On Friday, Veras entered in the ninth with the Cubs trailing the Brewers, 4-3. He struck out two of the four batters he faced, but Chicago wasn't able to rally for the win.
"Those are situations he's pitched in before; it's not foreign to him," Renteria said of late-inning work. "We want him to continue to build as much confidence as he possibly can and [Friday] was an opportunity that we had for him, and we used him."
Veras was the closer at the start of the season, but he lost that job after blowing a two-run lead April 11 against St. Louis. Could Veras be the closer again?
"In the end, as it evolves and how he continues to perform will dictate how we move forward," Renteria said.
