Tomlinson, 25, made his first outfield appearance in six professional seasons. He caught two fly balls hit by Dexter Fowler, hesitating before he rushed in to catch the first one. Though Tomlinson received a crash course in playing center field during instructional league last fall, he spent no time at the outfield corners.
Still, the experience was useful.
"I was able to get a little bit of comfortability in case something like this happened," Tomlinson said.
Tomlinson insisted he wasn't overly surprised to receive his outfield assignment.
"I figured this would come up," Tomlinson said. "It's still baseball and that's what I've done my whole life."
