What happened: The Dodgers recalled RHP Seth Halvorsen and added LHP Charlie Barnes to the roster. RHP Kyle Hurt was optioned, while RHP Jonathan Hernández was designated for assignment.
Why it matters: The moves bring one right-hander and one left-hander onto the roster while sending two right-handers out. Los Angeles' scheduled game remains 0-0 before first pitch.
By the numbers: Four pitchers were involved: two added to the roster, one optioned and one designated for assignment.
What to watch: Halvorsen and Barnes' availability for the scheduled game bears watching.
