PHOENIX -- Daniel Hudson continues to make progress in his recovery from Tommy John surgery, and the right-hander appears to be a bit ahead of schedule.

Hudson had the surgery last July and was expected to be out until around the All-Star break this year, but it seems possible that he could return closer to the earlier part of July.

Hudson pitched in an extended spring game on Thursday, and he will do so again next Wednesday. It's possible he could then head out on a rehabilitation assignment.

"Just depends on how I bounce back," Hudson said. "It's just day by day at this point. Just see how I feel and go from there. There's really no set schedule, except for when I'm supposed to throw. And if need an extra day, we'll take an extra day, or if I need an extra five days, we'll take an extra five days."

So far, Hudson has not experienced any setbacks or needed extra time, but he's careful not to get ahead of himself.

"Pretty excited, but I've still got a little ways to go," Hudson said. "I just try not to look at it too much and just concentrate on getting better and hopefully getting my command up to par to where I need it to be to be competitive up here and get my arm strength and stamina up."

Hudson, who threw 70 pitches Thursday, is becoming more comfortable with the small tweaks he has made to his mechanics. The changes, he hopes, will take some of the stress off his elbow and shoulder.

"I just feel like I'm getting on top of the ball better and working downhill better," Hudson said.

Hill frustrated with slow healing process of hand

ARI@MIL: Hill's two-run homer pads D-backs' lead

PHOENIX -- With each passing day, D-backs second baseman Aaron Hill loses a little more patience with his left hand.

Hill has been on the disabled list since April 14 after suffering a small fracture on the top of the hand.

The healing process has taken longer than expected, and Hill is set to see a doctor once again early next week. If it has healed enough, Hill will then begin a strengthening program.

"Same old stuff," Hill said when asked for an update. "Yeah it's frustrating, because I want to play. It's what I'm supposed to do. It's what I love to do."

Hill comes to the ballpark every day while the team is at home and watches the games from the dugout. While the D-backs are on the road, he goes by the team's Salt River Fields complex for treatment, which means he gets to spend more time than usual with his family during the summer.

"As I've gotten older, I always try to find the positive in things," Hill said. "I'm getting to see my little girl grow up every day, which is awesome for me, but at the same time, I want to be on the field. I see these guys having a blast, and I'm like, 'Man, I want to be out there.'"

Eaton to get second opinion on elbow

ARI@LAD: Eaton collects two hits against the Dodgers

PHOENIX -- D-backs outfielder Adam Eaton will get a second opinion on his ailing left elbow.

Renowned orthopedic surgeon James Andrews will take a look at Eaton's MRI film on Tuesday. Arizona team physician Michael Lee said Wednesday that the discomfort Eaton felt recently in the elbow was the result of fluid buildup, and that the MRI did not show any structural damage.

If Andrews confirms the diagnosis, Eaton will take the next three weeks off to rest and strengthen the elbow before being reevaluated.

Eaton initially felt the discomfort in March and was shut down at that point. He had recently begun playing in the field and was likely just days away from being activated from the disabled list when he experienced discomfort again.

"It is kind of starting all over again, but you're stepping forward, you're not taking any steps back," Eaton said. "It's a three-week period where I can continue to get stronger and learn from this. As tough as it is and as young as I am, I haven't ever tasted any kind of adversity like this before, so it's definitely going to be a learning process for me to kind of take a step back and learn day-to-day how I can be patient and get healthy."

Snake bites

• Shortstop Willie Bloomquist began an injury rehabilitation assignment with Reno on Friday. Bloomquist was scheduled to play Friday and Saturday, take Sunday off and then play Monday and Tuesday.

"That's as far as I can go with it," D-backs manager Kirk Gibson said about Bloomquist's schedule. "We'll see how he feels."

• The D-backs are heading into a tough part of their schedule, with four games coming up against the American League's top team in the Rangers. Arizona also will travel to St. Louis for a four-game set against the National League's best team.

"I think things are just heating up," Gibson said. "The season is really getting going. We're getting into it now. we'll certainly be tested and have to try and probably rest guys a little more than I have so far."
