Once Galvis returned to the Phils, I often heard the radio guys mention how well-liked he is, and that he's a positive presence in the clubhouse. He's lost a step defensively and is now probably just good rather than exceptional, and his offense has never been very good. But he can competently cover 2B, SS, and 3B, is a clubhouse positive, and doesn't cost too much. He knows the team and they know him. For more or less the same $, I doubt the Phils can do better than Galvis in the backup IF role.
He might end up starting a number of games (as did Miller and Torreyes this season) and these backup players always get overexposed in that situation, but I think that's just life when your starters aren't starting.
