Dominguez was optioned to Triple-A Louisville on Sunday, MLB.com's Mark Sheldon reports. Dominguez has received just 20 at-bats since he was called up from Triple-A Louisville on June 11, tallying six hits (three for extra bases) and three RBI, albeit with an 8:0 K:BB ratio. The 28-year-old has good power and a bit of speed, but his K:BB ratios have been consistently terrible throughout his professional career, mostly limiting him to the Triple-A level in recent years.

Dominguez was recalled from Triple-A Louisville on Thursday. With Zack Cozart (knee) effectively ruled out for the year and Brandon Phillips banged up, the Reds went ahead and added Dominguez and Eugenio Suarez. Whereas Suarez seems like a good bet to take on a regular role at short, Dominguez may very well just fill a utility infield role in the short term after batting .208/.256/.377 in his first 49 games with Louisville this season.

The Reds optioned Dominguez to Triple-A Louisville on Monday. Dominguez had three plate appearances as a pinch-hitter after earning an Opening Day roster spot, striking out all three times.

Dominguez had his contract selected by the Reds on Sunday. Dominguez was already named to the Opening Day roster, so it was just a matter of time before this occurred. He will serve as a utility infielder for the Reds in 2015, though an injury could send him to a starting spot.

Dominguez will make the Reds' Opening Day roster, though the Reds haven't yet added him to the 40-man roster. Dominguez has just 18 major league plate appearances, but tore it up this spring, hitting .327/.333/.618. Of concern, however, is that he had 15 strikeouts in 55 at-bats, with zero walks.

Dominguez has a reasonable chance of making the Reds' Opening Day roster now that Eugenio Suarez has been optioned to Triple-A Louisville. He is currently the top backup listed at shortstop and second base, and nobody else on the current roster is really capable of playing short. He'll still need to get added to the 40-man roster, however, so his spot isn't entirely ensured.

Dominguez signed a minor league contract with the Reds on Wednesday that includes an invite to spring training.Dominguez spent most of 2014 at the Triple-A level, batting .274/.307/.460 with 21 home runs and 85 RBI with the club. However, he did see a little playing time in the majors, but recorded just one hit in 17 at-bats, though that was a home run. He will get another chance to crack a big league roster out of spring training with the Reds, but his versatility playing multiple infield and outfield positions could give him a shot with a strong showing.

Dominguez was released by the Giants on Wednesday. A .274/.307/.460 batting line, 21 homers and 85 RBI in 131 games with Triple-A Fresno last season weren't enough for Dominguez to save his spot on the Giants' 40-man roster, and he's now out of a job completely. He should latch with another club before long, but Dominguez will likely need to cut down on his strikeouts (27.1% K% with Fresno last season) before he gets another major league opportunity.

Dominguez was designated for assignment by the Giants on Thursday. Dominguez, a third-round pick in 2009, earned his first promotion to the big club last season by batting .274/.307/.460 with 21 homers and 85 RBI in 131 games with Triple-A Fresno. He did not fare well with the big club, however, going 1-for-18 in eight games, and his high-strikeout, low-walk tendencies ultimately cost him his spot on the 40-man roster. Dominguez will now be subjected to waivers.

Dominguez got the start in left field and went 1-for-2 with his first career home run in the loss to San Diego on Sunday. Dominguez got a surprise start in left field for a Giants team that is dealing with injuries to multiple starters right now. Juan Perez has been the main beneficiary of playing time, but he received a day off for rest, which opened the door for the 27-year-old rookie. In 131 games with Triple-A Fresno this year, Dominguez hit 21 homers and stole 21 bases but struggled with his plate discipline (143:22 K:BB ratio). He may see another start or two before the season ends, but he isn't a player to be relied on down the stretch.
