"It's a little bit of a challenge" to face the same lineup again, Tepesch said.
Sunday was a step back from his debut, when he allowed one run in 7 1/3 innings to beat Tampa Bay, but Tepesch said he learned from both outings.
"I feel like I've definitely gotten a little more comfortable since I've been here," Tepesch said. "The first one, I didn't really make as many mistakes. The second one, just leaving the ball over the plate. That was the biggest difference between the two."
