An error by Giants shortstop Art Fletcher led to three first-inning unearned Boston runs off Mathewson. Single tallies in the second and fourth by the Giants cut the lead to 3–2. Another error by Fletcher, who failed to tag Harry Hooper on a stolen base attempt, led to a fourth Boston run in the fifth when Yerkes followed the error with an RBI triple. In the top of the eighth Boston returned the favor, allowing New York to strike back for three runs. Left field at brand-new Fenway Park was unique for a incline in front of the wall (later to be called "The Green Monster"). Red Sox left fielder Duffy Lewis was so proficient at negotiating this incline that it was first named "Duffy's Cliff" in his honor, but this time Lewis tripped on the hill and failed to catch Fred Snodgrass' fly ball, putting him on first base. He scored on Murray's double, and two batters later third baseman Buck Herzog hit a two-run double to give New York a 5–4 lead.
