Two rookies, Mookie Betts and Xander Bogaerts, led Boston's offensive barrage. Betts was 3-for-5 with a homer while Bogaerts went 4-for-5 with a homer.

Bogaerts is the first Red Sox rookie with at least four hits at Yankee Stadium since Jim Rice in 1975. He is also the youngest Red Sox with at least four hits against the Yankees since a 21-year-old Carl Yastrzemski on July 9, 1961.

Here's a look at what the duo accomplished together: • First pair of Red Sox rookies to both homer in the same game vs the Yankees since Phil Plantier and Bob Zupcic did so on September 21, 1991. • First pair of Red Sox rookies to both homer in the same game at Yankee Stadium since the rookie rules were established in 1958. • First Red Sox rookies to have at least three hits in the same game vs Yankees since the rookie rules were established in 1958.

Shane Greene started for the Yankees and delivered his worst start in pinstripes, allowing six runs before being removed in the third inning. It was the 54th game started by a Yankee rookie pitcher this season, tying the franchise record set in 1986 and 1991.

McCann can do it The Yankees kept their playoff hopes alive on Wednesday with a 5-1 win over the Red Sox, snapping their three-game skid.

Brian McCann earned his pinstripes at the plate, going 4-for-4 with a homer and three RBI. McCann is the first Yankee catcher in franchise history with at least four hits and at least three RBI vs Red Sox at Yankee Stadium (old or new).

The home run was McCann's fifth of the season against the Red Sox and the four hits gave him 18 against the AL East rival. The only other Yankee catchers in last 100 years with 15-or-more hits and five-or-more homers against the Red Sox in a season were Yogi Berra (1956) and Jorge Posada (2003).

Dellin Betances struck out two batters in the eighth inning, giving him 122 strikeouts this season. That ties Goose Gossage for the second-most all-time by a reliever in a single season in Yankee history. The only player with more is Mariano Rivera, who had 130 in 1996.

Bank on Chase The Yankees won the rubber game of the series in dramatic finish, rallying in the bottom of the ninth inning to beat the Red Sox 5-4.

Mark Teixeira tied the game with a solo homer to lead off the ninth. The only other Yankee first baseman in the last 75 years to hit a game-tying homer in the ninth inning or later against the Red Sox was Don Mattingly on June 14, 1984.

Chase Headley delivered the game-winning homer two batters later, sending a 3-2 pitch into the right field seats for the walk-off win. The only other Yankee in the “pitch count era” (since 1988) to hit a walk-off homer in a 3-2 count against the Red Sox was Derek Jeter on April 5, 2005.

The last time the Yankees hit a game-tying homer in the ninth inning and walk-off homer later in the same inning was May 17, 2010 against the Red Sox, when Alex Rodriguez tied the game with a two-run homer in the ninth inning and Marcus Thames won it one out later.

David Ortiz gave the Red Sox an early 3-0 lead with a solo homer in the first inning and a two-run blast in the third inning. It was his fourth career multi-homer game as a Red Sox at Yankee Stadium, matching Manny Ramirez for the most such games with two-or-more homers by any Red Sox player in the Bronx.
