After sweeping the Seattle Mariners in a series that was moved to the Bay Area, due to the smoke in Seattle, the San Francisco Giants began their road series of the season.

Luckily, the road trip that the Giants are on is 15.6 miles away from Oracle Park across the Bay Bridge then down Interstate 880 to the Oakland Coliseum.

It’s nice that everybody got to sleep in their own beds last night,” said Giants manager Gabe Kapler. “Considering that these are road games and we did just get to play two road games in our ballpark, there have been a lot of challenges throughout this season and so those are two things that we can point to as positives and pluses.”

Matt Olson hit a three-run home run, helping the Oakland A’s to a 6-0 victory over the Giants, as the A’s clinched their sixth playoff spot in the past nine seasons.

Newly acquired Jake Lamb put the A’s on the board in the bottom of the first inning, as he hit a run-scoring single that gave the A’s a lead that they would never give up.

Chris Bassitt went 6.2 innings, striking out seven, as he won his third straight start for the American League Western Division Leading A’s.

Both Tommy La Stella and Marcus Semien each added run-scoring singles for the A’s, who were coming off a day off on Thursday and the Giants played a two-game series.

Logan Webb went just 3.1 innings, as his record fell to 2-4 on the season and his streak for winless starts is now at five. Since defeating the Arizona Diamondbacks at Oracle Park on August 21, Webb is now 0-2.

Not a good performance from our offense. I think all of our players will tell you that,” Kapler said. “We have to play better baseball than that down the stretch if we’re going to get into the postseason.”

The Giants could manage just three hits on the evening, as their 6,7,8 batters of Brandon Crawford, Darin Ruf and Joey Bart went a combined 3-for-11, while the other six batters in the lineup went a combined 0-for-19 with five walks and 11 strikeouts against four A’s pitchers.

NOTES: Mike Yastrzemski missed the game after he left Thursdays game with tightness in his right calf. Yastrzemski underwent an MRI on Friday that revealed a mild calf strain and is listed as day-to-day and will not be placed on the injured list.

Yaz is important enough to this club where we really don’t know how long it’s going to be, whether it’s one, two, three days or more and we want to ensure that we have (options) there,” Kapler said.

Prior to the game, the Giants sent Rico Garcia and Wandy Peralta to the alternate site, while both Shaun Anderson and Andrew Suarez were recalled from the alternate site. Peralta threw a career-high three innings in Thursdays 6-4 victory over the Seattle Mariners.

This was just the fourth time this season that the Giants have been shutout and just the fifth time that they picked up five hits or fewer in the same game.

All four shutouts have been by teams in the State of California, as the Los Angeles Dodgers shut them out twice, the San Diego Padres on Sunday and the A’s tonight.

UP NEXT: Kevin Gausman will take the mound after missing his start on Sunday after the Colorado Rockies due to elbow soreness, while the A’s will send Jesus Luzardo to the mound, as they look to clinch their first AL Western Division Championship since 2013, as their magic number is 2.
