SAN FRANCISCO -- The Giants are keeping the ball inside the ballpark, but they're still finding ways to produce runs -- a lot of them, at that.

The Giants entered Tuesday's game against the D-backs tied atop the National League with 252 runs since the All-Star break despite only having 30 home runs in the second half, well behind second-to-last Miami (38), not to mention Major League-leading Oakland (74).

"It might bother me if we weren't scoring runs or getting beat," Giants manager Bruce Bochy said. "But right now we're doing a good job of getting the timely hits and keeping the chain moving. The long ball is nice, it really is, but if you get guys on base, you'll need to get timely hits, and we've been doing that."

The lack of long balls follows a season-long trend, with the Giants dead last in the Major League rankings with 81 home runs. The Majors-leading Yankees (202) have hit more than twice as many out.

"The last thing you want to do is mention it to these guys," Bochy said. "It's hard enough to hit Major League pitching without trying to hit home runs. We just have to keep swinging the way we've been swinging."

Behind the Giants' recent offensive success has been their improved hitting with runners in scoring position, something that dogged San Francisco hitters throughout the first half. The Giants entered the All-Star break ranking second to last in the NL with a .225 average with runners in scoring position, but they have led the NL with a .311 average in those situations since then. In the last two games alone entering Tuesday, the Giants batted .600 (15-for-25) with runners in scoring position, combining for 16 runs in the two comeback wins.

"We've just had better at-bats," Bochy said. "Guys are putting the ball in play a little more often. What was hurting us before were the strikeouts. You have to go compete up there and try to get the ball in play."

Giants add Burriss, two pitchers to roster

SAN FRANCISCO -- The Giants filled out a few more spots on their active roster Tuesday, recalling pitchers Dan Runzler and Dan Otero and purchasing the contract of infielder Emmanuel Burriss from Triple-A Fresno. The Giants designated pitcher Eric Hacker for assignment to make room for Burriss on the 40-man roster.

Burriss hit .214 in 52 games before getting designated for assignment July 28. Having played with the Giants since 2008 and being popular with teammates, Burriss got a warm reception when he arrived in the clubhouse before Tuesday's game against the D-backs.

"It's good to see these guys again," Burriss said. "Sometimes you don't know when the next time you'll see your friends and teammates again, and it's good to be back with these guys in the clubhouse again."

Burriss was hitting .274 in 29 games with Fresno before getting called up again, which he found out about Tuesday morning. He is expected to be used as a utility infielder, specifically as a pinch-runner and defensive replacement.

"He's been playing well," Giants manager Bruce Bochy said. "He went down to Fresno and played hard and played well. He earned this."

The Giants now have 34 players on their active roster, including 17 pitchers. Otero started the season on the Giants' Opening Day roster and begins his third stint with the Giants this season, while Runzler still has yet to appear in a Major League game this season after missing the first two months of the season with a shoulder injury.

"We have a pretty big bullpen now," Bochy said. "I think we used just about everybody yesterday, so they can help."

Bochy still hoping to greater utilize Theriot

SAN FRANCISCO -- With Marco Scutaro thriving at second base, Giants manager Bruce Bochy said he still remains concerned with finding playing time for Ryan Theriot, the Giants' previous starter at the position.

Since being acquired from the Rockies, Scutaro has hit .322 with 33 RBIs in 36 games and has registered multi-hit games in 10 of his last 19 games entering Tuesday. Theriot lost his regular job when Scutaro shifted from third base to second after Pablo Sandoval returned from a hamstring injury, and Theriot has been mostly relegated to pinch-hitting duties as of late.

Bochy, who has left open the option of having Theriot play left field, credited the 32-year-old veteran with remaining upbeat and ready to contribute. Theriot got a rare start last Friday against the Cubs, notching two hits and a walk as well as scoring a run.

"He got the start in Chicago, but it's hard to take Marco out," Bochy said. "He's going to be out there, and I'm going to have to find ways to keep [Theriot] sharp. I will say, though, that he's been doing a nice job of keeping himself ready. He had a nice game in that start against the Cubs."
