Cuban infielder Yuliesky Gurriel has received his work visa and is playing in the minors in Houston's system.
Gurriel made his debut for the Gulf Coast League Astros on Saturday, going 0 for 3 with two strikeouts.
Earlier in July, Houston signed Gurriel to a $47.5 million, five-year contract. He was one of the most sought international free agents since defecting from Cuba in February.
Gurriel is primarily a third baseman but also has played second base and shortstop. He was a designated hitter Saturday.
