The Phillies said welcome to Justin Bour (above) yesterday and buh-bye to Zach Eflin.

Bour is the Phils’ newest player, having been traded for from Miami on Friday, and Eflin, one of the team’s most effective hurlers, was optioned to Triple-A Lehigh Valley.

With a doubleheader scheduled against the Mets next week, manager Gabe Kapler said it’s likely Eflin won’t miss his next start. Teams are permitted to carry 26 players on doubleheader days, so Eflin could be recalled to start one of the games.
