The Twins traded Pereda to the Mariners on Tuesday in exchange for cash.
The Twins DFA'd Pereda on Friday after signing Victor Caratini, but the former will reclaim a 40-man roster spot now that he's been dealt to the M's. He won't take playing time away from Cal Raleigh, but Pereda could provide some quality organizational depth after slashing .308/.422/.465 across 192 Triple-A plate appearances last year.
