The Mariners acquired Kennedy from the Giants on Sunday in exchange for cash considerations.
San Francisco designated Kennedy for assignment earlier in the day, but the Giants didn't have to wait long to find a trade partner. The 27-year-old Kennedy played sparingly during his four-week stint in the majors with San Francisco, going 0-for-7 with a walk and three strikeouts over seven contests. Kennedy has no minor-league options remaining, so the Mariners will need to open up a spot for him on the 26-man active roster. He'll serve as a depth piece in the infield and outfield and could make occasional starts against left-handed pitching.
