The Los Angeles Dodgers defeated the San Francisco Giants 8-0 on Tuesday night to clinch their third straight National League West title.

Clayton Kershaw, who has struggled in the postseason, tossed a one-hitter against the rival Giants. The Dodgers will face the New York Mets in a best-of-five division series.

"I've been through it now a bunch; I think this is my fifth postseason now," Kershaw said. "I don't know if you can get wiser from failing all the time. I know what that feels like."

The Dodgers earned a third straight playoff berth for the first time in franchise history and did so by snapping a seven-game losing streak at AT&T Park this year. It's also their sixth postseason berth in 10 years.

The Kansas City Royals are division championships for the first time in 30 years.

Kansas City defeated the Seattle Mariners 10-4 on Thursday night to clinch the American League Central crown.

"I've felt all along we would win this division," Ned Yost said. "I've got my eyes on a much bigger prize. This is the first step of it."

It is Kansas City's first division title since 1985, when George Brett led the Royals to the AL West crown en route to their only World Series championship.

"It's a huge accomplishment," Ben Zobrist said. "It hasn't been done here for a long time. There's a lot of guys in this clubhouse I've talked to that have toiled for years to get to this point, to win the division. For them to do it, you can see the kind of sigh of relief, the excitement in the organization."

The Pittsburgh Pirates defeated the Colorado Rockies 13-7 on Wednesday, allowing them to clinch a playoff berth for the third-straight year.

"We're happy with where we are," Andrew McCutchen said. "But we still have some work to do.

"We're not done. Got to keep going."

The Pirates secured at least a wild card as they chase first-place St. Louis in the NL Central. They trail by four games with a home series coming up against the Cardinals.

St. Louis and Pittsburgh are the only major league teams to lock up playoff trips so far.

The Cardinals have become the first team to clinch a postseason berth this year despite losing to the Cubs on Saturday.

The Cardinals fell at Wrigley Field, but manager Mike Matheny's team later sealed a playoff spot when San Francisco lost to Arizona. The Giants' defeat ensured St. Louis at least an NL wild-card slot.

St. Louis has the best record in the majors at 92-56
