Henriksen batted and threw left-handed.
A baseball card from 1912, which was produced by a cigar company, calls him the "viking descended outfielder".
He is described as a "slashing" hitter who quickly gathered interest from scouts of the Boston Americans.
In the Major Leagues he was typically used as a pinch hitter, and as a consequence he only had an average of 1.9 plate appearances per game played over the course of his career.
He never became a regular in the lineup but instead he served as a backup for Red Sox' famous outfield trio consisting of Tris Speaker, Harry Hooper and Duffy Lewis.
In 1915 he appeared in 73 regular season games and 2 additional games in the playoffs which was his personal record.

Defensively Henriksen exclusively played the outfield.
He had most appearances (61) as right fielder, second most (42) as left fielder and finally some (22) as center fielder.

Probably the greatest moment in Olaf Henriksen's professional baseball career occurred when Red Sox manager Jake Stahl decided to use Henriksen as a pinch hitter for Hugh Bedient in the 7th inning of the eighth and final game of the 1912 World Series.
Boston was behind by a run and the opposing pitcher was Christy Mathewson, later to become one of the first five players elected into the Hall of Fame.
With a late swing Henriksen hit a curveball from Mathewson directly against 3rd base.
The ball ricocheted off the base and went far enough into foul territory for the runner on 2nd to score.
Henriksen, whom the New York World described as "the confounded son of Thor", ended up with a double.
The Red Sox went on to win the game and thereby the World Series.

On March 17, 1916 the Red Sox played an internal spring training match.
Babe Ruth launched a long shot which looked like a sure home run, but Olaf Henriksen managed to surprise everybody by literally running through the wooden outfield fence and catching the ball.

Olaf Henriksen is furthermore one of the few players to ever have pinch hit for Babe Ruth.
On June 7, 1916, when Ruth had pitched 7 innings versus the Cleveland Indians, Henriksen was substituted into the game and got a base on balls, which ultimately tied the score at 1–1.
The Red Sox won the game 2–1.
