Even before he made his major league debut in August, and especially after taking over at third base in the postseason, Xander Bogaerts has been causing a stir among Red Sox fans.

But it’s barely a ripple compared to the hubbub in his country. In Aruba, it’s been Xandermonium.

“It’s hectic down there,” Bogaerts said last night before Game 5 of the World Series. “It’s something else. So many people wearing my jerseys, I can’t even imagine.”

Bogaerts is the fifth native Aruban to play in the majors, joining outfielder Gene Kingsale and pitchers Calvin Maduro, Sidney Ponson and Radhames Dykhoff, all of whom debuted since 1996 and none of whom are still active.

So, if you think expectations for the just-turned 21-year-old top prospect are high in New England, they’re off the charts in Aruba, where friends and family aren’t the only ones counting on Bogaerts bringing a World Series ring back to the island.

Consider this: Bogaerts went 0-for-6 with four strikeouts in the first two games of the World Series, and when the Sox arrived in St. Louis to prepare for Game 3, text messages from home were piling up.

“Everyone was like, ‘Bogaerts, what’s going (on)?’ ” he said. “I was like, ‘Don’t panic. Relax.’ It’s baseball. You have ups and downs. You’ve just got to relax and enjoy the game.”

Bogaerts’ talent is both considerable and obvious. But his poise and confidence, especially during the pressure-packed postseason, are what have most impressed the Red Sox, who turned to him to replace struggling third baseman Will Middlebrooks before Game 5 of the AL Championship Series against the Tigers.

Sure enough, Bogaerts doubled and scored in Game 5, then impressively drew a pair of walks after being down two strikes against presumptive Cy Young Award winner Max Scherzer in Game 6.

“Am I nervous? Definitely. I’m human,” Bogaerts said. “I’m definitely nervous before the game. But during the game I try to stay as calm as possible and just enjoy the moment. You don’t get here too often.”
