Cincinnati's 26-year-old center fielder was 0-for-5 at the plate Saturday, but he made an outstanding defensive play among his three putouts during the Reds' 11-7 loss to the D-backs at Great American Ball Park.
LaMarre sprinted to his left for a terrific diving catch of Chris Owings' line drive for the second out of the sixth inning.
"Defense is something I try to take pride in every day," LaMarre said. "I try to play with recklessness."
LaMarre came to Cincinnati with a reputation for defense. He was named the organization's best defensive player from 2010-13.
"He was real good out there," Reds manager Bryan Price said. "He made a couple really nice catches. He understands the position extremely well. We talked during the game and we told him, 'You're the center fielder; play center field. Don't defer to the corner outfielders."
Although hitless Saturday, LaMarre said he became more comfortable with each plate appearance.
"I knew going into that first at-bat that I would have a lot of nerves," LaMarre said.
