Robles has a roster spot waiting for him when he's ready, Christopher Smith of MassLive.com reports.
Robles was late arriving to camp due to visa issues and just made his first spring appearance Monday, when he worked around a hit and a walk while fanning two over one inning. Boston manager Alex Cora said Robles might be ready for Opening Day, but the Red Sox will first evaluate the right-hander Tuesday after throwing 23 pitches (14 strikes). Given that he's uncertain for Opening Day, Robles is not seen as a candidate for Red Sox's unsettled situation at closer at this time. The 31-year-old has closing experience and could enter the mix once his arm has been built up.
