Manager Brad Ausmus indicated Rondon's (shoulder) live bullpen session Thursday went without issue, Anthony Fenech of the Detroit Free Press reports. Rondon's expected to require at least one more bullpen session, but his timetable for returning to the Tigers' bullpen remains up in the air. With Joe Nathan (elbow) out for the season, he could be one of the top options for saves should Joakim Soria falter or suffer an injury.
