Brooks signed a minor-league contract with the Padres on Wednesday.
Brooks struggled in his first 12 regular-season games as a big-leaguer, going just 3-for-25 with an RBI and six strikeouts with the Giants last year. However, he slashed .302/.410/.453 with 58 RBI over 407 plate appearance in the minors, which is good enough for the Padres to bring him in as organizational depth at first base.
