Yasmani Grandal, who played 56 games with the Tucson Padres in 2012, has been suspended 50 games by Major League Baseball for testosterone use.

The suspension was announced by MLB on Wednesday. He will first be eligible to play May 28.

"I apologize to the fans, my teammates and to the San Diego Padres," Grandal said in a statement. "I was disappointed to learn of my positive test, and under the joint drug program I am responsible for what I put into my body. I must accept responsibility for my actions and serve my suspension."

Grandal, a catcher, was a star in Tucson, hitting .335 with 24 extra-base hits (18 doubles) and 35 RBIs. He was called up to San Diego in the middle of the season and thrived with the big-league club.

He hit .297 in San Diego in 60 games with eight home runs and 36 RBIs.

Also on Wednesday, San Diego traded outfielder Blake Tekotte to the White Sox for right-hander Brandon Kloess. Tekotte, a 25-year-old outfielder, played in 89 games for Tucson.

He left to spend more time with his family and last season coached Regis Jesuit High School in Aurora, Colo., to a 20-6 record and the 5A semifinals of the state championship.
