1915 Yankee Home Run hitters: 28 home, 3 road.

While checking to see if Red Sox pitcher Babe Ruth was among the American League leaders in Ruth's 1915 rookie season with his four Home Runs, I noticed that five Yankees were among the top 15 (there were lots of ties in the top ten).

The first 3 of Ruth's 4 Home Runs were against the Yankees, the first two in New York at the Polo Grounds, the third in Boston in Fenway Park. Ruth hit all four of his 1915 homers in games in which he only pitched. He also pinch hit in 12 games, including one in which he remained in the game and pitched.

Ray Caldwell, like Ruth, was a starting pitcher. In 1915:
19-16, 2.89 ERA, 305 Innings

Caldwell started pitching in 1910 and the four homers he hit in 1915 were his first and most. He pitched through 1921 and hit four more homers: two in 1917 and one each in 1918 and 1921. Two of his four 1915 homers were hit as a pinch hitter; three were hit in the Polo Grounds:

Like teammate Boone, all his 1915 homers were at home in the Polo Grounds.

Fritz Maisel played for the Yankees 1913-1917 and was the starting third baseman in 1914 and 1915.

Maisel hit 6 career Home Runs. In 1915 Maisel hit 2 IPHR and one that bounced over the fence (rule changed after 1930 season). His second career home run was IPHR hit off Babe Ruth.

Wally Pipp played first base for the Yankees 1915-1925. Pipp was the first Yankee to lead the AL in HR:

1915 AL  4 (9th)

1916 AL  12 (1st)

1917 AL  9 (1st)

1919 AL  7 (8th)

1920 AL  11 (7th)

1924 AL  9 (10th)

In 1915 all four of Pipp's HR were hit in the Polo Grounds.

The Polo Grounds was owned by the New York Giants of the National League. The Yankees rented the Polo Grounds from the Giants 1913-1922. Above are 1915 AL parks sorted by HR hit. The Polo Grounds had the most AB and HR in the AL in 1915. HR hit in the Polo Grounds in AL in 1915 were more than twice any other AL park.

During the first 7 years that the Yankees played their home games in the Polo Grounds, it had the most Home Runs hit every season except 1913 when it was third.

Babe Ruth joined the Yankees in 1920 so it's surprising that the Polo Grounds led AL only in 1920.  In 1921 seven more HR were hit in Shibe Park in Philadelphia and in 1922:
Shibe Park in Philadelphia 168
Sportsman Park St. Louis 111
Polo Grounds New York 101
