Salazar shined in his major league debut when he made a spot start for the Indians earlier in 2013. Against the Blue Jays on July 11, he pitched six innings of two-hit ball, allowing one run while striking out seven batters.
The 23-year-old Dominican has been excellent in the minors the past three seasons. Salazar reached Triple-A Columbus for the first time in 2013 and had a 2.73 ERA 0.978 WHIP over 14 appearances. He also averaged 11.8 strikeouts per nine innings and 2.8 walks per nine innings with Columbus.
The Indians had a spot for Salazar after pushing Ubaldo Jimenez's next start back two days to Friday. Jimenez has been struggling and Cleveland hopes a couple more days of rest will help.
Salazar took to Twitter to thank his followers, saying that he first heard about the call-up from congratulations he received on the social media network before receiving a call from his manager.
