Near no-hitters
On three instances in Bush's career, he flirted with a no-hitter, taking it beyond seven complete innings.

He pitched $7 1/3$ innings against the Oakland A's until Damian Miller, his future teammate with the Brewers, singled against him. In Milwaukee, Bush's next opportunity came against his former team, Toronto, on June 19, 2008. Lyle Overbay, the man Bush was traded for, led off the eighth inning with a triple to end the bid. In an April 23, 2009 game against the Philadelphia Phillies, he once again took the no-hit bid $7 1/3$ innings before giving up a home run to Matt Stairs.
