Gibson confirms Trumbo's stress fracture prognosis

PHOENIX -- D-backs manager Kirk Gibson corroborated the prognosis of left fielder Mark Trumbo, specifying that the length of his absence due to a stress fracture in his left foot might be even longer than the six weeks Trumbo predicted.

"The summary I got on it confirmed six to eight weeks probably," Gibson said. "He's got a boot on there with something on it called a bone enhancer that sends some stimulation down there. I know that he had [an injury] previously on the other foot and that was lengthy. We don't expect that to be that lengthy."

In 2011, when Trumbo was with the Angels, he suffered a break of the tarsal navicular near the rear of his right foot, a much more serious injury. The results this week of an MRI and CT scan on Trumbo's left foot revealed a stress fracture of the third metatarsal bone at the top of the foot.

"That one is a serious, serious thing," Trumbo said about the previous injury. "That's a career-ender under certain circumstances. It's not a fun one. This is a fairly common injury with runners, you can look it up online. It's pretty cut and dried what you have to do to come back."

The D-backs placed the left fielder, who leads the team with seven homers and 19 RBIs, on the 15-day disabled list on Thursday before the final game of a four-game series against the Cubs in Chicago.

Trumbo began feeling the effects of the injury during Monday night's game at Wrigley Field and an MRI revealed the extent of the damage. He saw D-backs orthopedic specialist Dr. Michael Lee, who administered the CT scan on Friday, and expects to see a couple of other specialists in the upcoming days.

Trumbo suffered the injury to his right foot during his rookie season and played more than a month on it before he was disabled near the end of September. He returned to play 144 games in 2012.

Trumbo was obtained by the D-backs this past offseason in a deal with the Angels that sent pitcher Tyler Skaggs to Los Angeles. It was anticipated that he would bolster the lineup and augment power displayed by first baseman Paul Goldschmidt. Despite hitting .210 with a .264 on-base percentage in 21 games, Trumbo was already doing just that.

D-backs unveil Children's Museum exhibit, give $100K

PHOENIX -- The D-backs unveiled their Move It! exhibit at the downtown Children's Museum of Phoenix on Saturday and the Arizona Diamondbacks Foundation donated $100,000 to the museum as part of its Grand Slam Grants program.

The ribbon cutting ceremony for the exhibit, which provides children with a place to learn through play and movement, was attended by club president Derrick Hall and D-backs reliever J.J. Putz.

"Through our foundation, we're very proud of the impact we've been able to have with our grants and Grand Slam Awards and we give away so many of those each year," Hall said. "[We donate] anywhere from $50,000 to $75,000 with the grants and then our Grand Slams, where we give four or five each year of around $100,000 each.

"We can make quite an impact at places like the Children's Museum, where we now have this Move It! exhibit which kids can enjoy throughout the year. From an exploratory or educational standpoint, this is a perfect place for us to be attached to because of their focus on youths and because they're our neighbor right up the street [from Chase Field.]"

The exhibit provides innovative design and the use of repurposed materials invites active exploration, imaginative play and thought-provoking discoveries as well as physical activity of both fine and gross motor skills. Elements of the exhibit include the Willie Maze, Diamond, Dugout, Snake and the Bases that incorporate baseball themed items, the D-backs said in a press release.

"The Children's Museum is an amazing place," Putz said. "They just have so much room for activities and they've got some really creative exhibits. The kids love to come here and run around and go crazy but I think they're actually learning something while they're running around."
