Sardinas was recalled from Triple-A Tacoma on Wednesday.
Sardinas received a promotion while the Mariners sent Chris Taylor down to Triple-A. The 23-year-old was ineffective in his first stint with the Mariners, hitting just .154/.185/.269 in 12 games to start the season. However, he has been scorching hot in Triple-A thus far, hitting .406/.457/.438 with four RBI and two stolen bases and will look to build on that success in Seattle.
