Orioles top pitching prospect Dylan Bundy continued his domination of the South Atlantic League on Sunday afternoon with five shutout innings of one-hit ball against the Hagerstown Suns, continuing to fuel talk about whether he's ready to move up to high Class-A ball.

Bundy, who struck out four and walked none Sunday, retired the first 12 hitters he faced before allowing a double to Mattew Skole to lead off the fifth inning.

Skole moved to third on a sacrifice bunt, and Bundy also hit a batter that inning, but he was able to get out of the inning without allowing a run.

Bundy, the No. 4 overall pick in last year's June draft, still hasn't allowed an earned run as a professional -- he allowed one unearned run in each of his previous two starts -- and has allowed just five hits in 30 innings, striking out 40 and walking two.

Opposing hitters are batting .043 off Bundy and he still hasn't allowed a hit with a runner on base.
