WASHINGTON -- The D-backs' game with the Nationals on Thursday will be broadcast live on FOX Sports Arizona.

The game can also be seen live for free on MLB.TV, as it will be featured as MLB.com's Free Game of the Day, sponsored by T-Mobile.

The game was not initially scheduled to be aired, but the station decided to pick it up with Arizona lefty Patrick Corbin going for a perfect 10-0 start to the year, opposite Washington's Stephen Strasburg.

Steve Berthiaume and Bob Brenly will call the game, which begins at 1:05 p.m. MST.

"We know D-backs fans will want to see this game featuring two of the best pitchers in baseball," FOX Sports Arizona general manager Brian Hogan said in a statement.

D-backs closer Bell: Issue recognized, solved

MIA@ARI: Bell strikes out LoMo to earn his 13th save

WASHINGTON -- D-backs closer Heath Bell said he has worked out the mechanical issue that has led to a rash of home runs allowed.

Bell has allowed seven runs in four innings over his last five outings. The right-hander allowed a homer in each of those appearances.

"I fixed it last Sunday," Bell said. "It was really something very simple. It's one of those things sometimes a coach sees you do something that you don't feel yourself doing or see yourself doing. Then you correct it. And as soon as you do, it's like, 'Why wasn't I doing this before?'"

After he allowed a walk and a home run to the only two batters he faced Saturday, Bell spoke the next day with pitching coach Charles Nagy, and the pair looked at video together.

Nagy asked Bell to make a small change, and Sunday they worked on implementing it during a side session.

"Threw five pitches and I was like consistent with it," Bell said. "It's just something that I wasn't aware of. It's just what happens over the course of a season."

Gibson and Co. striving to solve Cahill's struggles

WASHINGTON -- The search for the solution to Trevor Cahill's struggles continued Wednesday, with D-backs manager Kirk Gibson looking at video of the right-hander's tough start Tuesday night against the Nationals.

"You look at the game and evaluate and try to get him in the right frame of mind to execute his pitches for his next start, whenever that is," Gibson said. "Just not consistent throwing the ball where he wants to throw it. He gets 0-2, he makes bad pitches, he walks the No. 8 hitter."

After the game -- in which he allowed six runs on eight hits in five innings -- Cahill said he didn't feel like he was consistent with his delivery.

Catcher Miguel Montero said it didn't look like Cahill's arm angle was consistent -- something that Gibson noticed as well.

"You can see it," Gibson said. "I'm not going to go any deeper into that, but something tells me he needs to simplify things. That's what happens when you struggle -- everybody overthinks things. When you can simplify things and think less, you just execute better."

Cahill is 0-4 with a 9.30 ERA in five starts during the month of June, and he is next scheduled to pitch Sunday against the Braves in Atlanta.

"He's got good stuff; we all know that," Gibson said. "We have to get him straightened out. We'll probably talk to him tomorrow and see where he's at and go from there."

Snake bites

• Injured closer J.J. Putz came through back-to-back rehab outings Monday and Tuesday for Triple-A Reno without any problems, and he is expected to take a couple of days off before joining the D-backs in Atlanta, where he'll be activated.

• Second baseman Aaron Hill was 2-for-4 on Tuesday night, his first big league action since going on the disabled list April 15.

"He was on base a lot, swung the bat well," Gibson said. "We've missed him. It's going to take us some time to adjust and figure out the right place to put him, and for me how to play him, how many days in a row I want to play him. Keep him healthy, just keep him kind of building his strength back, get him back up to game speed."

• Injured third baseman Eric Chavez played back-to-back games for Reno, and he was scheduled to take Tuesday off before playing in back-to-back games again.

"We'll just kind of see where he's at after he plays in his next two-game stint," Gibson said.
