ST. PETERSBURG, Fla. -- The Tampa Bay Rays extended Major League Baseball's best start in 20 years behind Jeffrey Springs' seven innings of three-hit ball and Randy Arozarena's four RBIs, routing the Oakland Athletics 11-0 on Saturday for an 8-0 record.

Tampa Bay is the first big league team to open 8-0 since the 2003 Kansas City Royals won their first nine games. The Rays have outscored opponents 64-18 and are the first team to win its first eight games by four or more runs since the 1884 St. Louis Maroons of the Union Association did it in their first 13.

No team had won eight straight games by that margin at any point in a season since the 1939 Yankees did it 10 times in a row.

Isaac Paredes and Brandon Lowe had three RBIs each for the Rays.

"When you're winning games like this, a lot of things got to be going well," Tampa Bay manager Kevin Cash said. "So, I think we're all pretty impressed with every facet out there."

Springs (2-0), coming off six no-hit innings in his season debut against Detroit, gave up a leadoff single in the first to Esteury Ruiz. He struck out seven, raising his total to 19 in 13 innings.

"Early on, kind of fought mechanics," Springs said. "It was a grind. Overall, I felt alright, not great, but it helps a lot when my offense is doing what they're doing."

Shintaro Fujinami (0-2) allowed 5 runs, 3 hits and 4 walks and hit a batter over 4⅓ innings in his second major league start. The right-hander didn't allow a hit until Wander Franco's infield single with one out in the fourth.

"I started off pretty well in the first three innings," Fujinami said through a translator. "But the fourth inning I walked a guy, and from there it kind of went down."

Fujinami, who signed as free agent in January after pitching 10 years for Hanshin of Japan's Central League, allowed eight runs over 2⅓ innings in a 13-1 loss to the Los Angeles Angels in his big league debut April 1. His next start could be at home against the Mets' Kodai Senga.

Oakland, which had just three hits, has lost six of eight and is batting .209.

Tampa Bay scored three times in the fifth to go up 5-0 on 3 hit batters, 2 walks and a single. Arozarena ended Fujinami's day on a two-run single, and Paredes picked up an RBI when hit by a pitch from Sam Moll.

Arozarena had a two-run homer in the ninth off Carlos Pérez, usually a catcher.

Manuel Margot had a solo homer and Lowe added a three-run drive in the sixth off Domingo Acevedo.

Before the game, Tampa Bay placed center fielder Jose Siri on the 10-day injured list with a right hamstring strain. To fill the vacant roster spot, Tampa Bay recalled infielder/outfielder Vidal Brujan from its Triple-A club in Durham, North Carolina.

Siri, 27, made a running catch in the eighth inning of Friday's 9-5 home victory over the Athletics, crashing into the wall after tracking down a drive from Seth Brown.
