6:34pm: Southpaw Wade LeBlanc is also on irrevocable waivers, Rob Biertempfel of the Pittsburgh Tribune-Review tweets. LeBlanc is earning just $750K this year and can be controlled next year via arbitration or a $1.25MM club option (with a $50K buyout).

The 33-year-old lefty has thrown 61 1/3 innings on the season, working to a 4.99 ERA with 7.0 K/9 and 2.3 BB/9. He has surrendered ten long balls in that span. As has been the case for most of his career, LeBlanc has posted reverse platoon splits, with lefty batters hammering him and righties managing only a .234/.288/.418 slash.

6:14pm: The Pirates have placed right-handed reliever Juan Nicasio on outright waivers, according to a report from Bill Brink of the Pittsburgh Post-Gazette. Unlike revocable trade waivers, outright waivers cannot be rescinded — meaning that any team can simply claim Nicasio at this point.
