Thaiss (undisclosed) arrived at the Angels' camp Sunday, Mike DiGiovanna of the Los Angeles Times reports.
Thaiss wasn't at camp for the first several days for an undisclosed reason, but his presence with the team signals that he's cleared intake testing and will be able to partake in team activities. Thaiss is expected to serve as a reserve corner infielder for the Angels this season. It's unclear whether he'll be ready for Opening Day.
