Williams suffers broken right foot

SCOTTSDALE, Ariz. -- D-backs third-base coach Matt Williams has a broken right foot and will miss at least the next two weeks and possibly the first week of the regular season.

Williams suffered the injury Monday while doing a soft-toss drill with his college-aged son, Jacob. It is the third time Williams has broken that same bone. He did so in 1995 and 2000 during his playing career, which caused doctors to insert a metal plate in the foot.

"I hope he's still a fast healer," D-backs manager Kirk Gibson said. "Hopefully, he'll be back before Opening Day, but we don't know that."

The timing of the injury is unfortunate as Williams is heading into his first season as third-base coach in the big leagues.

"Spring Training games are probably important for him in getting to know arms, knowing our baserunners and working with Gibby on signals, which will be important when the season starts," general manager Kevin Towers said.

The D-backs have used different third-base coaches in Williams' place, including bullpen coach Glenn Sherlock and Triple-A Reno manager Brett Butler.

If Williams is not available by the April 1 opener against the Rockies, the D-backs have a number of different options. They could use a coach who is currently on the staff, like bench coach Alan Trammell, and have Williams serve as bench coach.

Or they could decide to use Butler. The issue with adding another coach is that Williams would either have to watch games from the clubhouse or the D-backs would need permission from the opposing team to have an extra coach on the bench.

Williams is still doing his other duties, working with infielders the last couple of days while wearing a walking boot.

Zavada faces hitters for first time this spring

SCOTTSDALE, Ariz. -- Clay Zavada faced hitters for the first time since undergoing Tommy John surgery last May in a simulated game at Salt River Fields at Talking Stick on Wednesday.

Zavada threw 20 pitches facing left-handed hitters Kelly Johnson, Stephen Drew and Russell Branyan.

"It went well," Zavada said afterward. "I didn't strike everybody out or anything like that, but I was happy. I was down in the zone and I got to face some really good hitters."

D-backs manager Kirk Gibson watched Zavada and said, "He looked good. He threw the ball good."

Zavada had a miserable spring in 2010 and an even worse first month of the season at Triple-A Reno before his elbow injury was diagnosed.

"My arm felt great today -- that's what I'm going to take away from this," he said. "Just overall, it's good to be back out there. I wanted to stay out there because I was having so much fun. It's a lot different than the last time I faced hitters in Reno."

No timetable has been set up for Zavada to pitch in a Cactus League game.
