Rookie cornerback Kevin “K.J.” Gerard would seem to have an uphill battle to climb to cement a spot with the Ravens, but he helped himself out Tuesday by hauling in two interceptions during Tuesday’s passing camp.

The undrafted free agent out of Northern Arizona is adept at using his 6-foot-1, 187-pound frame to reach high for the football, but he still has a lot to absorb, according to coach John Harbaugh.

“He’s learning where to line up still, so he’s not always in the right spacing,” he said of Gerard. “He’s not always in the right spot. But [defensive backs coach] Mark [Carrier] is doing a great job of bringing him along that way. And he has a natural nose for the ball. He can catch it. You know that he’s making a bunch of plays when the offensive coaches start inquiring about taking a look at him at wide receiver. He’s done a good job.”

Second-year safety Tom Zbikowski also had a good outing, picking off two passes of his own.

And the Ravens worked on a few gadget plays. There was the hook-and-ladder with running back Ray Rice being the recipient of the lateral from a wide receiver, a double reverse involving Rice and wide receiver Kelley Washington, a double reverse and a lateral back to quarterback Joe Flacco, and a pass from John Beck to fellow quarterback Drew Willy.
