Single-A Frederick's Nathan Moreau pitched the second no-hitter of the season for an Orioles minor leaguer in the Keys' 7-0 win over Salem on Wednesday, following Chris Tillman's gem for Norfolk on April 28.

Moreau, 23, was the organization's Pitcher of the Month in May. He was 2-3 with a 2.98 ERA in 16 games (seven starts) for Single-A Delmarva before being promoted to Frederick on the day of the no-hitter.

"I started thinking about it in the fourth [inning]," Moreau said. "There had been a few times this year at Delmarva where I had gone four no-hit innings, and somehow I always messed it up.

"It kind of just got into my head then to take it one inning at a time," he added.

Moreau's accomplishment, which was the first no-hitter for the Keys since Brandon Erbe and two relievers combined to complete the feat in August 2008, happened after an active 24 hours for the young left-hander.

"I found out [Tuesday] after our game [with Single-A Delmarva at West Virginia] that I was coming up," Moreau said. "I got to Salem about 2 o'clock in the afternoon [Wednesday], stopped at the hotel briefly, got my baseball gear and headed to the field."

Moreau credited the Keys' defense, especially the three outfielders, for preserving the no-hitter.

"Kyle Hudson made two great catches in the outfield early in the game," Moreau said. "Ronnie Welty made a catch jumping at the wall in right field, and Xavier Avery tracked down a really good ball right at the wall."
