Anderson, who underwent an arthroscopic debridement of his right elbow in November, is in the race for one of the last remaining bullpen spots on the big league roster, MLB.com's Jordan Bastian reports.
Siegrist (shoulder) threw his first bullpen session of spring Wednesday, Glenn Sattell of MLB.com reports. "It was good," said Siegrist, who threw about 25 pitches. "Everything was fine. [I threw] all fastballs and changeups. No pain, nothing like that. Now it's just all about building back up to get ready to throw in games. I feel good so far."
Upton feels his struggles in recent years have made him "mentally stronger" and well-prepared to hang on to the starting job in left field, which is bursting with competition breathing down his neck, Mike Nabors of MLB.com reports.
