Changes could be in store for Giants

CHICAGO (AP) - Between the blown leads and the lack of hits, it wasn't a pleasant day for the San Francisco Giants at friendly old Wrigley Field.

When it was over, manager Bruce Bochy promised changes were in store.

Geovany Soto delivered a pinch-hit, three-run homer that capped a four-run rally with two outs in the 13th inning and sent the Chicago Cubs to a wild 5-2 victory over the Giants on Thursday.

"We've got to get these bats going," Bochy said. "We've got some guys who are scuffling. So, we'll have to make some changes here."

He singled out leadoff hitter Carlos Torres after he went hitless with four strikeouts in six at-bats. He is 7 for 46 over his last 19 games and can expect some time on the bench.

"Definitely Torres needs a break," Bochy said. "He's lost right now at the plate."

He's not the only one at the moment.

After pounding out 19 runs while sweeping a day-night doubleheader to start this four-game series, they have managed just three while dropping the past two games.

Soto's drive finished an eventful day for the Cubs.

Starter Carlos Zambrano left in the second inning because of soreness in his lower back, then Aramis Ramirez hit a tying home run in the ninth off San Francisco closer Brian Wilson.

The Giants were leading 2-1 after a solo shot by Pablo Sandoval in the top of the 13th off John Grabow (1-0), but the Cubs struck back in the bottom half against Ramon Ramirez (2-1).

Jeff Baker doubled with two outs and scored the tying run on a single by Darwin Barney, who had checked his swing on the previous pitch - an 0-2 slider. Ramirez then intentionally walked Starlin Castro and Soto, batting for Grabow, launched a 3-2 pitch over the left-field wall to give the Cubs the win and the series split.

"I was just trying to get a fastball. See it. Time it. He never threw one," Soto said after hitting the first game-ending homer of his career. "On 3-2, I just try to see the ball, see it up, breaking pitch up. I knew Pena was on deck and a lefty. He left it a little bit up, and I put good wood on it. It feels unbelievable."

Chicago will take that after dropping the day-night doubleheader before pulling out a 2-1 win on Wednesday. The Cubs will try for their first three-game winning streak this season when they open a weekend series against the White Sox on Friday.

The Giants managed just five hits and went 10 1-3 innings without one before Sandoval went deep, wasting another dominant start by Matt Cain.

Even so, they were in line to win this one. But they just couldn't close it out.

"We made a lot of mistakes hitting," Sandoval said. "We have to make adjustments to win the game."

Ramirez, whose pinch-hit single in the ninth gave the Cubs their victory a day earlier, came up big again with his team trailing 1-0 in the ninth and Wilson going for his major league-leading 25th save. He drove a 3-1 pitch out to left for his 299th career homer and 10th this season.

"He's not only a great hitter, but a great clutch hitter," Cubs catcher Koyie Hill said. "The last two days, he's proven that."

And Soto? Well, no one appreciated that homer more than Hill, who caught the entire game.

"We're pretty tight, but we're really tight today," Hill said. "That was nice. That was fun for him to hit that."

The Giants loaded the bases against Grabow in the 12th on walks to Cody Ross and Nate Schierholtz to start the inning and an intentional pass to Miguel Tejada with one out. But they came away with nothing when pinch-hitter Aubrey Huff flied to shallow center and Aaron Rowand lined to right.

Cain pitched four-hit ball over seven scoreless innings for his second straight start. He also struck out six and walked one, just as he did in his previous outing against Cleveland.

For the Cubs, it was an alarming sight to see Zambrano leaving early. He arrived at the ballpark in discomfort, and his day ended when he threw a ball to Eli Whiteside after an RBI single by Tejada.

He started stretching his back, and trainer Mark O'Neal and pitching coach Mark Riggins rushed out with manager Mike Quade following. Marcos Mateo then relieved with the Giants leading Chicago 1-0. That was all for Zambrano, who was booed as he walked off the mound.

Zambrano has struggled at times this season but had been pitching well of late, going at least seven innings in his previous two starts against the White Sox and Kansas City.

Mateo tossed five scoreless innings in relief, striking out six without a walk. Jeff Samardzija, Sean Marshall, James Russell each pitched one.

Carlos Marmol worked the 10th and 11th, and Grabow escaped a bases-loaded jam in the 12th before giving up that home run in the 13th.

"God bless Mateo," Quade said. "Are you kidding me? The whole bullpen, obviously, was great, but he was better than great, to give us that length and that quality. Man, oh, man, what a great job by that kid. Saved us. Helped us win the game. Helped us for tomorrow. Just a huge effort."
