ARLINGTON -- Rangers third baseman Isiah Kiner-Falefa was out of the lineup on Sunday against the Rockies for the second straight game with a sore left hamstring muscle.

Kiner-Falefa aggravated the muscle running out a triple in the season opener on Friday night. The Rangers are off on Monday before opening a two-game series against the D-backs on Tuesday at Globe Life Field, and Rangers manager Chris Woodward said he is expecting Kiner-Falefa to be ready by then.

“He’s better,” Woodward said Sunday morning. “I think he’ll be ready after the off-day. It’s more of a precaution, not trying to make something that was not a big deal. Right now, I’m hopeful he’ll be 100 percent after the off-day.”

Kiner-Falefa’s situation allowed Woodward to get Rob Refsnyder into the lineup, with left-hander Kyle Freeland starting for the Rockies. Refsnyder won a job on the 30-man roster in Summer Camp as a right-handed hitter off the bench. He is a career .201/.327/.290 hitter against lefties but was 11-for-38 with one home run and six RBIs in 16 Summer Camp intrasquad games and exhibitions.

“I feel like he was giving us some of the better at-bats in camp, didn’t matter who was throwing,” Woodward said. “But the left-hander represents the best way of getting him in the lineup.”

The Rangers also have Scott Heineman off the bench as a right-handed bat. He was their best hitter in Summer Camp, going 19-for-39 (.487) with six doubles, two triples and two homers in 16 games. Heineman did not appear in either of the first two regular-season games.

“I definitely want to get these guys in the lineup and get them some at-bats,” Woodward said. “They are on this team for a reason. We didn’t put them on this team just to have a name on the lineup card. I believe in these guys. I definitely think those guys can provide a ton of value, especially against tough lefties.”

Rangers adjusting to no fans
Despite the empty stands at Globe Life Field, public address announcer Chuck Morgan and assistant Michael Gruber are pumping in crowd sound into the ballpark, and it is creating a unique atmosphere for the players.

“Yeah, I think with no fans, it's different. It's definitely different,” outfielder Joey Gallo said. “When you're in the heat of the moment anyways there in the season and there's fans, you feel them. But at the same time, you're so locked in that you don't really focus too much on it.

“And the crowd noise that they've been playing is actually, it kind of tricks your mind a little bit when you're on the field, because they're playing in the right situation where there's a big moment. Even when I was hitting [during Saturday’s 3-2 loss], you know, it was 3-1 in the bottom of the ninth with two outs, I felt like pressure from the crowd with that noise.”

Rangers beat
• With a lefty pitching for the Rockies, Nick Solak started in left field, Willie Calhoun was the designated hitter and Shin-Soo Choo was out of the lineup. Woodward said he is trying to get Calhoun’s offense going after he went 2-for-37 in Summer Camp and then missed time with a strained right hip flexor.

• The work goes on for the Rangers' alternate players working across the street at the old ballpark. Ariel Jurado threw two innings of live batting practice on Saturday, and Derek Law, Alex Speas and Juan Nicasio threw one inning each.

• The D-backs are scheduled to go with right-hander Merrill Kelly and left-hander Madison Bumgarner, in order, as their starters in the two-game series against the Rangers that starts Tuesday.
