NEW YORK — Major League Baseball’s end-of-season average salary topped $4 million for the first time, according to final calculations released by the players’ association.

The union said Friday that the average finished at $4,097,122. That marked a 3.3 percent increase from last year, when the average rose just 0.35 percent to $3,966,020, the lowest rise since 2004.

The commissioner’s office said its final average was $3,955,920, up 3.4 percent from last year’s $3,825,967. The union includes a pro-rated share of option buyouts that may be earned if the option is declined, while MLB does not take those into account in its average.
