Keselowski, who won the race last year, said he circled his calendar to make note of the run at the Iowa track, which is sponsored by John Deere.
"It became a really important race for me," Keselowski said. "There was going to be only one inaugural winner of that race and I wanted to be that driver."
Keselowski fought off Kyle Busch to take the checkered flag, and hopes to do so again this year. The race is being held at the Speedway on July 31.
For his part, Busch said he hasn't forgotten last year's loss and hopes to avenge it this weekend. Of the 16 races he's been in this year, Busch has won eight. He is only three wins away from beating the season-high mark, which he currently shares with Sam Ard. The latter set the record in 1983 and Busch tied him two years ago.
