Phillips was placed on the 10-day injured list with a right quadriceps strain Friday, Fabian Ardaya of The Athletic reports.
Phillips made his Dodgers debut Thursday and allowed a run on three hits and no walks while striking out one in 2.1 innings to earn the win over the Mets. However, he apparently suffered a quad injury that will prompt a trip to the injured list. It's not yet clear when the right-hander will be able to return.
