Manager Bob Melvin told reporters Sunday that Rafael Devers has been dealing with a groin issue ever since the Boston Red Sox traded him to the San Francisco Giants.

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.
