HOUSTON -- The Giants restored left-hander Jeremy Affeldt to their bullpen Wednesday and cleared roster room for him by placing right-hander Clay Hensley on the 15-day disabled list with a strained right groin. Affeldt used exactly one day of his three-day paternity leave and rejoined the team after his wife, Larissa, gave birth to their third son, Kolt Kristopher, on Tuesday. The need to create a vacancy for Affeldt prompted the Giants to shelve Hensley, who hurt himself while pitching. Hensley has allowed nine runs and 10 hits spanning 5 2/3 innings in his last eight games, hiking his ERA from 2.95 to 4.37. "He hasn't been as sharp with his command," Bochy said, citing a difference in Hensley's performance since he sustained his injury.
