Arena Football: Conference Championships

1 p.m. and 4 p.m, ESPN

Columbus at Georgia, followed by Chicago at San Jose. I know the anticipation is killing us, but try to save something for the Arena Bowl party.

PGA: John Deere Classic

3 p.m., Channel 13

Tour journeyman D.A. Weibring designed the course on the site of a former Arabian horse-breeding farm. I swear it’s true. And I wish I were creative enough to make up something like that.

NASCAR: Busch Series at Joliet, Ill.

3 p.m., Channel 8

Carl Edwards could break his leg doing a back flip, sit out four races and still have an insurmountable point lead.

MLB: Astros at Cubs

3:30 p.m., FOX

Remember when the Game of the Week started at 1 o’clock and didn’t always involve a team from New York, Chicago, Los Angeles or Boston?

NBA Summer League: Celtics vs. Mavericks

4 p.m., FSNE

All these rookie-dominated summer games take place in Las Vegas. Great way to encourage the new guys to live squeaky-clean lifestyles.

MLB: Blue Jays at Red Sox

7 p.m., NESN

Saturday night games at Fenway are just morally wrong.

MLS: New England at New York

7:30 p.m., Fox Soccer Channel

At least one 9-year-old will watch this game instead of the Sox. I weep for whatever will become of his life.

Auto Racing: IRL at Nashville

7:30 p.m., ESPN

When there’s a chance of a woman driver or an old man starting a shoving match after the race, you’ve got to watch.
