Then he lost the no-no and a 3-0 lead over the next four hitters.
"I could care less about a no-hitter," he said. "I want wins tagged next to my name. The game is hard enough as it is to grind out year after year. ... I've got three wins at this point in the season. It's frustrating."
The Reds ended up scoring a run in the bottom of eighth on Drew Stubbs' home run and beating the Brewers 4-3.
Arroyo allowed only one baserunner through seven innings and had retired 20 in a row when he walked George Kottaras with one out in the eighth. Tyler Green then sliced a double down the right-field line, and pinch-hitter Cory Hart doubled in two runs.
Arroyo got pinch-hitter Rickie Weeks, but Norichika Aoki singled in Hart to tie it, knocking Arroyo out of the game -- and making him ineligible for the victory he so desperately wanted.
Arroyo was aware of the no-hitter by the fifth.
"You could hear the crowd getting louder," Arroyo said. "It was hard not to notice."
Arroyo is superstitious.
"I've got a 100 of them," he said. "But none involve having no hits in the sixth, seventh inning. Winning the ballgame is most important thing. It's not like it's been easy for me to tag wins to the side of my name."
