Catching up with the family who sent Christian Yelich a birthday card

MILWAUKEE (CBS 58) -- Some of the Brewers biggest fans are excited for the teams new season.

You might remember Jacob Tomczuk and his family.

Jacob wrote a letter to Christian Yelich last year, wishing the Brewers MVP a 'Happy Birthday.'

The Tomczuk's recently flew to Arizona to catch the team's spring training. 

The family also recorded a video about an act of kindness. They donated to the Brewers Community Foundation.
