning 13 Houston Astros batters in a no-decision. Stroman concluded the 2016 regular season with a 9-10 record, a 4.37 ERA, and 166 strikeouts over a career-high 204 innings pitched. He led all major league pitchers with the highest ground ball percentage (60.1%) and the lowest fly ball percentage (20.4%).
On October 3, Stroman was announced as the starter for the 2016 American League Wild Card Game against the Baltimore Orioles. He pitched six full innings, giving up just two earned runs and striking out six, as the Blue Jays won 5-2 in extra innings to advance. Although scheduled to start Game 4 of the ALDS, the Blue Jays swept the Rangers. In the American League Championship Series against the Cleveland Indians, Stroman made one start, pitching 5.33 innings and yielding four earned runs in Game 3.
On February 14, 2017, Stroman won his salary arbitration case, securing a 3.40 M USD salary for the 2017 season. On April 25, in a 6-5 win over the St. Louis Cardinals, he recorded his first career hit, a double to left field. This was the first ever pinch hit by a Blue Jays pitcher and the first extra-base pinch hit by an American League pitcher since Gary Peters in 1971. On May 18, 2017, Stroman hit an opposite-field home run off Julio Teherán in the Blue Jays' 9-0 victory over the Atlanta Braves, becoming only the second Blue Jays pitcher to hit a home run (after Mark Hendrickson in 2003). His home run, following Luke Maile's solo shot, marked the first time batterymates hit back-to-back home runs since 1970. He was also the first pitcher listed 5 in or shorter to hit a major league home run since Tom Phoebus in 1968.
Stroman faced minor injuries in 2017, including a blister on his right middle finger on July 3 against the New York Yankees and being hit on the right elbow by a line drive on September 2 against the Baltimore Orioles, but neither injury caused him to miss a start. He finished the 2017 season with 13 wins, 164 strikeouts, and a 3.09 ERA in 201 innings. By reaching the 200-inning mark, he became the seventh Blue Jays pitcher in 20 years to have consecutive 200-inning seasons. For the second consecutive year, he had the highest ground ball percentage among major league pitchers (62.1%) and the lowest fly ball percentage (19.7%). On October 28, Stroman was named a finalist for the American League pitcher's Rawlings Gold Glove Award, which he subsequently won on November 7. The Toronto chapter of the Baseball Writers' Association of America unanimously voted him the Blue Jays' Pitcher of the Year for 2017.
4.2.3. 2018-2019 Seasons
On February 15, 2018, Marcus Stroman announced he had lost his salary arbitration case and would earn 6.50 M USD for the season, rather than his requested 6.90 M USD. He struggled at the start of the 2018 season, recording an 0-5 record with a 7.71 ERA before being placed on the 10-day disabled list on May 11 due to right shoulder fatigue. On June 13, he made a rehab start with the Dunedin Blue Jays (High-A), pitching 4.33 innings, allowing two runs on one hit, walking four, and striking out three. Stroman returned to Toronto's rotation on June 23, delivering five shutout innings against the Los Angeles Angels. Later in the season, blister issues in his pitching hand forced him to exit starts on August 7 and 17 against the Boston Red Sox and New York Yankees, respectively. He returned on September 3 to start against the Tampa Bay Rays, but blisters again forced him out of the game. This marked the end of his 2018 season, which he finished with a 4-9 record and a 5.54 ERA in 19 starts.
On March 13, 2019, Blue Jays manager Charlie Montoyo named Stroman the Opening Day starter. On March 28, he pitched seven innings of two-hit, shutout baseball against the Detroit Tigers, though the Blue Jays lost 0-2. Despite a 5-9 record in the first half of the season, Stroman maintained a 3.18 ERA and recorded 81 strikeouts, leading to his first career selection to the 2019 MLB All-Star Game on June 30. However, with the Blue Jays struggling and out of postseason contention, Stroman became a trade candidate.

During that offseason, he hired Nikki Huffman as his personal trainer, who had previously served as the head trainer for the Toronto Blue Jays. Stroman first met Huffman in 2015 at Duke University, where she played a crucial role in his ahead-of-schedule recovery from a torn ACL.
Stroman missed the beginning of the 2020 season due to a torn left calf muscle. On August 10, 2020, before he could return from the injury, he announced his decision to opt out of the remainder of the season due to concerns related to the COVID-19 pandemic.

In the 2021 season, Stroman returned to the mound and became a consistent presence in the Mets' starting rotation. He led the team's starters with 10 wins, 158 strikeouts, and 179 innings pitched. After the 2021 season, he became a free agent.

During the first half of the 2023 season, Stroman was a standout performer, making 19 starts with a record of 9 wins and 6 losses, and an impressive 2.96 ERA. His strong performance earned him a selection to the 2023 MLB All-Star Game, though he ultimately chose not to play in the game to rest. In August, the Cubs placed Stroman on the injured list due to inflammation in his right hip. By mid-August, he was diagnosed with a rib cage cartilage fracture.

In his first season with the Yankees, Stroman made 29 starts and one relief appearance, pitching 154.67 innings with a 4.31 ERA and 113 strikeouts. However, his performance declined towards the end of the season, with a 5.70 ERA since the start of June. As a result, Stroman was initially left off the Yankees' 26-man roster for the ALDS.
