ANAHEIM -- When new A's outfielder Trayce Thompson gets back to the Bay Area at the end of next weekend, he expects a warm reception from his new roommate, he is just not sure it will be over-emotional.
Younger brother Klay will open the door, Trayce will step inside and not much figures to be said. The Thompson brothers will be under one roof again, just like when they were kids.
"I'm sure if you guys have talked to him before, he's not the biggest talker in the world," Trayce said of his NBA All-Star brother who will have started the run toward another NBA title with the Golden State Warriors by the time Sunday night rolls around. "That's how he is with us, too. He'll be excited, I'm sure, when I see him for the first time."
Trayce Thompson joined the A's before Saturday's 7-3 win over the Angels at Angel Stadium, a few days after being claimed off waivers from the Yankees. 
Thompson was waived by the Dodgers a few days before Opening Day, then claimed by the Yankees, who tried to sneak him through waivers and assign him to Triple-A. The A's had a different idea.
"I've been in this position before," Thompson said. "This game is funny and is definitely a roller-coaster of a game, especially for me the last few years, but I have been in this role before and I know what it takes."
He likely will have to deliver quickly, otherwise his stay in Oakland might not even last as long as his brother's run in the NBA playoffs. To avoid thinking about the pressure, Thompson will let his new living arrangement take him back to simpler times.
"This will be the first time I've stayed with [Klay], and my older brother, for an extended period of time since high school," Thompson said. "Klay going to basketball practice and me going to baseball. It will be interesting."
A spot on the A's also reunited Thompson with infielder Marcus Semien. The two played on three separate teams in the White Sox system when they were young prospects. If anybody knows Thompson's game, it is Semien.
"I think he's a great athlete and he's been successful in this league before," Semien said. "He just has to be confident and I think he's a confident kid. He's played pro ball for a long time. I've seen him at his best. I'm sure he will be just fine with the culture here. It's just baseball here. There is less media attention, less distractions."
Manager Bob Melvin was not putting a timetable on how long his new outfielder might be with the club.
"We'll see where it goes," Melvin said. "We'll try to sprinkle him in the outfield, give him some time there. We're down a couple of outfielders and Boog [Powell] is kind of banged up too. The timing is good for [Thompson] to be here right now."
The timing is also right so that Thompson can watch Klay's most recent playoff run up close. So how do those Warriors look, anyway?
"Well I know they are banged up a little bit, but if they get Steph [Curry] healthy, they're a heck of a team," Thompson said. "Klay is back, Draymond [Green] is good, [Kevin] Durant is back, the whole team is back. Hopefully they get Pat McCaw back. But they're the Warriors. You can't count them out. They have obviously been battled-tested. They just have to get Steph healthy and see what happens."
