BALTIMORE — The Mariners made a swap of relievers to freshen up an overworked bullpen as they head into the final series of their grueling four-city road trip.
On Monday morning, Seattle selected the minor league contract of right-hander Christian Bergman and added him to the 40-man and 25-man roster. To make room on the active roster, right-hander Dan Altavilla was optioned to Class AAA Tacoma. Altavilla mopped the Mariners mess of a loss on Sunday in New York, pitching the final three innings in a 10-1 loss. The career-high usage in one game would’ve made him unavailable till at Wednesday at the earliest.
