Improving McCarthy remains in serious condition

SEATTLE -- Prior to Friday's game in Seattle, A's trainer Nick Paparesta said hospitalized pitcher Brandon McCarthy is progressing well and stable, but is still in serious condition.

"By no stretch of the imagination are we out of the woods, but everything is going great. He's showing great progress," Paparesta said.

McCarthy was struck in the right side of the head by a line drive during Wednesday's game against the Angels. Paparesta said it was determined after McCarthy left the field that he needed to go to the hospital for a CT Scan. He underwent surgery Wednesday night to relieve pressure on his brain caused by a skull fracture.

Paparesta said McCarthy was able to sit up in bed, and was up and around three times. He also sat in a chair and ate solid foods and drank fluids, all without complications. McCarthy is able to recognize visitors and talk, although pain is limiting how much he speaks.

"The biggest issue we deal with after these type of injuries and this type of procedure, is, from what the physicians explained to us, was that Days 2 and 3 are going to be the hardest days. Obviously, we're coming up on Day 3 tomorrow. So the evening time there is a possibility of having a recurring or the increase of swelling coming back again, and if that were the case, they would need to do some different measures and techniques to try to get that swelling, to keep it down."

As far as what can be expected as McCarthy recovers, Paparesta said it is best to take it in steps.

"First and foremost, we need to look at his life and making sure he stays alive. This is serious stuff and we want him to live," Paparesta said. "I think the next phase that we would look at is him being able to go through and have normal gross motor mechanics and skill set, where he can go through his normal active life and live normally. The third thing would be maybe we put a little bit of time to look into his fine motor skills and see where he is at that point in time."

McCarthy's injury leaves void in A's clubhouse

SEATTLE -- As the A's continue their season without pitcher Brandon McCarthy, who is hospitalized after being struck with a line drive to the right side of his head on Wednesday, they'll have to do it in tough circumstances.

"We definitely have some heavy hearts here," manager Bob Melvin said. "I don't think there is a guy on this team that isn't close to Mac."

"I think with Mac's situation, we try not to put too much into the small things that are going on in life," pitcher Jarrod Parker said. "Obviously, we know that there's bigger picture and life is life. It's not just baseball, it's everything. We know that there's life beyond baseball. I think a situation like this is really kind of going to teach us about that there's more to it and not put too much into the small things."

In terms of baseball, it will be difficult to replace what McCarthy gave to the team. He was one of the lone veterans on the pitching staff and a clubhouse leader.

"He's been our leader," Parker said. "Mac's a guy that's taught me, Tommy [Milone], Brett [Anderson] ... a lot of us about how to be a professional. The way he carries himself and the stuff he does off the field in the weight room, in the training room. He's been huge for us to kind of teach us how to prepare as starting pitchers in this league."

A's put No. 2 prospect Straily into rotation

SEATTLE -- The A's recalled rookie Dan Straily from Triple-A Sacramento on Friday to fill the open rotation spot of injured starter Brandon McCarthy's. Manager Bob Melvin said Straily, who was scheduled to start for Sacramento on Friday, will get the nod on Tuesday.

It is the second time this season the A's second-ranked prospect has been with the big league club. Straily was 1-0 with a 3.18 ERA in three starts in August during his first-career callup.

In 25 games with Sacramento and Double-A Midland, Straily is 9-7 with a 2.78 ERA and a Minor League best 190 strikeouts.

"I think he's been through all the firsts and knows what it's all about here," Melvin said. "Again, we're not afraid to throw some young pitchers out there. We got a lot of young starters in our rotation right now and he will just add to that mix."

Worth noting

• The A's entered Friday with a Major League-leading 75 home runs since the All-Star break, but saw their streak of 11 consecutive games with a homer end on Wednesday.

• The A's begin a tough stretch on Friday that sees them playing 17 of their next 20 games on the road. Five of the six teams during that span are contending for a playoff spot.
