Class AA Harrisburg catcher Derek Norris, widely regarded as one of the Nationals best three minor league prospects, will miss the minimum number of games after being placed on the seven-day minor league disabled list yesterday, Nationals director of player development Doug Harris said.

On Monday night, before Harrisburg’s game was rained out, Norris rolled his ankle on first base after running out a groundball. Immediately, the Nationals knew the injury was not serious. “If there was a way to not put him on the seven-day DL, we would,” Harris said.

But after team officials discussed it, they decided they couldn’t leave Harrisburg with one less catcher for three or four days as Norris healed. If he was an outfielder, Harris said, Norris probably would not have been placed on the disabled list.

I also asked Harris what or who had stood out to him in the first six or so games of the minor league season. The first name he mentioned was Harrisburg right-handed starting pitcher Brad Meyers, who struck out nine batters and walked none in five scoreless innings in his first start of the season. “Great life on his fastball,” Harris said. Meyers, 25 was a fifth-round draft choice in 2007.

Harris also mentioned Cole Kimball, Collin Balester and Craig Stammen from Class AAA Syracuse. He said the Nationals have been pleased with their minor league pitching in general.
