"They are engaged in the group. These guys don't separate themselves," manager Buck Showalter said of the veterans who weren't pitching, but stayed to watch. "[The prospects] are looking for an ally, they are looking for help. They want to be good."
Harvey, who was shut down last season because of a right flexor mass strain, is a full-go in camp and is certainly on the O's radar. Showalter brought him up unprompted when talking with the media on Saturday afternoon.
"You know what's impressive? You see Hunter Harvey, a 20-year-old guy. He was pretty calm today," Showalter said. "Thought that was good to see. Didn't try to overdo it, overthrow. Pretty good."
Other O's who threw Saturday included: Dane De La Rosa, Brian Matusz, Wesley Wright, Oliver Drake, Steve Johnson, Chaz Roe, Chris Jones, Tyler Wilson, Mike Wright, Tim Berry, Eddie Gamboa and Jason Garcia.
