A look at what's happening around the major leagues Monday:

FOR THE CROWN

More from FoxSports

The Pirates get their best chance to catch up to the NL Central-leading Cardinals this week as they play a three-game set in Pittsburgh. Trevor Rosenthal blew a save against the Brewers on Sunday, and the banged-up Cardinals have lost two of three. Star catcher Yadier Molina (thumb) was scheduled to be re-examined.

GIANT CHALLENGE

The Giants trail the Dodgers by six games in the NL West with seven left to play, but can chip into that lead as they open a four-game set at home against Los Angeles. San Francisco leads the season series 9-6 - including 6-0 at AT&T Park - but face Zack Greinke on Monday before Clayton Kershaw opposes Madison Bumgarner Tuesday. Greinke has won both his starts against San Francisco this season. Jake Peavy pitches for the Giants.

KEEPING UP

Fresh off taking two of three from the first-place Rangers, the Astros continue their pursuit of an AL West title as they play at Seattle. Rookie Lance McCullers hasn't won since July 29 but has made a quality start in five of his past six outings, including a nine-strikeout performance against the Angels his last time out. Houston is 2 1/2 games behind Texas.

D.C. DUSTUP

The Nationals hope the only fireworks will be of the postgame variety as they play their final home game of the season, a makeup of a July 8 rainout against the Reds. Bryce Harper and Jonathan Papelbon fought in the dugout during Washington's 12-5 loss to the Phillies on Sunday, something for which Papelbon apologized for postgame. ''I'm in the wrong there,'' Papelbon said. ''For me, I can't allow that to happen in the middle of a game.''

OUTSIDE LOOKING IN

The Twins and Indians open a series as both teams try to gain ground in the crowded AL wild-card race. Minnesota is 1 1/2 games behind Houston for the final spot, while Cleveland is four games back of the Astros. Corey Kluber is tied for the AL lead with 15 losses after winning the AL Cy Young award last year.

INSIDE LOOKING OUT

The Royals and Cubs make up a May 30 rainout at Wrigley Field with both teams already assured of postseason berths. Kansas City has locked up the AL Central, but is limping to the finish with a 9-15 record this September. The Cubs are most likely headed for the NL wild-card game and are hoping to edge out Pittsburgh - or possibly St. Louis - for hosting rights in the contest.
