Owings holds Georgia's high school home run record with 69, fourth in the nation only to Drew Henson, Jeff Clement, and James Peterson.

Owings played college baseball at Georgia Tech in 2003 and 2004 before transferring to Tulane University in New Orleans.

Owings was a long shot to make the Diamondbacks' Opening Day roster in 2007, but was ultimately named the fifth starter[4] over Enrique González, Dana Eveland, Dustin Nippert, and Yusmeiro Petit.

Originally brought up to fill a starter spot while Randy Johnson recovered from back surgery, management was very impressed by his performances.

On July 26, Owings hit his first Major League home run against Byung-hyun Kim of the Florida Marlins.

[8] Later in 2007, on September 27, Owings made an emergency start in place of Brandon Webb and pitched 61⁄3 innings of shutout ball, while going 4-for-4 at the plate with three doubles and three RBI.

[9] His batting average of .333 ranked fourth best for pitchers since 1973, the beginning of the designated hitter era (in the American League).

[10] On December 5, 2007, the Arizona Republic newspaper reported that the Diamondbacks were considering playing Owings at first base during the days that he was not pitching, in an effort to get his potent bat into the lineup on a more regular basis.

[17] Reds GM Walt Jocketty stated that Owings had requested a trade "to another club that would have a better future for him".

[18] On August 26, 2010, the Reds announced that Owings had cleared waivers and had accepted an outright assignment to the Triple-A Louisville Bats.

On January 24, 2011, Owings signed a minor league contract with the Arizona Diamondbacks and he would try out at first base, along with his normal starting pitcher role.

Micah Owings was recalled from the Triple-A Reno Aces May 21, 2011, to take the roster spot opened by the release of Russell Branyan.

The eighth victory came on an outing on September 27 where Owings gave up 5 runs in the 10th, but the Diamondbacks rallied for 6 in the bottom half of the frame.

After not expecting to pitch again that season, Owings planned to play first base, left field, and designated hitter in Triple-A in Tucson.

In 213 plate appearances with Triple-A Syracuse Chiefs, Owings hit eight home runs and posted a .785 OPS.

On July 13, 2013, the Milwaukee Brewers signed Owings to a minor-league contract in which he was expected to play both the outfield and pitch.

Owings works in the Cincinnati Reds organization as a bench coach for the Billings Mustangs of the Pioneer League.
