It appeared to be a three-run double but Smolinski raced into the gap, fought off the early evening sun and made a tremendous diving catch.
"I just saw it well off the bat," Smolinski said. "I went all out because I wanted to give myself a chance to dive."
A run still scored on what Smolinski turned into a sacrifice fly, but Rangers starter Miles Mikolas struck out Josh Hamilton and left the inning with a 2-1 lead.
Smolinski also had a diving catch on Hamilton's line drive in the second inning.
"He has an idea of how to play the game," manager Ron Washington said. "He is into the game when he is in the outfield. He is a baseball player."
The game started at 6:15 p.m. because of television so Smolinski had to deal with the bright sun shining directly into left field.
"It was bright but luckily for us, we weren't looking directly in the sun," Smolinski said.
