Marte felt tightness in his left hamstring during Sunday's game and was removed after beating out an infield single in the sixth.
"I feel better," Marte said. "I feel pretty good. It's just a little tight. I think I'm going to be ready for Wednesday. I'll just get treatment and do whatever I have to do to be better."
Sherfy throws
Reliever Jimmie Sherfy, who has been out with tightness in his right biceps threw live batting practice Monday, with Rey Fuentes, Christian Walker and Ildemaro Vargas stepping in against him.
"It felt great," said Sherfy who threw about 15 pitches in the bullpen and another 18 to hitters. "No pain."

D-backs manager Torey Lovullo was still unsure whether Sherfy would be healthy enough to be put on the roster for the Wild Card Game. Since making his big league debut in September, Sherfy has not allowed a run in 10 2/3 innings.
Open or closed?
D-backs team president and CEO Derrick Hall said a final decision has not been made about whether the Chase Field roof would be open or closed. Given that the high in Phoenix is forecast for 98 degrees Wednesday, it likely will be shut.
Hall said Major League Baseball makes the ultimate decision on the roof with input from the team.
Roster up in the air
Lovullo said the team is mulling over its roster and was still deciding whether to keep nine or 10 pitchers.
While in Kansas City this past weekend, Lovullo talked with Royals manager Ned Yost about his experience in the 2014 American League Wild Card Game and Yost recommended carrying the extra bench players.
"What I'm planning on doing is walking through some scenarios with the staff and the front office and just having us bounce a lot of different things off of one another to where no situation will catch us by surprise," Lovullo said. "And that will help us understand where there might be a soft spot and we might have a need for an extra pitcher or maybe have a need for an extra position player."
Sellout
The D-backs had held back a limited amount of Wild Card Game tickets for fans who wanted to purchase 2018 season ticket packages, but those tickets have been snatched up as well.
"The demand for this game was through the roof," Hall said.
