Holliday's kids enjoy Cards' winning ways

Outfielder has done plenty to aid NL Central champs

ST. LOUIS -- Matt Holliday's two young sons -- 5-year-old Jackson and 2-year-old Ethan -- don't know or understand everything that happens during one of their dad's games.

But the two always seem to find out quickly if the Cardinals won or lost that night.

"They don't know everything but they definitely know whether we won or lost," Holliday said. "Because if we win, they get to come in here and play and go down to the batting cage and run around and stuff. They definitely get excited when we win."

Holliday has done nothing but hit since he was traded to the Cardinals on July 24. The right-handed-hitting Holliday is hitting .350 with 13 home runs and 51 RBIs in just 60 games with St. Louis.

But coming to St. Louis meant that Holliday had to uproot his wife Leslee and two sons for the second time in less than a year. After spending five years with the Rockies, Holliday was traded to the A's this past offseason before being dealt again to the Cardinals in July.

While with Oakland, the pending free agent knew that there was a chance he could get traded during the season. As the rumors started to pick up, Holliday tried to explain the situation to his kids.

"I think my 5-year-old knows what's going on," Holliday said. "My 2-year-old just kind of rolls with everything, but my 5-year-old kind of knew that there was a chance I could be traded. I just talked to him like a normal person and he understood it. He's pretty smart for his age and he knows how baseball works and I talked with him about it."

Holliday and his family lived in a hotel across the street from Busch Stadium for almost a month after the trade but recently moved into an apartment complex where several other Cardinals players live. They also enrolled Jackson in a local kindergarten class while Holliday finishes up the season in St. Louis.

While Matt has spent most his time at the ballpark, Leslee and the kids have spent a little time exploring their new, but maybe temporary, city.

"They are enjoying it," Holliday said. "It's been great. They have been out a little bit. They went to the zoo and a couple of things, but he goes to school and they spend a lot of their time here. They have gotten to travel with me some also, but during the season, they don't get a chance to do a whole lot of other things."

The Cardinals are a National League best 40-22 since Holliday joined the team in Philadelphia a little more than two months ago, and all parties involved hope the winning ways continue deep into October.

And so do Holliday's kids, so they can go play in the batting cage.
