SUNDAY: The Pirates have reportedly re-signed Sadler, so he'll remain in the organization. He isn't on the 40-man roster, but he also hadn't been since being outrighted, so it's not clear why the Bucs handled this move this way, but that's more of a curiosity than anything. Upshot: Sadler will be in the Pirates organization in 2016, but it's very likely he won't pitch.
SATURDAY: The Pirates have released Casey Sadler, Matt Eddy of Baseball America tweets. (Thanks to Pirates Prospects for the link.) Sadler had forearm trouble this season and didn't pitch after June 21, and he had Tommy John surgery in the fall. The Pirates then outrighted him in November. That they would release him isn't a surprise -- he likely wasn't going to pitch in 2016, and his upside was limited even when he was healthy. Sadler was solid minor league depth, but he wasn't someone a good team would want taking regular turns in the majors.
Sadler's release marks the end of his Pirates career, and he'll face an uphill battle to get back to the majors with any team. If he does mount a comeback bid, it likely won't be until 2017. In the meantime, though, he does get to keep his memories of playing in the big leagues, chief among them an excellent start against the Brewers last April. That was Sadler's seventh and, thus far, last appearance in the majors.
