After catching for 269 pitches and watching his beleaguered bullpen escape jam after jam in extra innings, Buster Posey took matters into his own hands.

Posey homered with one out in the 17th inning for the latest walk-off homer in San Francisco history as the Giants beat the Cincinnati Reds for the first time this season with a 3-2 victory Friday night.

Nationals third baseman Anthony Rendon went 6-for-6 with three home runs and 10 RBIs on Sunday against the Mets, becoming just the second player in Major League Baseball history to have a game that included six hits, three home runs and 10 RBIs.

Walker Cooper is the other player. He went 6-for-7 when he had three home runs and 10 RBIs for the Reds against the Cubs on July 6, 1949.

"I may have had three home runs in high school," Rendon said of his historic game, "but never like that with the RBI."
