Here are Sunday’s minor moves from around MLB:
- The Nationals have signed righty Hector Ambriz, who had been with the independent Long Island Ducks, SB Nation’s Chris Cotillo tweets. Ambriz, 30, pitched briefly for the Padres last season, spending most of the year pitching respectably out of the bullpen for Triple-A El Paso, with a 3.93 ERA, 7.0 K/9 and 2.9 BB/9. He pitched 36 1/3 innings for the 2013 Astros, posting a 5.70 ERA with 6.7 K/9 and 3.5 BB/9.
- The White Sox have outrighted right-hander Javy Guerra to Triple-A Charlotte, tweets JJ Stankevitz of CSNChicago.com. Guerra was designated for assignment Wednesday when he was activated from the disabled list. The 29-year-old made just three appearances for the White Sox this season before shoulder inflammation landed him on the DL. Guerra will use his time at Charlotte to round into the form he showed in 2014 in the White Sox’s bullpen (2.91 ERA, 7.4 K/9, and 3.9 BB/9 in 46 1/3 innings over 42 games).
- Per MLBTR’s DFA Tracker., Anthony Swarzak (Indians), Reid Brignac (Marlins), and Ronald Torreyes (Astros) remain in DFA limbo.
