Following the trade of Bryan Morris to the Miami Marlins, the Pittsburgh Pirates have promoted Casey Sadler to take his place on the major league roster. Sadler was pulled from his last start while he was in the bullpen warming up on Friday, so there may have been an indication at that time that a deal was going to be made.
Sadler pitched twice for the Pirates earlier this month out of the bullpen. He threw a total of four scoreless innings. In the minors with Indianapolis, he had a 2.60 ERA and 1.05 WHIP in 50.2 innings over eight starts. Sadler is an extreme ground ball pitcher, posting a 1.57 GO/AO ratio, which is in line with his career average over five seasons.
