DENVER (AP) — The Diamondbacks and Rockies wrap up a pivotal four-game series this afternoon in Colorado. Both teams are chasing the NL West title. Colorado leads the division by 1½ games over the Dodgers, while Arizona is 3½ back. Clay Buchholz makes his first career start at Coors Field against Rockies left-hander Kyle Freeland, who is 8-2 at home this season.

WASHINGTON (AP) — The NL Central-leading Cubs have a one-day pit stop in Washington to make up Sunday's rainout. They're not happy about breaking up their homestand and losing a scheduled day off, because it means going 30 straight days without one. Cubs left-hander Mike Montgomery faces right-hander Joe Ross, who makes his season debut for a Nationals team that's won five straight.

BALTIMORE (AP) — The surging Athletics go for a three-game sweep of the Orioles, the worst team in the majors. Oakland embarrassed Baltimore 10-0 last night to improve to an AL-best 34-15 since the All-Star break and close within a game of the New York Yankees for the first AL wild card. The A's have won six straight overall and are 5-0 against the Orioles this season. Baltimore has lost six in a row to fall to 41-104, the eighth time this season the Orioles have dropped at least six consecutive games.

CINCINNATI (AP) — The Cincinnati Bengals host the Baltimore Ravens in the NFL's Thursday night game. Their last meeting was in Baltimore in the final game of last season, when a Bengals touchdown in the closing seconds kept the Ravens out of the playoffs. The Ravens opened this season with a blowout win over the Buffalo Bills, while the Bengals beat the Indianapolis Colts.

FAIRFAX, Va. (AP) — The Seattle Storm has won the WNBA championship in a three-game sweep of the Washington Mystics. Breanna Stewart scored 30 points in the 98-82 victory.
