When Greene does see the field, he'll probably be filling in for regular second baseman Jose Altuve or third baseman Matt Dominguez.
Astros interim manager Tony DeFrancesco wants to give Altuve a few days off down the stretch, so Greene could see some time at second. DeFrancesco said Greene would start at second base in Sunday's series finale.
Greene could also play some third base when Dominguez needs a day off and shortstop if Lowrie feels sore. Greene playing in the outfield isn't too likely with the Astros carrying plenty of outfielders, but he has made appearances at all three outfield positions during his career.
"He's a utility guy," DeFrancesco said.
Entering Saturday, Greene was hitting .245 with six homers and eight RBIs in 102 at-bats with the Astros.
