Aaron Blair

On February 12, 2020, Blair signed a minor league deal with the Arizona Diamondbacks.

Both MLB.com and Baseball America ranked Blair the Diamondbacks' third best prospect prior to the start of the 2015 season. He started the year back in Mobile and made 13 starts, finishing with a record of 6–3 and an ERA of 2.70 over ​83  ⁄3 innings before he was promoted to the AAA Reno Aces in June, where he continued his successful 2015 campaign. Blair ended his Reno stint with a record of 7–2 and an ERA of 3.16 in the hitting-friendly Pacific Coast League. He was also named the Diamondbacks 2015 Organizational Pitcher of the Year.

On December 9, 2015, the Diamondbacks traded Blair, along with Dansby Swanson and Ender Inciarte, to the Atlanta Braves for Shelby Miller and Gabe Speier. MLB.com ranked Blair the Braves' fourth-best prospect at the start of the 2016 season. He was invited to spring training that year as a non-roster invitee. Blair began the season with the Gwinnett Braves of the Class AAA International League, and was promoted to the major leagues on April 23, making his major league debut the following day. He made 11 starts for the team and pitched to a 7.99 ERA before being optioned to Gwinnett on June 25. Blair did not collect a win in his first stint with the Braves, and he became the first Braves pitcher to take five career-opening losses since Don Collins in 1977. While in the minors, Blair injured his knee and only started nine games, pitching to a 2–4 record and a 5.98 ERA. On August 27, Blair was recalled to face the San Francisco Giants the next day. He finished four innings while yielding three home runs and took the loss. Due to this rocky performance as well as his struggles throughout the season at the major league and minor league levels, the Braves chose to remove Blair from the rotation so he could focus on improving his pitching mechanics. He started against the New York Mets on September 19, and earned his first major league victory. In 2016 in AAA, he was 5–4 with a 4.65 ERA, and in the majors he was 2–7 with a 7.59 ERA (with 14 home runs in 70 innings). He once gave up 9 runs in one inning against the Pirates at PNC Park on May 3rd 2016. In January Blair was called up for the first time during the 2017 season on April 20. In 2017 in AAA, he was 7–9 with a 5.02 ERA, and in the majors he was 0–1 with a 15.00 ERA. Blair was released on May 31, 2018, six weeks after having surgery to repair a torn muscle in his pitching shoulder.

In March 2015, Blair became engaged to Caitlyn Morrone, whom he met in college. They married in January 2017 in Las Vegas.

Blair started the 2014 campaign in South Bend but was promoted to High A Advanced Visalia Rawhide after six starts in South Bend. In his debut for Visala, Blair went seven innings, allowing one run on three hits, walking two and striking out nine. Blair would make 12 more starts for Visalia before being promoted, this time to the Southern League with the AA Mobile BayBears. Blair dominated in his first two Southern League starts, pitching a combined ​13  ⁄3 innings, allowing 1 run and 8 hits while striking out 16 and walking 1. Those performances also earned him the Southern League's Pitcher of the Week award. Blair finished the 2014 season with Mobile with a 4–1 record in 8 starts, covering ​46  ⁄3 innings with a 1.94 ERA to go along with 46 strikeouts. The season totals were a 9–5 record over 27 starts and ​154  ⁄3 innings. He struck out 171 hitters while walking 51. He was also named the Arizona Diamondbacks 2014 Minor League Pitcher of the Year.

A native of Las Vegas, Nevada, Blair threw a no-hitter in his sophomore year at Spring Valley High School. He was 7–0 his junior year and became a Nevada 1st Team All-State player his senior year while leading all Nevada 4A pitchers with 91 strikeouts in 64 innings. He had 9 complete games out of 10 starts. He added a .449 average with 7 home runs and 43 RBIs his senior year.

As a junior, Blair was added to the Golden Spikes Award watch list. Blair was named a 1st Team Conference USA pitcher. Included in his season was an 8 inning, 2 hit, 11 strikeout and no run game against the 19th ranked Houston Cougars in a 4–0 win to earn Blair Louisville Slugger National Pitcher of the Week. He finished his Marshall career with 200 strikeouts in 202 innings. Blair then became the highest drafted player in Marshall University baseball history when the Arizona Diamondbacks selected him in the 1st round with the 36th pick.

The Arizona Diamondbacks selected Blair with the 36th pick in the 2013 Major League Baseball draft. Blair signed with the Diamondbacks for a $1.435 million signing bonus and was assigned to the Hillsboro Hops of the Class A-Short Season Northwest League. He was promoted in August to the South Bend Silver Hawks of the Midwest League, where he won two playoff games.
