Adrian Gonzalez had only been in Los Angeles for a couple of hours and was wearing his Dodgers uniform for the first time when he found himself rounding the bases at Dodger Stadium.

One of the four players acquired in a blockbuster trade with the Boston Red Sox, Gonzalez sent the second pitch he saw as a member of his new team into the lower seats in the right-field corner for a three-run home run, giving the Dodgers a 4-1 lead over the Miami Marlins in the first inning.

Gonzalez's 16th home run of the season came on an 0-1 pitch from Miami right-hander Josh Johnson, scoring Luis Cruz and Matt Kemp.

The Dodgers' new first baseman -- replacing James Loney, who was sent to Boston as part of the nine-player trade -- struck out in his next two at-bats.

Gonzalez, who is batting .300 with 86 RBIs this season, arrived in L.A. on a flight from Boston on Saturday with pitcher Josh Beckett and utility man Nick Punto, who were also included in the deal that was completed earlier in the day.
