DENVER -- The Rockies acquired Minor League right-handed pitcher Armando Galarraga, who came within a blown call of a perfect game with the Tigers in 2010, from the Reds' organization for right-hander Parker Frazier on Monday, the Rockies tweeted.

Galarraga, 31, has pitched for the Rangers (2007), Tigers (2008-10), D-backs ('11) and Astros ('12), and is a combined 26-34 with a 4.78 ERA in 100 games, including 91 starts. He has not appeared in the Majors this season, and was 6-6 with a 2.98 ERA, with 62 strikeouts against 34 walks, at Triple-A Louisville. Galarraga will be sent to Triple-A Colorado Springs.

Galarraga is best known for the events of June 2, 2010, when he had retired all 26 Indians he faced until first-base umpire Jim Joyce ruled incorrectly that Jason Donald had reached safely on a ground ball. Galarraga retired the next hitter and had a one-hit, 99-pitch shutout. A distraught Joyce apologized after the game.

The two, with author Daniel Paisner, wrote a book, "Nobody's Perfect: Two Men, One Call, and a Game for Baseball History." Because of the business arrangement, Joyce no longer works games that Galarraga pitches.

Last season with the Astros, Galarraga went 3-2 with a 3.97 ERA in 10 starts.

Frazier, an eighth-round Rockies pick in 2007 out of Bishop Kelley High School in Tulsa, Okla., was 0-1 with a 10.67 ERA in nine games, including three starts, at Triple-A Colorado Springs, and 1-1 with a 2.67 ERA in 16 games, including two starts, at Double-A Tulsa. The 24-year-old was impressive as a starter at Tulsa last year (5-14, 3.88 ERA, 93 strikeouts against 26 walks in 167 innings pitched).
