How a Smart Baserunner Can Exploit the Basepath Rules

In the game of baseball, as in all major sports, coaches instruct their players to take what the defense gives them. Conversely, it would be a good idea for defensive players to take what the offense gives them. Let’s look at the following play.

The Cardinals and Pirates played two games on Sept. 18 at PNC. Because the nightcap was a makeup game of Aug. 12 scheduled for St. Louis, the Cardinals were the home team and batted last.

In the bottom of the sixth, the Redbirds had runners on second and third and one out when Tyler O’Neill hit a ground ball to Pirates’ third baseman Ke’ Bryan Hayes. Paul Goldschmidt, the runner on third, broke for the plate. Instead of remaining in foul territory in his sprint to the plate as most runners do, he moved over into fair territory and got in the throwing lane of Hayes to catcher Jacob Stallings.

Hayes’ throw got by Stallings and Goldschmidt scored easily to make the score 3-2 in a game the Cardinals won, 7-2. Hayes was charged with an error.

The question is, did Goldschmidt run out of the baseline? Did he interfere with Stallings?

Ruleball Comments

Goldschmidt made a wise and legal running play. Rule 5.09 (b) (1) reads, “Any runner is out when he runs more than three-feet away from his base path to avoid being tagged unless his action is to avoid interference with a fielder fielding a batted ball. A runner’s base path is established when the tag attempt occurs and is a straight line from the runner to the base he is attempting to reach safely…” (The OBR uses the word basepath for baseline).

Simply said, “The only time a runner has a restricted baseline is when he is avoiding a tag.” Goldschmidt was not avoiding a tag and by rule was within his rights to travel from third to home in fair territory.

Goldschmidt forced the Pirates to take what the offense gave them (the third base line side of the plate) but they (Hayes and Stallings) did not adjust. Most teams, out of habit and tradition, would not make the adjustment.

Goldschmidt legally dictated the position of Stallings moving to the third base side of the plate which he failed to do. You can’t blame Stallings because it was probably the only time he ever had to deal with a runner staring him in the eye as he approached the plate.

There is no doubt that Goldschmidt’s intentions were to disrupt the throwing lane between Hayes and Stallings. Goldschmidt had a good read where Hayes fielded the ball- not far from third base. By taking the path to the plate the way he did, he put a great deal of pressure on Hayes.

Goldschmidt’s actions would be illegal if in his approach to the plate he deviated from his running lane and targeted the catcher. The way the play is umpired, he did not do this, and his actions were legal. In my spring training presentations over the years, I have used several examples where runners have successfully taken this unconventional route to the plate and disrupted the throw.

As stated, unless a runner is avoiding a tag, he has no baseline. Therefore, the runner on first base can take advantage of a liberal running lane when running from first to second on the 3-6-3 or 3-3-6. The runner running from first to second can run at the target (glove) of the fielder receiving the throw without violating any baseline restriction. By doing that, the runner makes the throw from the first baseman more difficult and legally obstructs the vision of the fielder receiving the throw.

A smart runner can induce a pick-off throw at first base and head to second in the direction of the target of the fielder who is receiving the throw.

It has been my experience that most teams do not practice the third to home throw, or the first to second throw with a runner in a position to the disrupt the throw. The chances for success, especially third to home are high.
