“He's close enough to where we all have our fingers crossed for him,” Melvin said. “This whole thing is so sad. It puts things into perspective when you're out on a baseball field playing baseball.”

Angels: C Max Stassi was out a day after leaving in the second inning at San Francisco when hit in the right knee by a foul ball. X-rays were negative. He suffered a bruise and a strain. "I would say it's going to be at least two, three weeks at the minimum," manager Joe Maddon said. The Angels were already short-handed at catcher after Jason Castro exited Wednesday’s game following a five-game absence because of neck stiffness. Anthony Bemboom started behind the plate. ... DH Shohei Ohtani got a break to work on his swing and will play again Saturday. “It'll be very important for us to get him right,” Maddon said.

Athletics: LHP A.J. Puk was scheduled to throw another bullpen at the team's San Jose alternate site, then is likely to take two days off before throwing to hitters. Melvin figures he will need to face live hitting a few times before returning to the A's as a potential long reliever to fill a void after the A's lost Burch Smith last weekend to a strained forearm. “If we can get him up to three innings that would take care of that, even multiple innings. Our starters are going a little bit longer now,” Melvin said of Puk. “In theory you don't need four, five, six, something like that, so even two innings would be considered probably that role and my guess is we'll get him up to at least two innings before he's here.”

OUCH

T. Bear, a giant stuffed orange bear in the left-field seats, was OK and smiling with his head wrapped in tape a day after taking a foul ball from the bat of Arizona's Ketel Marte. The bear, unavailable for interviews for 48 hours after a concussion per the team, cradled the souvenir ball.
