Street had been sidelined since Aug. 11 with a left calf strain and returned with a 21 1/3-inning scoreless streak that spans 22 outings since June 20. Street has only allowed three hits over that stretch.
"It fortifies a bullpen that has pitched pretty well in the second half," manager Bud Black said. "If you look at the overall numbers in the bullpen and some individual performances by guys, a lot of guys have really contributed to our second-half success."
Street's delayed return comes after a setback in the beginning of the month when he experienced soreness in the calf from running sprints. Street had missed 29 games earlier in the season with a strained right lat muscle. He entered Friday with 21 saves on the year, and his next one would be the 200th of his career.
"It's good to get him back in the mix," Black said Friday. "Hopefully we can use him tonight."
