Willy Adames led off the game with a homer and finished with a career-high-tying four hits to go with two RBIs and the San Francisco Giants' offense finally exploded during a 9-3 victory over the host San Diego Padres on Tuesday night.

Jung Hoo Lee had three hits and three RBIs, and Matt Chapman (solo homer) and Rafeal Devers had two hits apiece as the Giants racked up 16 hits. San Francisco totaled four runs and 19 hits over its first four games of the season.

Heliot Ramos drove in two runs for the Giants, who went 6-for-12 with runners in scoring position while beating San Diego for the second straight night. Adames collected four hits in a game for the 12th time in his career.

Giants starter Logan Webb (1-1) gave up three runs and three hits over six innings. He struck out five and walked four.

Jackson Merrill and Miguel Andujar had RBI hits for the Padres, who have lost four of five games to start the season.

German Marquez (0-1) struggled in his San Diego debut, serving up two homers while pitching just three innings. He gave up four runs, eight hits and one walk, and he struck out one.

San Francisco broke the game open with four runs in the sixth inning.

Harrison Bader doubled and Patrick Bailey drew a walk from Kyle Hart. One out later, Adames stroked an RBI single to make it 5-3.

Devers reached on an infield hit to load the bases before Bradgley Rodriguez replaced Hart. Ramos greeted Rodriguez with a two-run single, and Luis Arraez followed with a sacrifice fly to make it 8-3.

Lee had an RBI bloop single in the ninth for the final Giants' run.

Adames got the Giants going by hitting the second pitch of the game for a homer to left.

Later in the inning, Ramos drew a one-out walk and Chapman singled with two outs. Lee followed by ripping a two-run double off the wall in right.

Chapman made it 4-0 leading off the third when he sent a 2-1 fastball over the fence in left.

The Padres responded in the bottom of the third. Fernando Tatis Jr. and Manny Machado walked with one out before Merrill hit a run-scoring single to right to plate the first run.

Xander Bogaerts followed with a fielder's choice to score Machado, and Andujar lined a single to right to score Merrill and pull San Diego within one.
