The San Francisco Giants worked their extra-inning magic on the visiting New York Mets once again on Sunday afternoon, getting a walk-off, opposite-field home run from Mike Yastrzemski in the bottom of the 12th for a 3-2 victory.
The win was the Giants’ third in the four-game series, all in extra innings. They prevailed 3-2 in 16 innings and 1-0 in 10 on Thursday and Friday before getting overpowered 11-4 on Saturday.
“We proved something to ourselves, that we can win a game when we’re down, that we can win a game when we go to extra innings,” Yastrzemski said. 
“So to be able to come through in those situations, it gives you all the confidence in the world.” 
Yastrzemski’s homer, his ninth in just 48 games with the Giants, came off the sixth Mets’ pitcher, Robert Gsellman (1-2), on a full-count pitch with one out. The left-handed hitter sent a high fly just a row or two deep into the left field bleachers. Trevor Gott (6-0) got the win after pitching a scoreless top of the 12th, capping a run of six relievers who held the Mets to two hits over the final seven innings.
For the third time in the low-scoring series, neither starting pitcher got a decision after both pitched well.
Giants left-hander Conner Menez went five innings in his major league debut, allowing two runs and three hits. He walked two and struck out six.
Both runs off Menez came in the form of solo home runs in the second inning by the Mets’ Michael Conforto, his 18th, and Amed Rosario, his 11th.
A second Giant playing in his first major league game, third baseman Zach Green, had an even splashier debut, contributing a single to his team’s first run in the second inning before ripping an RBI double that scored Buster Posey with the game-tying tally in the fourth.
That’s all the Giants got off Mets starter Steven Matz in his six innings, during which he allowed six hits and a walk. He struck out six.
Green finished the day with two hits, as did Posey, for the Giants, who took the season series from the Mets 4-3.
J.D. Davis had a single and a third extra-base hit, a double, for the Mets, who completed a 5-4 trip.
The Giants out-hit the Mets 7-5 en route to their fifth straight extra-inning win, their fourth of the week. They are now 9-2 in extra innings this season.
The Mets lost their seventh straight extra-inning affair, four to the Giants, and fell to 3-8 in overtime this season.

Twins top A’s on Kepler’s 
walk-off single
Max Kepler went 3-for-6 with four RBIs and drove in the winning run with a two-out single in the bottom of the ninth as the Minnesota Twins rallied for a 7-6 victory over the Oakland A’s on Sunday afternoon in Minneapolis. Kepler also homered and doubled as the Twins won for just the second time in seven games.
Ehire Adrianza had tied the game earlier in the ninth off Liam Hendriks (4-1), who was pitching in his third consecutive game, when he tripled off the top of the wall in right field, driving in Luis Arraez who had singled.
Arraez finished 3-for-5 to increase his batting average to .381 in 113 at-bats. Adrianza went 3-for-5 with two runs and two RBIs. Kohl Stewart (2-1) picked up the win with one inning of scoreless relief.
Josh Phegley homered and drove in three runs, and Matt Chapman had two hits for Oakland, which lost for just the second time in 10 games despite garnering nine walks off five Minnesota pitchers.
The Twins took a 1-0 lead in the first inning when Kepler led off with a double and scored on a double by Jorge Polanco.
Minnesota extended its lead to 4-0 in the second when Kepler hit his team-leading 24th home run of the season, driving in Adrianza, who had doubled, and Jason Castro, who had walked. It was the 182nd homer of the season for Minnesota, tops in the majors.
Oakland cut it to 4-2 in the fifth inning when Jurickson Profar drew a one-out walk and Phegley followed with his 10th home run of the season.
Minnesota increased its lead to 5-2 in the bottom of the fifth on an RBI single by Adrianza, but the A’s chipped away with a pinch-hit sacrifice fly by Chad Pinder in the sixth and cut the lead to 5-4 an inning later when Marcus Semien walked, advanced to third on a double by Chapman and scored on a wild pitch by reliever Trevor May.
