SAN FRANCISCO (Interstat) — Landen Roupp pitched 7 2/3 innings of two-hit ball and Casey Schmitt delivered a tiebreaking three-run homer in the seventh inning as the San Francisco Giants defeated the Miami Marlins 6-3 on Sunday evening at Oracle Park.

The Giants and Marlins both moved to 13-15 on the season with the result, splitting a three-game series. San Francisco won the second game of the set Saturday while Miami took the opener Friday.

Roupp (5-1) allowed three earned runs, walked one and struck out six, lowering his ERA to 2.08 across his past three starts. He yielded just a second-inning home run to Graham Pauley and scattered three additional base runners over his tenure. Erik Miller recorded the final four outs for his second save of the season.

Miami starter Max Meyer turned in a strong outing, working five innings of four-hit ball without allowing an earned run while striking out five, but the Marlins bullpen could not hold a 3-1 lead.

The Marlins grabbed the game’s first runs in the top of the second inning. Xavier Edwards walked, Liam Hicks singled and Pauley smashed a three-run homer to right field, his first of the season, giving Miami a 3-0 advantage.

San Francisco answered in the third. With one out, Jung Hoo Lee singled and Matt Chapman was hit by a pitch. Luis Arraez grounded into a force out that scored Lee when Miami shortstop Otto Lopez made a throwing error, cutting the deficit to 3-1.

The score remained unchanged until the sixth. Schmitt led off with a walk for the Giants, and Rafael Devers followed with a double to center field, scoring Schmitt. One out later, Drew Gilbert singled to left field, plating Devers to tie the game 3-3.

In the seventh, San Francisco broke the deadlock with a three-run rally. Lee singled and Chapman walked, both advancing on a sacrifice bunt by Arraez. Schmitt then launched a 1-0 pitch to left-center field for his fourth home run of the season, scoring Lee, Chapman and himself to put the Giants ahead 6-3.

Miami never threatened again. After Schmitt’s homer, the Giants added a walk and a strikeout in the inning, then retired the side in order in the eighth and ninth. Miller worked the final 1 1/3 innings, striking out one and allowing no hits.

Andrew Nardi (1-1) took the loss for Miami, surrendering three runs on two hits and two walks over one inning of relief.

The Marlins managed only two hits in the game, both coming in the second inning. Pauley’s homer accounted for the team’s lone extra-base hit and Miami’s only runs. Edwards reached base twice, walking once and drawing a hit-by-pitch.

For the Giants, Lee finished 4-for-5 with two singles, a triple and two runs scored. Gilbert went 2-for-4 with an RBI. Devers doubled and drove in a run, and Schmitt reached base three times, walking twice and homering.

The game lasted 2 hours, 12 minutes before an announced crowd of 40,445.

Miami’s offense struggled to generate any momentum after the second inning. Following Pauley’s homer, the Marlins went hitless over the final seven frames. Roupp retired 13 consecutive batters at one point, from the third inning until the eighth, when Heriberto Hernández walked with two outs. Roupp then struck out Jakob Marsee to end his evening.

Meyer departed after five innings having thrown 82 pitches. He was replaced by Calvin Faucher, who gave up two runs in the sixth on three hits and a walk. Anthony Bender tossed a scoreless eighth inning for Miami.

The Marlins next travel to Los Angeles for a three-game series against the Dodgers beginning Monday. The Giants open a four-game road trip Tuesday in Philadelphia against the Phillies.

Sunday’s game marked the first time this season that both teams entered with identical records at 13-15. San Francisco improved to 7-7 at Oracle Park, while Miami fell to 6-9 on the road.
