Professional career

Seattle Mariners

2006

In his first professional season in 2006 he split time between Arizona League Mariners appearing in seven games and Single-A Inland Empire 66ers appearing in one game of the California League. He posted an 0-2 record overall with a 2.25 ERA in 16 innings striking out 17 batters and starting five games. He pitched three hitless innings for Inland Empire during his brief time there.

2007

Morrow was invited to spring training in 2007. He went 0-1 with a 1.08 ERA in 6 relief appearances and made the major league club despite being considered a long-shot to make the club at the start of spring.

Morrow made his Major League debut on April 3 against the Oakland Athletics, pitching one scoreless inning.

Morrow went 3-4, with a 4.12 ERA in 60 appearances striking out 66 batters and walking 50. He held opposing hitters to a .243 batting average, including .221 against right-handed batters. He set a club rookie record with 18 holds, breaking old record of 13 set by Ed Vande Berg in 1982. Morrow had the fourth most appearances by a rookie reliever in club history with 60 and fifth most strikeouts with 66. Among American League rookie relievers Morrow ranked second in strikeouts, third in appearances and fourth in ERA.

On April 23 he earned his first major league win against the Texas Rangers, allowing one hit in career-high three and one third innings pitched. He recorded 18 and two thirds consecutive scoreless innings from April 20 to June 8. During the streak he went 2-0 while holding opposing batters to a .103 average. He also recorded another scoreless streak of 17 innings pitched over 15 outings from July 17 to August 24. Morrow held opponents scoreless in 44 of 60 outings.

2008

After missing two weeks of spring training in 2008 due to a sore shoulder, Morrow was optioned to the Mariners minor league affiliate Double-A West Tennessee on March 30. Morrow was recalled to the Seattle bullpen 17 days afterwards when Mariners starter Érik Bédard was placed on the 15-day disabled list. When Seattle's regular closer J. J. Putz became injured on June 12, Morrow took over his duties. Including a closing appearance on June 11, Morrow saved 8 games in 8 tries, before a July 10 opportunity when he gave up two solo home runs to the Oakland Athletics to acquire his first blown save. He had only given up 2 runs all year prior to that, and had 40 strikeouts in 36.2 innings pitched, and a very low ERA of 1.76 and WHIP of 0.88.

On August 5, 2008, Morrow was optioned to Triple-A to become a starting pitcher.

Morrow made his first MLB start on September 5, 2008, against the New York Yankees. Morrow went 72⁄₃ no-hit innings in his first major league start and was 4 outs away to being just the second player to throw a no hitter in their MLB starting debut only to see pinch hitter Wilson Betemit end his bid. The Mariners went on to win the game 3-1 giving Morrow his first win as a starter.

2009

On March 29, 2009 the Mariners announced that Morrow would no longer be used as a starting pitcher; instead he would move into a relief role with the organization. Morrow, who has Type 1 diabetes, acknowledged that his diabetes was a factor in the decision, saying that it was easier to balance his blood sugar in a relief position.

Morrow began the season as the closer and earned five saves through the end of April. However, he was placed on the disabled list on May 2 after he developed right biceps tendinitis. David Aardsma served as closer in his absence.

After coming off the disabled list Morrow returned to the starting rotation, making six starts before being optioned to the Triple-A Tacoma Rainiers to develop back into a more rounded starting pitcher.

On August 14 Morrow pitched a four hit shutout against the Iowa Cubs. During that game Morrow struck out two, walked one and threw 59 of 96 pitches for strikes. Morrow retired 10 straight batters early in the game.

Morrow won his fifth consecutive decision for Tacoma tossing five scoreless innings to lead the Rainiers to a 4-1 win over the Portland Beavers on August 29. Morrow was removed from the game because of stiffness in his arm.

On September 9, Morrow was called up to the Mariners. He was to start at least one game, so manager Don Wakamatsu could assess Morrow's progress. On September 30, Morrow gave up one hit and walked two hitters in 8 shutout innings against the Oakland Athletics. The Mariners won the game 7-0.

Toronto Blue Jays

On December 22, 2009 the Mariners traded Morrow to the Toronto Blue Jays for pitcher Brandon League and minor league outfielder Johermyn Chávez.

2010

Morrow's first season in Toronto was the first of his major league career as a full-time member of a starting rotation. Toronto's coaching staff altered Morrow's delivery in a similar fashion to the way Roy Halladay's delivery was altered during his first years with the Blue Jays. The switch from an over-the-top arm motion to a lower-angle arm slot was believed to have contributed to an increased command of his pitches. He was also encouraged to reduce his pitch velocity and try to induce weak contact, again much in the same way Halladay was taught during his tenure in Toronto. Despite some struggles with inconsistency during the early stages of the alterations, statistics show that his production stabilized as the season progressed and he managed to produce favorable results on a regular basis before the end of the season, including a stellar 17 strikeout, one hit performance that was a candidate for MLB.com's This Year in Baseball Performance of the Year.

On August 8, Morrow was one out away from a no-hitter against the Tampa Bay Rays when Evan Longoria hit an infield single. It would have been the first no-hitter by a Blue Jay since Dave Stieb's no-hitter on September 2, 1990. He finished the one-hitter for his first complete game while compiling 17 strikeouts, a career high for Morrow in a game and one strikeout shy of the team record 18 strikeouts set by Roger Clemens in 1998. According to the Game Score metric devised by sabremetrician Bill James, this tied for the fourth-highest rated pitching performance since 1920, with a game score of 100.

