The Gill family is batty for baseball, but their rec room is stuck in the minors. The Mega Dens team envisions a swanky clubhouse with big-league touches like an artsy grid of actual baseballs, a wine rack made from bats, and their favorite team's colors setting the tone. Paul and Turner stain new pine four different colors to simulate mismatched two walls of barn wood, and Lisa the tool rookie is in charge of the install. Brothers Turner and Ethan go head-to-head in a painting competition, but it's Mikey who loses when most of the paint ends up on him. Joey and Anitra demonstrate an inexpensive and quick way to create interest with DIY judge's paneling, and a narrow mudroom becomes the family's new bar. MLB Network analyst and former big leaguer Eric Byrnes takes the family on a tour of Atlanta's Turner Field, and some pieces of the ballpark actually come home with the crew: scrollwork seat ends become the corbels that support the new bar top, and Eric steals one last base as a special souvenir for this MLB makeover that is sure to hit a grand slam with the Gills.
