CHICAGO -- If you're going to the Cubs Convention, you can help some orphaned children in Guatemala, as well as the Boys & Girls Clubs of Chicago.

For the second straight year, Carlos Zambrano's "Big Z Foundation" will have a booth at the convention, which will be held at the Hilton Chicago Jan. 14-16. Anyone making a donation will receive a T-shirt. Fans also will be able to enter a raffle for souvenirs, according to Frank Alvarez, the foundation's administrative director.

Zambrano has a personal motive for his involvement. The father of three girls, the Cubs pitcher is in the process of adopting a boy from Guatemala.

"During the season, I focus on baseball," Zambrano said last March. "In the offseason, I focus on what matters in my life.

"When I was there [in Guatemala], I thanked God for my kids and the people around me, my nephews and cousins," he said. "I thanked God because [my family] has a better life. God blessed us, and I pray to God to bless the children."

Zambrano kicked off his foundation at the 2010 convention with a dinner at Fogo de Chao in Chicago. The goal is to help underprivileged children and families, which brings us back to Guatemala. Zambrano has visited there each of the past two offseasons to work with a group called Hope of Life, or Esperanza de Vida, which is devoted to promoting educational, medical and spiritual development.

In Guatemala, the group sponsors the Paradise Children's Home, which cares for children who are abandoned by their parents, and provides food, clothing, medical attention, and an education.

During his visit in October, Zambrano not only toured a new hospital that's part of Hope of Life's efforts, but he also helped distribute rice, soup and bread to more than 300 people.

During Spring Training, Alvarez said the Big Z Foundation will host a charity softball home run derby in Gilbert, Ariz. No word on whether Zambrano will take a few swings. Check bigzfoundation.com for more information.
