Reds call up reliever Layne Somsen to help struggling bullpen

CINCINNATI -- The Cincinnati Reds have called up right-handed reliever Layne Somsen from Triple-A Louisville to help their overworked bullpen at the start of a series against the Pittsburgh Pirates.

Somsen was called up to the majors for the first time last month and spent three days in Cincinnati without appearing in a game. He was a 22nd-round pick in the June 2013 draft.

Cincinnati's bullpen has given up at least one run in 25 of the last 26 games. It's last in the majors with a 6.59 ERA and 27 homers and 63 walks allowed in 32 games.

The Reds optioned outfielder Kyle Waldrop to Louisville on Monday to open a roster spot. He was called up Sunday but didn't play against the Brewers.
