Pedro Alvarez homered in the 19th inning and the Pittsburgh Pirates won the longest game in the majors this season, outlasting the St. Louis Cardinals 6-3 Sunday.
Adam LaRoche homered twice, Danny Espinosa hit a three-run shot in Washington's six-run eighth inning, and the Nationals beat the Miami Marlins 10-7 on Saturday night.
Aces Clayton Kershaw of the Los Angeles Dodgers and Ian Kennedy of the Arizona Diamondbacks exchanged brush-back pitches Monday night during their first head-to-head matchup of the season.

The Washington Nationals have known, or at least hoped, from Day 1 that Bryce Harper would be an "impact player" from the moment he hit the big leagues. But the way Harper arrived, hurriedly and out of necessity, and the way they allowed the idea that this might not be his moment, the Nationals did their best to temper expectations.
The question was simple enough: Why put 19-year-old Bryce Harper, the youngest player in the major leagues, in the No. 3 spot in the lineup already, only five games into his career with the Washington Nationals?
The Diamondbacks' field crew used a combination of cotton candy and lemonade to help disperse a swarm of bees that delayed the San Francisco Giants split squad's 11-1 win over Arizona for 41 minutes in the second inning Sunday.
After struggling for much of the season, the Los Angeles Dodgers are cruising when it comes to postseason honors.
