Irvin (hip) threw a bullpen session Saturday and remains on track to make his next scheduled start Tuesday against the Tigers, the Associated Press reports.
Irvin appeared to get through the session without any setbacks, keeping the left-hander on pace to not miss a start with the hip discomfort that led to his early exit from his Tuesday outing versus Seattle. The 27-year-old will be looking to bounce back from a rough stretch if he does take the hill against Detroit, as he's pitched to a 5.79 ERA and 2.07 WHIP across 14 innings over his last three starts.
