The Rangers third baseman has homered in four consecutive games for the first time in his career and entered Wednesday's regular-season finale against the Angels having homered in 12 of his last 15 games.
"I am seeing the ball well," Beltre said. "But the main thing is that when I am getting a good pitch to hit, I'm not missing it. That is the key.
"What is good about this is that it is exactly where I want to be with the playoffs around the corner. Hopefully it can carry on and I can contribute."
It marks only the second time in Rangers history that a player has hit 12 long balls in 15 games. The last time it happened was in May 1968 by Frank Howard.
Crushing the ball in September, just like many of his teammates, Beltre leads the Majors in home runs (12) and RBIs (29) in the month.
"He's producing and swinging the bat," manager Ron Washington said. "He is really locked in. He is an 18-year veteran, and once they find it, they usually don't lose it."
