''I felt like I played quite well, not spectacular, but very consistent,'' Garcia said.
Garcia opened with six birdies while Ormsby, who arrived at the Eichenried course on the back of three missed cuts, returned to fine form with eight.
''I had a fast start out there, turned in 30 on the front nine, and then kind of kept it going on the back,'' the Australian said.
Detry had a bogey on the first hole but recovered with six birdies and an eagle.
Defending champion Henrik Stenson (67) was among 12 players tied for sixth.
