CLEVELAND - Jake Westbrook struck out a career-high nine and Grady Sizemore had four hits as the Indians, fourth-place finishers a year ago, clinched their first American League Central title since 2001 with a 6-2 win over the Oakland Athletics on Sunday.

The Indians became the second team in the majors to clinch. The Red Sox assured themselves of at least the AL wild-card spot Saturday night.

When reliever Rafael Betancourt struck out Oakland’s Mark Ellis for the final out and his second save, the crowd of 40,250 erupted as one and the right-hander jumped into catcher Victor Martinez’s arms as the Indians poured onto the infield to celebrate.

John Lackey and the Los Angeles Angels clinched their third AL West title in four years as Anaheim defeated Seattle 7-4.

After losing two in a row to the Mariners, the Angels clinched in their final home game of the season. Wearing red and roaring, a sellout crowd was on its feet to see manager Mike Scioscia’s team return to the playoffs after missing out last season.

Macier Izturis and Casey Kotchman homered in the third inning and that was enough for Lackey (18-9). The Angels ace held Seattle to two runs in seven innings.
