Rafael Devers said he knew immediately after hitting the first home run of his San Francisco Giants career on Saturday against his former teammates on the Boston Red Sox that the ball was going out of Oracle Park.

Rafael Devers' first home run as a member of the Giants came in a game against his former team: the Boston Red Sox.

With his first homer as a Giant, a two-run, opposite-field shot, Devers powered San Francisco to a 3-2 win over the Boston Red Sox — the only major-league team Devers had known for more than a decade. In Boston, Devers blossomed into one of baseball’s best players. In San Francisco, the Red Sox can only watch their former star from afar.
