Casey Schmitt hit a go-ahead home run for the second consecutive day, Landen Roupp ran his personal winning streak to four games and the San Francisco Giants closed out a winning homestand with a 6-3 victory over the Miami Marlins on Sunday afternoon.

Jung Hoo Lee had four hits, including a triple, and scored twice for the Giants, who rebounded from a 9-4 loss on Friday to win a second straight series and complete a 4-2 week at Oracle Park.

Roupp (5-1) served up a three-run homer to Graham Pauley, his first of the season, in the second inning before taking a two-hitter and 6-3 lead two outs into the eighth. Erik Miller finished up from there, retiring all four batters he faced to pick up his second save.

Roupp walked two and struck out six in the longest outing of his three-year career.

A throwing error on Marlins shortstop Otto Lopez allowed the Giants to get on the board in the third and RBI hits by Rafael Devers and Drew Gilbert drew the hosts even at 3-3 in the sixth before Schmitt's difference-making blast in the seventh.

Lee set the stage for Schmitt's heroics with a leadoff single off Miami's third pitcher, Andrew Nardi (1-1), after which Matt Chapman drew a walk.

Luis Arraez sacrificed the baserunners to second and third, and with Devers moving on-deck, the Marlins elected to pitch to Schmitt, who launched his fourth homer of the year over the barrier in left-center field for a 6-3 lead.

Schmitt, who also walked, scored twice and Gilbert had two hits for the Giants, who have gone 7-3 since a 6-12 start. Lee's four hits were half of San Francisco's total.

The Marlins managed just two hits, both coming in the three-run second. Liam Hicks followed Xavier Edwards' walk with a single, after which both jogged home on Pauley's home run.

Miami starter Max Meyer was pulled after five innings, having limited the Giants to just one run, which was unearned. He allowed four hits and one walk while striking out five.
