PHOENIX — The Arizona Diamondbacks placed left-handed pitcher Eduardo Rodríguez on the injured list Friday because of shoulder inflammation.
The 32-year-old has struggled this season with a 1-3 record and a 7.05 ERA over nine starts. He has given up 21 earned runs over his past 16 innings, spanning four mostly ineffective starts.
Right-hander Ryne Nelson is the most likely candidate to take Rodriguez’s spot in the rotation. He has a 5.13 ERA over 10 outings, including one start.
The D-backs also added right-handers Christian Montes De Oca and Scott McGough to the big league roster and sent struggling left-hander Joe Mantiply to Triple-A Reno.