On August 29, the Blue Jays announced that after his next start, Morrow would be shut down for the season to protect his arm. He pitched more innings in 2010 (146⅓) than in any of his previous seasons. He finished the season with a 10-7 record, 4.49 ERA, and 178 strikeouts. Morrow was nominated as one of 2010's "Ten People Making a Difference in Diabetes".

2011

Morrow, who was expected to be the Jays' No. 2 starter in the pitching rotation, began the season on the 15-day disabled list with right forearm inflammation. He made his regular-season debut on April 23 against the Tampa Bay Rays, pitching 5⅓ innings, giving up 3 hits, 2 runs, 2 walks and 10 strikeouts.

For the first time since being traded, Morrow returned to the home stadium of his former team, the Seattle Mariners, to start against them on August 17. Morrow recorded the win, pitching 6 innings and striking out 12 batters.

Morrow became the first pitcher in major league history to pitch 100 innings in one season without the team recording a double play behind him. On September 23, after 173⅓ innings dating back to August 28, 2010, Desmond Jennings of the Tampa Bay Rays grounded into Morrow's first double play in 30 starts. Morrow finished the season with an 11-11 record, 4.79 ERA, and 203 strikeouts. He led the league in strikeouts over 9 innings with 10.2.

2012

On May 3, in a game against the Los Angeles Angels of Anaheim, Morrow threw a three-hit complete game shutout. The following night, teammate Henderson Álvarez also threw a complete game shutout. Morrow and Álvarez thus became the first Blue Jays starters to throw back-to-back shutouts since Jack Morris and Al Leiter did so on June 16 and 17, 1993. Morrow established a career high in complete games and shutouts (with 2 each) on May 19, throwing a three-hit shutout against the New York Mets. He improved that mark on June 6 against the Chicago White Sox, throwing a complete game two-hit shutout. His third shutout of the season gave him the league lead at the time.

Morrow experienced "stabbing pain" during the first inning of his June 11 start while pitching to Bryce Harper, the second hitter in the Washington Nationals lineup. After delivering three pitches to Harper, Morrow left the game with a strain of the left oblique muscles. No timetable was given for Morrow's return to the rotation. Morrow returned from the 60-day disabled list on August 25. In 124⅔ innings, he finished the season with a 10-7 record, 2.96 ERA, and 103 strikeouts.

2013

On February 5, 2013, manager John Gibbons named Morrow the number 2 starter for the upcoming season, behind reigning NL Cy Young Award winner R.A. Dickey. After opening the season with a 2-3 record and a 5.63 earned run average, Morrow was placed on the 15-day disabled list on June 1 with a right forearm strain. He made his first rehab start at High-A Dunedin on June 17, and pitched just 2 innings. On June 18, it was announced that Morrow had been pulled from rehabilitation after suffering an unnamed setback during his start. An MRI that day revealed only inflammation, and no structural damage in Morrow's arm.

On July 24, it was reported by Rogers Sportsnet that Morrow was diagnosed with an entrapped radial nerve in his right forearm, and will likely miss the rest of the 2013 season. Blue Jays management said the following day that they expect Morrow to pitch again in 2013, either in late September or in October's instructional league in Florida. Manager John Gibbons later said on August 22 that Morrow would remain on the disabled list for the rest of the season. In 2013, Morrow posted a record of 2-3, a 5.63 earned run average, and 41 strikeouts over just 541⁄₃ innings pitched.

2014

Morrow struggled throughout early spring training, giving up 7 earned runs through just 8 innings pitched. On March 18, manager John Gibbons confirmed that Morrow would be the team's fifth starter, citing a need to give him more time to prepare for the regular season. After struggling to open the season, including a start on April 26 where he walked 8 Red Sox batters over 22⁄₃ innings, Morrow was placed on the 15-day disabled list on May 3 with a sprained right index finger. Later that day his injury was determined to be a more severe torn tendon sheath in his right hand, and he was transferred to the 60-day DL. Morrow made his first rehab appearance on August 27 with the Dunedin Blue Jays, pitching one scoreless inning. He was activated from the 60-day DL and added to the Blue Jays active roster on September 1, 2014. On November 1, the Blue Jays declined Morrow's $10 million 2015 option, making him a free agent.

San Diego Padres

On December 16, 2014, Morrow signed a 1-year, $2.5 million contract with the San Diego Padres. He made 5 starts with the Padres in 2015, posting a 2.73 ERA and 23 strikeouts, before going on the disabled list with right shoulder inflammation in early May. He remained on the disabled list into August, when it was determined that he required season-ending surgery to correct a shoulder impingement. On December 17, Morrow signed a minor league contract with the Padres that included an invitation to spring training.

Pitching style

Morrow throws a hard fastball which sits between 90 and 96 mph but has been clocked as high as 100 mph. He has the ability to throw several off-speed pitches, including a slider (85-89 mph), curveball (81-85 mph), and change-up (81-87 mph). In September 2011, Morrow debuted a new cut fastball which comes from making a slight adjustment on his slider, with velocity hovering around 88-91 mph.

Personal life

Morrow is 6'3" tall and weighs 195 pounds. He is married. His favorite pitcher growing up was Pedro Martínez.

Morrow is a Type 1 diabetic who was diagnosed as a senior in high school. He wears an insulin pump to regulate his blood sugar levels.
