Chicago Cubs
Mitre was the Chicago Cubs' 7th-round selection in the 2001 Major League Baseball Draft out of San Diego City College. He was the second player out of the 2001 draft to make it to the majors with the Cubs, the first being Mark Prior. His first stop through the minors was the Boise Hawks in the Short Season Northwest League, where he pitched alongside Dontrelle Willis. In 2002, he played for the Lansing Lugnuts in the Class-A Midwest League, pitching to a 2.83 ERA in 168.2 innings.

He started the 2003 season in Double-A with the West Tennessee Diamond Jaxx, compiling a 6–7 record with a 3.79 ERA in 18 starts. Mitre led the team in innings pitched (109.1) and strikeouts (98). He was promoted to the majors on July 22 in order to start in place of the injured Prior. He allowed eight runs on 10 hits in just 3.2 innings that day and was optioned back to the minors. He made two more appearances that year for the Cubs, including a spot start on the last day of the season.

In 2004, Mitre started out the season on the Opening Day roster, filling in for the injured Mark Prior. He pitched to a 6.51 ERA through nine starts before being sent down to the Triple-A Iowa Cubs after Prior came back from injury. On August 13, 2004, Mitre pitched a complete game shutout against the Albuquerque Isotopes. He allowed a double and a walk in the first inning of the game, then sat down 23 straight batters, striking out nine. For his effort, Mitre was named the Pacific Coast League's Player of the Week. He returned to the majors in September and pitched out of the bullpen, finishing the season with a 2–4 record and 6.62 ERA in 12 games.

Mitre began the 2005 season in Triple-A. Mitre returned to the majors on May 24 to make a spot start when Kerry Wood was placed on the disabled list. He had two strong starts during his stint in the rotation. On June 8, Mitre out-pitched Roy Halladay in a 2–0 win over the Toronto Blue Jays, allowing two hits and a walk, while striking out six in seven innings. On June 14, 2005, he threw a five-hit complete game shutout in a 14–0 victory over the Florida Marlins and Josh Beckett. However, he was removed from the rotation after pitching to a 5.19 ERA in seven starts. Mitre pitched another 17 innings out of the bullpen for the Cubs that season, allowing 11 runs on 20 hits.

Florida Marlins
On December 7, 2005, Mitre and minor league pitchers Ricky Nolasco and Renyel Pinto were traded to the Florida Marlins for Juan Pierre. He started the 2006 season in the Marlins rotation, pitching to a 4.89 ERA in seven starts. On May 12, he threw just three pitches before leaving the game with shoulder discomfort. Mitre was placed on the 15-day disabled list with shoulder inflammation. He was later moved to the 60-day DL, and stayed there through August. After returning to pitch out of the bullpen, he experienced more inflammation eight games later and was shut down once again.

He started the 2007 season in the Marlins rotation, setting career bests in games played (27), starts (27), innings (149), and strikeouts (80). From May 20 to June 15, Mitre did not allow an earned run over 24.2 consecutive innings. He missed time with a blister in April and a sore hamstring in June.

Mitre started the 2008 season on the disabled list with a forearm strain. He initially attempted to rehab the injury, but ultimately underwent Tommy John ligament replacement surgery on July 15 and was expected to miss 12–18 months. The Marlins decided to release him at the end of the season.

New York Yankees
On November 3, Mitre signed a one-year minor league contract with the New York Yankees with an option for 2010. Mitre was suspended for the first 50 games of the 2009 season after testing positive for androstenedione in August 2008. Mitre said the androstenedione came from a contaminated legal supplement purchased from GNC, but took full responsibility for his actions. He served his suspension while still on the disabled list from last year's Tommy John surgery. Mitre pitched to a 2.40 ERA in seven starts for the Scranton/Wilkes-Barre Yankees in Triple-A before he was called up to start against the Baltimore Orioles on July 21. In total, he had a 6.79 ERA across 12 appearances (nine starts) that season. The Yankees declined their option on him after the season.

In January 2010, the Yankees re-signed him to a deal that avoided arbitration. He hit the disabled list with an oblique strain on June 5 and didn't return until July 24 when he started in place of the injured Andy Pettitte. That day, he allowed five runs on seven hits in 4.1 innings against the Kansas City Royals and was relieved by Dustin Moseley, who pitched 4.2 scoreless innings. For the next turn in the rotation, the Yankees used Moseley as a starter and Mitre was moved to the bullpen. He recorded his first career save on August 19, pitching the last three innings of a 11–5 win over the Detroit Tigers. Mitre pitched well out of the bullpen, compiling a 2.55 ERA in 24.2 innings, and was added to the Yankees postseason roster. His only playing time came during the American League Championship Series against the Texas Rangers, when he made three appearances in mop-up duty. He allowed home runs to Josh Hamilton and Nelson Cruz in the 9th inning of Game 4.
