Adam Rosales hit a go-ahead homer off James Shields in the eighth in Oakland's 2-1 defeat of Kansas City on Friday.
The A's had been going with Eric Sogard against righties and Rosales against lefties, but Rosales drew the assignment against Shields tonight and came through with the big blast. As poorly as Sogard has hit, the A's will probably go with Rosales regularly for now.
Jarrod Parker pitched seven innings of one-run ball in a no-decision against the Royals on Friday.
The A's didn't go ahead until the bottom of the eighth, so Parker was denied the win after his best performance so far this season. He struck out five and walked two tonight. After opening up 0-4 with an 8.10 ERA, he's 2-1 with a 4.07 ERA his last four times out.
Yoenis Cespedes went 0-for-4 on Friday to drop under the Mendoza Line at .198.
Cespedes has just four hits and one RBI in his last 10 games. His slump hasn't included many strikeouts -- in fact, he's gone six straight games without one -- but he might be fighting some lingering weakness from his illness earlier this week.
Chris Young (quad) had some cramping in his leg after Thursday's rehab game, but hopes to be activated from the disabled list on Saturday.
Young was originally expected to be activated following Thursday's rehab game, but it appears that the leg cramping set him back a day. It's not expected to be a major setback, so look for him to return to the A's lineup at some point over the weekend.
John Jaso (leg) indicated Friday that his right leg is still sore, making him unlikely to be available for Friday night's game against the Royals.
Jaso was hit in the leg by a pitch during Wednesday's game and said that it still hurt running to his mailbox. Derek Norris is will continue to handle the catching duties while Jaso is sidelined.
Chris Young (quad) is not expected to be activated from the disabled list Friday.
Young, currently sidelined with a quad injury, went 1-for-1 with two walks and a stolen base Thursday in a rehab game with Triple-A Sacramento. There was speculation that he would be activated Friday, but the A's apparently think that he needs at least one more day.
Brett Anderson was diagnosed with a navicular stress fracture of his right foot and will be shut down for four weeks.
Rough news for Anderson, who just can't seem to stay healthy. The 25-year-old southpaw is set to be reevaluated after four weeks, so his actual return to the Athletics likely won't be until around the early part of July. Dan Straily is filling his spot in the rotation for now, but the A's could turn to Sonny Gray if he continues to struggle.
