The Oakland Athletics routed the Texas Rangers 12-5 to secure the American League West title for the first time in six years.
The New York Yankees were also celebrating on Wednesday night as they claimed their 13th American League East crown in 17 years with a 14-2 victory over the Boston Red Sox.
The win also gave New York (95-67) the best record in the American League and home-field advantage throughout the post-season.
The Yankees are due to face the winners of today’s wild-card contest between Baltimore and Texas in the Amercian League Division Series, which starts on Sunday.
Oakland stood 13 games behind the Rangers on June 30, but the Athletics have gone an MLB-best 57-26 since then. That included their three-game season-closing sweep of the Rangers to clinch the 15th American League West crown in team history.
“We knew this is a beast of a team we would have to beat, and to be able to beat them three games in a row and win the division on top of it, really it’s a magical type thing,” A’s manager Bob Melvin said.
Coco Crisp drove in two runs and scored twice, while Brandon Moss added three RBIs and a run scored for the A’s.
A’s pitcher Evan Scribner earned the win after throwing three scoreless innings in relief of starter A.J. Griffin. Griffin allowed five runs on seven hits in just 2-2/3 innings. Four of the five runs he allowed were earned.
Slugger David Murphy knocked in two runs and Adrian Beltre drove in one run for the Rangers, who will continue their quest for a third-straight World Series appearance when they play in a wild-card game today.
Baltimore finished second in the American League East after losing 4-1 to Tampa on Wednesday.
“You never know,” outfielder Josh Hamilton said. “This could be a blessing in disguise.”
Hamilton dropped a fly ball in the outfield for a two-run error that put Oakland ahead 7-5 in a six-run fourth inning.
Pitcher Derek Holland suffered the loss after giving up three runs on three hits and two walks in 2-2/3 innings of relief. Holland won 12 games and lost seven this season.
“You can have all the experience you want, but when you run into a team that is hot, experience has nothing to do with it,” Rangers manager Ron Washington said.
The A’s are just the third team in MLB history to win a division while spending just one day in sole possession of first place, joining the Minnesota Twins (2006) and the Giants (1951).
Japan’s Hiroki Kuroda pitched seven solid innings, while Robinson Cano and Curtis Granderson each homered twice as the Yankees crushed the Red Sox.
Cano led a 15-hit assault by going four-for-four with three runs scored and tying a career-high with six RBIs.
Granderson drove in four runs for New York, who have belted a league-best 245 home runs to eclipse their previous season record of 244.
Kuroda (16-11) did his part by limiting Boston to just two runs and scattering seven hits. He is an impressive 4-1 over his past six starts.
Red Sox starting pitcher Daisuke Matsuzaka (1-7) was roughed up for five runs and six hits in just 2-1/3 innings. Japan’s Matsuzaka, who finished with a dismal 8.13 earned run average, was likely making his last start of a lucrative six-year contract with Boston.
Cody Ross went two-for-three with an RBI single for Boston.
Michael Morse, Tyler Moore and Ryan Zimmerman each blasted home runs as the Washington Nationals clinched the National League’s top seed with a 5-1 win over the Philadelphia Phillies on Wednesday.
