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.
The Mariners announced Friday that Mitch Haniger has been diagnosed with a Grade 2 oblique strain.
That's what was initially suspected and means the outfielder is expected to miss 3-4 weeks of action. The hard-hitting rookie was sizzling at the plate to start the season, hitting .338/.442/.600 with four homers and 16 RBI.
Padres pitching prospect Anderson Espinoza has again been shut down with right elbow soreness.
The top prospect was shut down for a couple weeks earlier this month due to forearm tightness. The good news is an MRI didn't reveal anything serious. "This is a young man who throws very, very hard," Padres farm director Sam Geaney said. "He hasn’t to this point had any extreme workloads, but I think when you generate as much velocity as he does, these kinds of things happen. Often times it can take six to eight weeks for something like this to resolve itself and get back to normal."
Junior Guerra (calf) has resumed throwing bullpen sessions.
He's slated to throw a couple live batting practice sessions beginning early next week and then be cleared to begin a rehab assignment if all goes well. Guerra is working his way back from a strained right calf that he suffered in his first start of the season. He hopes to rejoin the Brewers' rotation before the end of May.
Zach Britton (forearm) will be activated from the disabled list either Sunday or Tuesday.
Britton will begin a rehab assignment at Double-A Bowie on Friday. Assuming everything goes off without a hitch, he'll likely be activated Sunday after the one appearance. However, if the Orioles determine that he needs another one, they'll delay his activation until Tuesday. Brad Brach has been filling in at closer.
