PHOENIX -- D-backs reliever David Hernandez was removed from Saturday afternoon's game in the eighth inning with a right ankle contusion after getting hit with a line drive on the right leg.

"It's just a contusion," he said after taking an X-ray. "That's about it. It's just really stiff right now, but I'm sure it will be sore tomorrow. It feels fine."

In a full count with a runner on first and one out, Padres second baseman Alberto Gonzalez hit a pitch back at Hernandez. The ball smacked off Hernandez's leg, and Gonzalez reached with an infield single.

"It just felt like it hit my funny bone," Hernandez said. "My foot just went immediately numb and tingly, and it felt kind of weird. But it feels fine, and I should be ready in a couple of days."

Hernandez said that the ball hit him right above his ankle. He walked off the diamond under his own power.

"It's just a bruise," D-backs manager Kirk Gibson said. "I was afraid to hear it, but we'll see how it feels. They'll do what they do to try and keep as much swelling down as they can. And we'll get him back on the mound as soon as we can."

Acquired in a trade with the Orioles during the offseason, Hernandez has filled the setup role for the D-backs nicely, posting a 2.65 ERA in 62 appearances.

He has recorded 11 saves on the season.

Reliever Paterson continuing to improve

PHOENIX -- Joe Paterson doesn't call it confidence.

"I think it's more being comfortable," he said. "I think I've always had the confidence."

Paterson, the D-backs' right-handed reliever, is feeling very comfortable on the mound as of late, holding his opponents scoreless in 15 straight games since July 16.

"Being comfortable out there has helped, but I don't feel that I've changed much other than being more and more comfortable out there," Paterson said.

The 15-game scoreless streak is his third scoreless streak of at least 10 games this season.

A former 10th-round Draft pick of the Giants in 2007, the 25-year-old, side-arming Paterson was nabbed by the D-backs in the Rule 5 Draft last winter and has performed well as a rookie.

In 30 2/3 innings of work scattered over 53 appearances, he has recorded a 2.64 ERA.

"We've brought him along slow," D-backs manager Kirk Gibson said, "We just kind of gave him certain matchups and tried to give him some successes. And gradually we progressed him to an inning, to the occasional right-hander. He pitched an inning last night."

Part of Paterson's development has been watching other side-arm relievers, like the Giants' Javier Lopez.

"I just look at the guys that kind of throw like me and see how the hitters take pitches versus them, or swing," Paterson said. "They've been doing it for a long time, and why they've been doing it is they have a plan out there. And I'm trying to see that and come up with my own plan."

Hill feeling right at home with new club

PHOENIX -- Aaron Hill doesn't see much of a difference after jumping from the American League to the National League.

"It's still baseball," he said. "See ball, hit ball, right?"

But the 29-year-old D-backs second baseman has noticed one difference.

"You can definitely feel the energy," he said. "It's fun to feel."

After hitting .225 with six home runs and 45 RBIs in 104 games with the Blue Jays before being dealt to the D-backs on Tuesday, Hill has recorded a hit and an RBI in two of his first three games with his new team.

"It's a welcome opportunity," he said. "We have some great guys here that have great reputations, and I've heard a lot of great things about the staff here and obviously the team."

After hitting a career-high 36 home runs in 2009, Hill's power production slipped to 26 homers last season. And while he only has six dingers this season, he figures to step into the D-backs lineup as their regular second baseman.

"They haven't been in the National League very long," D-backs manager Kirk Gibson said about Hill and trade partner John McDonald. "So it's a work in progress."

But Hill believes that results will come if he keeps plugging.

"You have your work routines, you prepare before the game and know what you have to do to win," he said. "There are a lot of ways to win a baseball game."

Worth noting

• D-backs manager Kirk Gibson said on Saturday that right-handed reliever Juan Gutierrez has been shut down again because of a sore elbow, marking the second time he has been shut down this year.

• Left-handed reliever Alberto Castillo is scheduled to throw for Triple-A Reno on Saturday. "He'll have a day off [after Saturday] and then throw again, have a day off and throw again," Gibson said.

• First baseman Xavier Nady, on the disabled list since August 13 with a fractured left hand, "is much further off," Gibson said.
