According to Sports Hochi, Kenta Maeda (Hiroshima) could toss a bullpen session on Sunday. The timetable for his return (tightness in his right side) will be set based on how the session goes. For now, Maeda is aiming for a return on June 15 (vs Nippon Ham at Sapporo Dome).
Nikkan Sports figures Maeda might not toss a bullpen session until the 11th.
Kazuki Yoshimi (Chunichi) started his rehab at Nagoya Stadium today. He is not allowed to do a lot of sweating right now and had to keep his workouts light. The Dragons are hoping he will be able to start throwing before the end of the year. That could put him on track for a return some time during the first half of the 2014 season.
Yoshimi had surgery on his right elbow (Tommy John surgery and an elbow cleaning) on the 4th and was discharged from the hospital on the 7th.
