SCOTTSDALE, Ariz. -- J.J. Putz played catch Monday and said his back felt better.

The D-backs closer was scratched from his appearance last Friday when he experienced back tightness while warming up. Putz threw from 60 feet for around seven minutes.

"I felt good," he said. "I think it's kind of looking more and more like [it was] a little spasm. We still have some work to do to get it completely gone, but for the most part I think we're going in the right direction."

When asked how relieved he was about how he felt, Putz said, "A lot. Talking with the training staff, I don't think it's anything to be overly concerned about."

Depending on how his back responds Tuesday, Putz's next step will be to throw long toss.

Enright in D-backs' rotation after strong spring

SCOTTSDALE, Ariz. -- A strong spring has won Barry Enright a spot in the Arizona Diamondbacks' starting rotation.

"Enright's in the rotation," D-backs manager Kirk Gibson said as he left the interview room following Monday night's game against the Dodgers. "We'll talk more about it tomorrow."

Entering camp it looked like the D-backs had three set starters in Joe Saunders, Ian Kennedy and Daniel Hudson. Saunders, though, has struggled, and he also missed time due to the flu, and it is not certain whether he has a lock on a rotation spot at this point.

Gibson had previously said only that Kennedy would start on Opening Day and Hudson would start the following game.

With Enright in the rotation, that means there is still one spot up for grabs, or two, if Saunders is not already in it. Armando Galarraga and Aaron Heilman are the other pitchers vying for a spot.

Zach Duke, who was initially in the competition, suffered a broken hand earlier in camp and will miss at least the first month of the regular season.

Enright has a 2.65 ERA in five games this spring.

Worth noting

D-backs right fielder Justin Upton said his right knee was feeling better one day after jamming it while slipping in the outfield. "I knew it was going to be a little sore, but it's nothing to worry about," Upton said. Upton was not in the lineup Monday night against the Dodgers. "He's fine," D-backs manager Kirk Gibson said. "[He] could have played. It's one of those situations where it's a little sore and we've got other guys." ... The D-backs made a number of roster moves Monday. Catcher Konrad Schmidt was optioned to Triple-A Reno, while right-handed pitchers Micah Owings and Brian Sweeney, along with outfielder Wily Mo Pena, were reassigned to Minor League camp. The club also outrighted catcher John Hester to Reno, which removes him from the 40-man roster. There are now 35 players remaining in camp.
