Watch Boston Red Sox Vs. New York Yankees Live Online — Baseball’s Fiercest Rivalry, Streaming Free

Baseball fans can watch the Boston Red Sox vs. New York Yankees game live online to see the third of 18 games between baseball’s oldest and fiercest rivals in 2015. Sunday’s game features an intriguing pitching matchup of Number One starters for each team — two pitchers who appear to be headed in opposite directions.

The Sunday night game, broadcast nationally by ESPN and streaming free on the web and mobile devices via WatchESPN, will close out the first three-game series of the year between the two America League East Division powerhouses, this one from Yankee Stadium in the the Bronx, New York.

The Red Sox won the first two games, starting with a historic but grueling 19-inning marathon — a game that started at 7:05 p.m. on Friday but did not wind up until about 2:13 a.m. on Saturday morning.

The game also had a delay when the lights went out in Yankee Stadium, making the official time of game six hours and 49 minutes. That made the game the longest ever played, in terms of time, by the Red Sox, a franchise that has existed since 1901.

The game broke the team mark set on August 25, 2001, when the Red Sox played an 18-inning game against the Texas Rangers in Arlington, Texas. But the Red Sox lost that six-hour, 35-minute game 8-7.

Friday’s 19-inning affair had the second-most innings played in any game that Boston ever won.

The Red Sox won again on Saturday, but within the regulation nine this time, as the Yankees made a series of defensive miscues that opened the floodgates for Boston to plate eight runs in what turned out to be an 8-4 decision.

Sunday night’s game, starting at 8 p.m., features a mound duel between the team’s top starting pitchers. Boston’s Clay Buchholz opened the season last Monday with a masterful, seven-inning, three-hit shutout performance against the Philadelphia Phillies.

For the Yankees, Masahiro Tanaka continues to pitch with a torn ligament in his right arm — and it showed on Opening Day when he was chased from the game after just four innings by the Toronto Blue Jays.

The Yankees hope Tanaka can pitch through the injury more effectively this time, allowing the Bronx Bombers to stave off the sweep by their arch-rivals to the northeast. The rivalry then resumes on May 1, when the Yankees land in Boston for three games at Fenway Park.
