PHOENIX -- Left fielder Xavier Nady estimated Friday that his left hamstring is 90 percent healed and insisted that he could play if necessary. But, predictably, manager Bruce Bochy maintained caution and said that he'll wait at least another day or two before returning Nady to the lineup.

Nady, who hasn't played since he strained his hamstring Sept. 5, would be potentially useful in this series against the Arizona Diamondbacks. The right-handed batter, who was 4-for-12 when he was sidelined, would have fit nicely in the lineup against Arizona, which is starting left-handed pitchers in each of the three games this weekend.

"He's so close to being able to go," said Bochy, who nevertheless was reluctant to start Nady and risk exposing the 33-year-old to a physical setback. Bochy pointed out that Nady hadn't taken fly balls yet, but could be available to pinch-hit Friday.

Nady reluctantly exercised patience.

"Obviously, you want to play this game as healthy as possible," he said. "But I understand that it's not going to be 100 percent out of the gate. I just have to be smart in certain situations and Boch knows it."

Liner off foot won't keep Vogelsong out

PHOENIX -- Ryan Vogelsong tested his right foot in his between-starts bullpen session Friday and was deemed fit to take his regular turn in the pitching rotation in Sunday's series finale here.

"I don't see any issue with him making his start," manager Bruce Bochy said.

Vogelsong was hit by Tyler Colvin's second-inning line drive on his foot Monday at Colorado, where the right-hander yielded four runs in five innings and absorbed the decision in San Francisco's 6-5 loss. Vogelsong has recorded a 9.57 ERA in his last six starts after posting a 2.27 figure in his first 21 outings.

Giants take over Major League triples lead

PHOENIX -- It's not the most significant development in the baseball world, but it does reflect something positive: The Giants pulled into the Major League lead in triples while winning the final two games of their previous series at Colorado.

Angel Pagan, Gregor Blanco and Hunter Pence each tripled to hike San Francisco's total to 50, eclipsing Colorado's 47. The American League leader in triples is Detroit, with 36. So if the Giants can fend off Colorado in this category -- no other National League club entered Friday with more than 40 triples -- they'll lead the Majors in three-base hits for the first time since 1973.

Though Pagan began Friday with a team-high 12 triples, tying Willie Mays (1960) and Steve Finley (2006) for the franchise's highest single-season total since it moved to San Francisco in 1958, the Giants' sources have been balanced. Melky Cabrera hit 10 triples before departing; Joaquin Arias, Brandon Belt and Blanco each have five.

Similarly, the 1973 club received 10 triples apiece from the equally fleet Gary Matthews and Garry Maddox, who were both playing their first full Major League seasons. Tito Fuentes had five triples, while fellow regulars Dave Rader, Chris Speier and Bobby Bonds totaled four each. Though Bonds' total might seem surprisingly low, that happened to be the season in which he hit a career-high 39 homers.

Reserves Gary Thomasson and Mike Phillips tripled four times each. Phillips collected his in only 112 plate appearances. And future Hall of Famer Willie McCovey, sore knees and all, legged out three triples.
