Mat Latos (elbow) will throw two more bullpen sessions and a simulated game before beginning a rehab assignment. Latos got through a bullpen session Sunday with no issues. Manager Bryan Price doesn't want to put a timetable on the right-hander, but Latos is trending towards a late May/early June return. "I try to stay with the day to day plan. We didn't anticipate the flexor mass strain," Price said on Tuesday. We always leave it open to be able to adjust it."
