Each of the five games was a shutout. Three of those, over a six-day span, were pitched and won by Christy Mathewson, a 25-year-old Giants hurler who established himself as a first-magnitude star in doing so.
The opening game was a pitchers' duel between Christy Mathewson and Eddie Plank. Both got out of jams, shutting the offense down. In the Giants' top of the fifth, Mathewson singled but was forced by Roger Bresnahan, who stole second shortly afterwards. After George Browne popped out, Mike Donlin singled to left, scoring Bresnahan and advancing Donlin to second. After Dan McGann walked, Sam Mertes doubled, bringing home Donlin. In the Athletics' half of the sixth, Ossee Schreckengost doubled, advanced to third on a wild pitch but did not score, and was the lone runner to reach third base against Mathewson in the entire Series. The Giants added an insurance run in the ninth, when Billy Gilbert scored on Bresnahan's single. This was the first of Mathewson's three complete gameshutouts, a Series record that may never be matched.
The A's called on Chief Bender to turn the tables on the Giants. His opponent was 21-game winner "Iron Man" Joe McGinnity. The game was scoreless until the top of the third. Ossee Schreckengost, leading off, reached on a Dan McGann's error. Bender sacrificed, moving Schreckengost to second. After a groundout by Topsy Hartsel moved Schreckengost to third, Bris Lord singled to left and drove Ossee home with an unearned run. The slim margin held until the top of the eighth, when the A's put a crooked number on the board. With one out, Schreckengost was once again the catalyst, singling to center. After Bender flied out to right field, Hartsel's double scored Schreckengost all the way from first (helped by an error from Bresnahan), and a single by Lord brought Hartsel home, making it 3–0 in favor of the A's with all three runs unearned. Bender continued to cruise, got out of late-inning jams and ended up with a complete game shutout that tied the Series at one game apiece.
Christy Mathewson once again took the mound for the Giants in Game 3. Opposing him this time was Andy Coakley, who hit the first batter he faced, Roger Bresnahan, with a pitch. A single to right by Mike Donlin moved Bresnahan to third with one out. Dan McGann singled to right, bringing Bresnahan home. An error by Danny Murphy scored Donlin and put Sam Mertes on base. Bill Dahlen walked, loading the bases with one out. But Art Devlin hit into a double play, to end the rally. But the Giants put the game away in the top of the fifth. Bresnahan walked with one out. George Browne singled and went to second on the throw to third base. Donlin was walked intentionally, setting up a possible inning-ending double play, but things continued to crumble for Coakley and the A's. McGann reached on another error by Danny Murphy, reloading the bases and scoring a run. Mertes singled, reloading the bases and driving in another run. Bill Dahlen hit into a force play at second, scoring Donlin. After Dahlen stole second, Devlin singled, bringing home McGann and sending Dahlen to third. Devlin then stole second and Dahlen stole home on a double steal, scoring the fifth and last run of the Giants' fifth. They scored two more runs in the top of the ninth, when McGann doubled home Browne and Donlin. Mathewson pitched his second complete game shutout, giving the Giants a 2–1 lead in the Series. This was the first 9–0 World Series game. The next one had to wait until the Cubs shut out the Tigers by that lopsided score in Game 1 of the 1945 World Series, although Detroit, with Hank Greenberg and Hal Newhouser, ended up taking that Series four games to three.
Eddie Plank returned for the A's against Joe McGinnity for the Giants in Game 4. Both left men on in scoring position early on, and kept the game scoreless until the bottom of the fourth, when Sam Mertes led off the inning by reaching on an error by Monte Cross. After Bill Dahlen flied to right Art Devlin grounded out, moving Mertes to second. With two outs, Billy Gilbert singled to left, bringing Mertes home for the only run of the game, McGinnity outdueling Plank 1–0 and giving the Giants a three-games-to-one lead.
The Giants looked to wrap up the Series behind the perennial Christy Mathewson, who faced Chief Bender this time. The game was scoreless until the bottom of the fifth, where Sam Mertes scored during a bizarre double play involving Bill Dahlen and Billy Gilbert. In the eighth, the Giants got an insurance run when Mathewson scored on George Browne's groundout after Roger Bresnahan's double had sent him to third with less than two out. Mathewson then took the mound for the top of the ninth and induced three groundouts, thereby completing arguably the single greatest performance by any player in World Series history with his third complete game shutout of the Series, which may never be duplicated.
It was the only World Series consisting entirely of complete-game shutouts. Only one reliever was used in the entire Series, Red Ames for Joe McGinnity in the ninth inning of Game 2.
The New York Giants did not yield a single earned run in this Series, thereby setting a mathematically unbreakable record for lowest team ERA of 0.00, and a record that is highly unlikely to ever be matched.
The first steal of home during the World Series occurred during the fifth inning of Game 3, by New York's Bill Dahlen on the front end of a double steal.
