The Oakland Athletics claimed first baseman Nate Freiman off waivers from the Houston Astros on Saturday, MLB.com reports.
In order to clear a spot on the roster, Oakland placed relief pitcher Fernando Rodriguez on the 60-day disabled list. Rodriguez is likely done for the season and may need Tommy John surgery.
Freiman is a Rule 5 draft pick, so the A's will have to keep him on the roster all season or offer him back to the Padres.
