Daniel David Norris (born April 25, 1993) is an American professional baseball pitcher who is a free agent.

He has previously played in Major League Baseball (MLB) for the Toronto Blue Jays, Detroit Tigers, Milwaukee Brewers, Chicago Cubs, and Cleveland Guardians.

[4] In 2013, Norris split time with the Single-A Lansing Lugnuts and High-A Dunedin Blue Jays, and finished the season with a 2–7 record, but made a major improvement with his ERA, which dropped to 3.97.

[7] On June 15, he was called up to the Double-A New Hampshire Fisher Cats after posting a 6–0 record, 1.22 ERA, and 1.025 WHIP in 13 starts with Dunedin.

[10] With New Hampshire, Norris had a 3–1 win–loss record, 4.54 ERA, and struck out 49 in 352⁄3 innings before he was promoted to the Triple-A Buffalo Bisons on August 7.

[11] Making his Triple-A debut pitching in the first game of a double-header on August 10, Norris earned the win, pitching six innings against the Durham Bulls and gave up only two hits while striking out 10, including Wil Myers, on a rehabilitation assignment for the Tampa Bay Rays.

[15] While speculation circulated that the Blue Jays intended to move Norris to the bullpen following his third Triple-A start, they instead announced on August 22 that he would continue in a starter's role.

In total for 2014, Norris pitched 62⁄3 innings with the Blue Jays, and post a 5.40 ERA, four strikeouts, and a 1.50 WHIP.

Norris had arthroscopic surgery on October 7, 2014, to remove bone spurs and loose bodies from his left (pitching) elbow.

[26] On July 30, 2015, Norris was traded to the Detroit Tigers along with Matt Boyd and Jairo Labourt in exchange for David Price.

Following the home run to Davis, Norris retired the next 12 batters in a row, earning the win in a 6–1 Tigers victory.

The Tigers eventually lost the bid for a combined no-hitter with one out in the ninth inning when Neftali Feliz, the fifth pitcher used, surrendered a triple to Tyler Saladino.

[32] Norris finished the 2015 season (combined stats between Toronto and Detroit) with a 3–2 record in 13 starts, while compiling a 3.75 ERA and 45 strikeouts in 60 innings.

On March 24, 2016, the Tigers announced that Norris would start the 2016 season on the disabled list, due to a lower back issue suffered during spring training.

[37] Norris made 13 starts for the Tigers in 2016, finishing the season with a 4–2 record and a 3.38 ERA, while striking out 71 batters in 69+1⁄3 innings.

Although he logged the most innings of his young career (101+2⁄3), Norris took a step backward in 2017, posting a 5–8 record and a 5.31 ERA while striking out 86 batters.

Norris dealt with hip and quadriceps issues during the season, and admitted he dug a "deeper hole" by trying to come back too soon from a DL stint.

[40] Norris returned from the disabled list on September 1 but came out of the game in the fifth inning with a left leg injury right after giving up a 2-run home run which earned him the loss.

[42] Norris ended the season with a 3–13 record despite setting career highs in games (32), starts (29), innings (144+1⁄3) and strikeouts (125).

On July 30, 2021, Norris was traded to the Milwaukee Brewers in exchange for minor league prospect Reese Olson.

[55] He tossed two scoreless innings out of the bullpen in his only appearance before he was designated for assignment following the promotion of Gavin Williams on June 21.

[58] After clearing waivers, Norris elected free agency in lieu of accepting another outright assignment to Columbus.

Prior to the 2015 season, Tony LaCava, Toronto's assistant general manager said of Norris, "He takes care of himself as well as anybody we've got.

He was diagnosed the previous April, and with a doctor's consent, he continued playing and delayed treatment until the end of the season.

During the 2015 season, he acquired professional photographer Ben Moon's Canon EF 85mm portrait lens, and the two became friends.
