PITTSBURGH — A day after one of their worst offensive games of the season, the San Francisco Giants had their best.
Angel Pagan hit a grand slam during a seven-run fourth inning, Johnny Cueto shut down Pittsburgh into the seventh and the Giants clobbered the Pirates 15-4 on Tuesday night.
Conor Gillaspie also homered during the fourth among his four hits and Gregor Blanco scored three times for San Francisco, which won a night after having an eight-game winning streak snapped in a 1-0 loss to Pittsburgh.
“Whatever happened last night, this is just another game,” Pagan said. “Obviously we were trying to win a ballgame [Monday], but we didn’t. Today we just came with a brand new opportunity to go out there and try to put together the best at-bats possible.”
The Giants did plenty of that Tuesday. San Francisco, which also had a five-run eighth inning, had season highs in runs and hits (22).
Every Giants starter reached base at least once; all but Cueto had at least one hit. Brandon Belt and Buster Posey each had two hits and two runs.
Cueto moved into a tie for the National League lead in wins by allowing one run on four hits in 6.2 innings. He extended his career-best winning streak to eight and improved to 19-4 against the Pirates.
“I wasn’t aware of the number, but I know that after I lost the (2013) wild-card game against them, I told myself I needed to just concentrate and try to win as many games as I can,” Cueto said.
Recalled earlier in the day from Triple-A Indianapolis, Pittsburgh’s Wilfredo Boscan allowed one baserunner over the first three innings of his first major league start, but did not retire any of the seven batters he faced in the fourth.
Pittsburgh (34-37) has lost 11 of 13 to fall into sixth place in the NL wild-card race.
The first nine Giants who came up in the fourth inning reached base.
After Brandon Crawford drove in the game’s first run by drawing an 11-pitch walk, Pagan took the next pitch Boscan threw into the seats in right-center for his third homer of the season and second grand slam of his career.
“I don’t know whether the at-bat to Crawford took some steam out of him,” Pirates manager Clint Hurdle said, “but after that, you walk a guy and the mentality is you have to throw a strike and you throw a strike to a dead-red fastball hitter, the guy has a chance to ambush you.”
After Blanco doubled, Gillaspie homered.
“We finally broke through,” Giants manager Bruce Bochy said.
“It’s always good for hitters to get the second look and have a better idea what his ball is doing,”
