"It doesn't really count for anything," Astros manager A.J. Hinch said. "They don't really give us credit for anything until the end of the season, but it's obviously nice to win that many games that quickly. We're pretty even-keeled around here. We don't talk a lot about getting to 40 wins, getting to 50 wins. We're going to continue to press forward and try to win as many as we can."
Houston's offense pounced on A's starter Jesse Hahn, scoring 10 runs in the first two innings. Behind two three-run homers, Houston scored eight in the second alone. It's the third time that the Astros have scored eight or more runs in an inning this season. Hahn was pulled after the second, giving up a career-high nine earned runs on six hits and three walks.
Josh Reddick added a solo shot to right in the sixth, his first homer against the A's since being traded by them last season. He finished the day a single shy of the cycle, going 3-for-4.
"You always want to do well against your former team," Reddick said. "I enjoy beating them, regardless, whether I go 0-for-4 or I go 4-for-4. So it is fun."
Rookies drove in five of the nine A's runs, with recent callup Matt Olson providing an RBI groundout in the fifth and an RBI double in a six-run eighth. Chad Pinder and Jaycob Brugman each collected RBI hits in the sixth, while Bruce Maxwell added an RBI double in the eighth.
"It was good to see these youngsters battle back, too," A's manager Bob Melvin said. "Guys [were] putting together some really good at-bats at the end of the game."
MOMENTS THAT MATTERED Fresh off the bench: After initially getting the day off, Jake Marisnick was called into action when leadoff batter George Springer was hit on the left hand by a pitch and had to exit in the first. In his first at-bat an inning later, Marisnick took Hahn deep to left-center, hitting a Statcast-projected 400-foot shot. The homer was the first three runs of the eight-run inning for the Astros. It also gave Marisnick his 10th dinger of the season, setting a personal best.
"It feels good doing all that work and then get the results," Marisnick said. "I'm excited about it, excited to kind of keep working on it and keep going."
QUOTABLE "Those are hard to come by. Four-game series in general are really tough because you see so many people over and over and over again. When you get hot like this, it's fun to be on this end. We've had a few four-game series this year, and to come out with four wins in Oakland, it's a good feeling." -- Hinch, on his team's four-game sweep
"For me, my game is coming inside on righties, throwing my sinker in on righties. I kind of babied it in there after that. I started spiking a lot, yanking stuff, and it just wasn't good." -- Hahn, on his hit-by-pitch of Springer and how it affected him
SOUND SMART WITH YOUR FRIENDS The Astros are just the 19th team in the last 50 years to win 50 of its first 74 games to begin a season, and just the 42nd club to accomplish the feat in the last century.
SPRINGER EXITS The contest got off to an ominous start for the Astros, as Springer got hit by Hahn's fifth pitch of the game. Springer exited with a left hand contusion, as X-rays came back negative. He is considered day to day. More >
