It appears the Dodgers medical staff is growing, with the reported addition of longtime Rays head athletic trainer Ron Porterfield, per Marc Topkin of the Tampa Bay Times:
Porterfield will serve as medical director with the Dodgers, working under former Rays baseball operations chief Andrew Friedman, to provide leadership, oversight and direction to their staff while based at the team's Arizona facility.
...
Porterfield said he decided to make the move for several reasons: That he was moving into a newly created position to provide leadership, that it would create opportunity for promotion among the Rays staff and that it would allow him to spend more time with his family on a daily basis, and to be closer to extended family, including his parents, in New Mexico.
