SCOTTSDALE, Ariz. -- Wade Miley starts off the day very vigilant.
But invariably once stretching starts, or maybe the day's drills get under way, he forgets and then suddenly there's a big chewing-gum bubble on his hat courtesy of closer/prankster J.J. Putz.
Tuesday, for the first time Miley actually caught Putz in the act and was able to knock it off.
"The best thing is everyone in here is a part of it," Miley said looking around the clubhouse. "They all block shadows so I can't see his shadow putting it on there and next thing I know, bam, it's on there."
It's a tradition of sorts that began after Miley got called up from Triple-A last year and seemed to happen every game.
"The worst was when he set it up for me to go out there and catch the [ceremonial] first pitch," Miley said. "And I'm walking out there and I look up on the scoreboard and there's a huge piece of bubblegum on my hat. That was the most embarrassing one. My grandma has pictures of that in my room. She printed pictures off and they're framed."
Miley has begun to plot his revenge.
"I got him one time, but he claimed he knew it was on there, so I don't know, I guess that's not official then," Miley said. "I'm going to get him. I gotta do something. I'm not going to do the bubblegum on that hat. I'm going to do something else."
Rookies, though, have to be careful when playing pranks on veterans.
"It's hard because I've got two months in and he's got eight years, but it's getting serious now," Miley said, his smile making it clear he really wasn't serious. "You've got to put your foot down at some point, right?"
Hudson explains retaliation comments
SCOTTSDALE, Ariz. -- Daniel Hudson stood by the comments he made to KTAR 620 AM on Monday, but the D-backs right-hander sought to clarify them a bit Tuesday.
Hudson was asked about the number of times outfielder Justin Upton had been hit last year.
"If it's a starting pitcher, remember, he's got to hit," Hudson told the station. "They either have to hit their spots, or expect something in return."
Tuesday, Hudson wanted to make it clear that he did not mean that as a warning to the rest of the National League -- well, at least not an official one.
"It's just something we paid attention to last year, but at the same time we were trying to make a playoff push so we were trying to be smart about it," Hudson said about the fact D-backs pitchers did not often retaliate when Upton was hit. "But from the get-go this year, we're more aware of it, so if it happens, consequences shall, or shall not, be made."
Upton was hit 19 times last year, most in the NL.
"Obviously everyone knows he's our best hitter and kind of tried to take him out of the game as much as possible," Hudson said. "The scouting report may be to throw him inside, pound him inside, but it comes to a point where you either hit your spot or you don't, and when it becomes a problem is when you do it more than once in a game, more than once in a series. Then it becomes a problem. I said what I said and I stand by it, but like I said, it got perceived a little bit different than I actually said it."
Kennedy open to multiyear contract talks
SCOTTSDALE, Ariz. -- Ian Kennedy will be eligible for salary arbitration following this season and the right-hander said he would certainly listen if the D-backs wanted to talk to him about a multiyear contract.
"Obviously I would entertain hearing it," he said. "I think anybody would."
Kennedy said that as far as he knows, his agent, Scott Boras, has not had any multiyear discussions with the D-backs.
Kennedy was acquired by the D-backs in a three-team trade prior to the 2010 season. In two full seasons in Arizona, he is 30-14 with a 3.31 ERA. Last year, he finished fourth in the National League Cy Young Award voting after going 21-4 with a 2.88 ERA.
Teams sometimes try to lock up their younger players before they hit arbitration. The risk for the club is that the player doesn't perform as expected, whereas the benefit is if he does, they often get him at a reduced cost.
For players, it's a balancing act between accepting a little less in terms of money for greater security.
"It's always hard because you see a lot of contracts like that don't make sense for players," Kennedy said. "For them it does. I know it's hard for someone to pass up millions of dollars guaranteed. I believe as a player you have the right to negotiate every year if you want to. It all depends on if it makes sense for teams and for players."
Kennedy recently discussed contracts with new teammate Trevor Cahill, who last year signed a five-year, $30.5 million contract that includes a pair of club option years.
"He said for him he couldn't pass it up," Kennedy said. "Sometimes it works out for the team, sometimes it works out for the player. You never know."
Skaggs, Bauer to pitch in spring opener
SCOTTSDALE, Ariz. -- The D-backs' first game of the Cactus League will feature a pair of the club's best pitching prospects.
The D-backs open the spring with split-squad games against the Rockies at Salt River Fields and against the Giants at Scottsdale Stadium.
Left-hander Tyler Skaggs will start in the game against the Rockies, and he will be followed to the mound by Trevor Bauer.
Skaggs was acquired as the centerpiece in the deal that sent Dan Haren to the Angels prior to the Trade Deadline in 2010. Bauer, meanwhile, was the No. 3 overall pick in the 2011 First-Year Player Draft.
Josh Collmenter will get the start in the game against the Giants.
