The Brewers acquired Matos from the Giants on Monday in exchange for cash considerations.
Matos had been designated for assignment by the Giants last week and will now join a Brewers team that was in the need for some position player depth as they navigate injuries. The 24-year-old Matos is a former top prospect but has managed just a .231/.281/.369 batting line in 593 career plate appearances at the big-league level. He is out of minor-league options, so Matos will go directly onto the major-league roster.
