PHILADELPHIA -- The Giants' nonstop tinkering with their pitching staff continued Thursday as they transferred right-hander Johnny Cueto to the 60-day disabled list to facilitate right-hander Jose Valdez's arrival from Triple-A Sacramento.
Cueto likely will need most of June to recover from his sore right elbow.
Re-classifying Cueto enabled the Giants to create 40-man roster room for Valdez, who was 1-2 with a 3.71 ERA in 12 appearances at Sacramento. To vacate a spot on the 25-man active roster for Valdez, who has pitched for the Tigers, Angels and Padres, the Giants optioned right-hander Derek Law to Sacramento.
Giants manager Bruce Bochy indicated that similar moves to keep the pitching staff fresh will be forthcoming. He mentioned Sacramento right-handers Tyler Beede and Dereck Rodriguez as others who the Giants have considered summoning.
San Francisco also reinstated left-hander Josh Osich (hip) from the disabled list and optioned him to Sacramento.
