Diamondbacks promote Tomas from Triple-A

San Diego, CA (SportsNetwork.com) - The Arizona Diamondbacks have recalled heralded Cuban outfielder Yasmany Tomas from Triple-A Reno prior to Wednesday's game against the San Diego Padres.

Tomas, signed to a six-year, $68.5 million contract by Arizona over the winter, is not in the starting lineup for Wednesday's series finale.

The 24-year-old slugger had been slated to begin the season as the Diamondbacks' regular third baseman, but struggled defensively with the position switch during spring training and lost the job to Jake Lamb.

Arizona subsequently optioned Tomas to Reno, where he has gone 4-for-21 with a home run and three RBI over five games while playing exclusively in right field.

Tomas was on Cuba's World Baseball Classic in 2013 and hit .375 with a pair of homers and five RBI in the tournament. The power-hitting prospect played five seasons in Cuba's Serie Nacional prior to defecting from his native land in November.
