Daniel Mengden (foot) to throw live batting practice on Saturday.
The 24-year-old hurler continues to progress in his recovery from a broken foot. He's expected to be ready to rejoin the Athletics' rotation in late May.
Sean Manaea (shoulder) is likely to have his next start pushed back.
It doesn't appear as though Manaea will be heading to the disabled list due to his shoulder tightness, but it doesn't look as though he'll be ready to take the ball on Tuesday. In that case, Sonny Gray would start on Tuesday with Kendall Graveman pitching on Wednesday for the A's.
Buster Posey is not in the Giants starting lineup for Friday's showdown against the Padres.
It appears to be just a routine day of rest for the hard-hitting backstop. Nick Hundley is starting behind the plate while Mike Morse draws a start at first base and is hitting cleanup for the Giants on Friday.
Brandon Phillips (groin) remains out of the Braves starting lineup on Friday.
Phillips was forced to leave Wednesday's game due to a strained left groin but is adamant that he won't require a trip to the disabled list. Braves' skipper Brian Snitker said he hopes to have Phillips back in there on Saturday.
The Mariners announced Friday that Felix Hernandez has been diagnosed with bursitis in his shoulder and is expected to miss 3-4 weeks.
The veteran right-hander has forced to leave his start on Tuesday due to fatigue in his shoulder. Chase De Jong is expected to hold down his spot in the rotation for the next couple of weeks but doesn't make for an appealing fantasy option.
