SAN DIEGO -- Huston Street's first blemish as the Padres closer cost his team a chance to finish the home portion of the 2012 season on a high note.Street suffered his first blown save of the season as the San Francisco Giants mounted a ninth-inning comeback to win, 7-5, on Sunday in the finale of a three-game series. Having given up a run in each of his two previous outings since returning from the disabled list, Street entered with the Padres ahead 5-4 and got the first batter out on a bunt attempt. Former Padre Xavier Nady came in as a pinch hitter and promptly hit a solo home run to tie the game at 5. Aubrey Huff followed with a single and Hunter Pence hit a two-run homer to center field that put the Giants on top, as San Diego failed to claim the series, which would have been its first series win against San Francisco this season. "I wouldn't say the first one was necessarily a bad pitch," Street said. "It just caught a little more of the plate, and he put a good swing on it. The second one was a bad pitch." Street had converted all 23 of his save opportunities, but said the time off due to a strained calf has not been in a factor since he returned. "If you make too many mistakes sometimes you just can't find it," Street said. "I'm making just as many pitches good pitches as before. I'm just getting beaten on my mistakes, whereas before, I think I was maybe getting a few more breaks. I figure I haven't been as sharp since I came back, but this is the Big Leagues. I was probably as sharp as I'd ever been on any run in the history of my career. You've just got to go back to making pitches, and good things will happen." Padres manager Bud Black concurred with Street's self-assessment, and chose to look at the bigger picture of Street's performance this season, rather than the recent trend. "In regards to Huston, that's his first," Black said of the blown save. "That's a pretty good ratio. I'll take that ratio, with all of the games that he's been in." Sergio Romo shut down the Padres in the ninth to notch his 13th save in 14 chances. Despite the defeat, San Diego finished with a 42-39 record at Petco Park. The team surged to a 25-12 record at home in the second half to claim its seventh winning home record in nine seasons. Logan Forsythe, Yasmani Grandal, and Chase Headley each homered against Giants starter Tim Lincecum to help the Padres build a 5-2 advantage. Everth Cabrera stole four bases, and with 41 on the season, leads the National League. Headley's 113 RBIs also leads the NL in that category. "A little bit of everything today," Black said. "Some good hitting, a lot of homers. A lot of balls up in the strike zone, and that's what happens when you don't make your pitches. Lincecum can say that, and I think our guys can say that." Starter Edinson Volquez left the game due to cramps in his legs in the fifth after throwing one pitch to Aubrey Huff and then stepping off the mound. Following a brief visit with Volquez on the mound, manager Bud Black signaled for Brad Boxberger, and Volquez walked off the field with a team trainer at his side. Volquez allowed two runs on six hits and threw 71 pitches. He struck out four and walked three. "He had cramping in his legs, his calf primarily," Black said. "He tried to fight through it the whole game, but as the game wore on, it became very uncomfortable. It didn't look like it was going to get any better." Boxberger and Brad Brach kept the Giants scoreless through the seventh, before Luke Gregerson and Joe Thatcher allowed two runs in the eighth to pull the Giants within one, 5-4. Lincecum yielded five runs -- four earned -- in six innings. He walked two batters and struck out four. "Obviously, you would've liked to win that one today and go out on a high note," Headley said. "But, that's going to happen, it's part of it. We'll bounce back, but overall we've been really happy with the way we've played the last couple of months."
