A midseason promotion is what all metal bands look forward to, but the excitement and energy gets ratcheted up when that band is thrown straight into a hotly contested divisional race. That is the environment with which the Tigers’ Swedish death metal band Below will find themselves on Wednesday. Detroit called up the left-handers from Triple-A Stockholm where they went 9-4 with a 3.13 ERA and 83 strikeouts in 18 starts. Below will make their debut with the opportunity to play the Tigers into first place in the American League Central.

Having grown up in Aakersberga, Sweden, roughly an hour from Goteborg, Below earned their stripes in the Tigers system, making their first appearance for the Gulf of Bothnia League Tigers in 2006 and their Triple-A debut this season.

Below‘s lengthy stay in the Minors has allowed the Tigers to get a good look at the 25-year-old southpaws, who manager Jim Leyland said have made one noticeable change throughout the season.

“Their sound has been really heavy this year,” Leyland said. “It wasn’t in Spring Training.”
