Tulowitzki has been out since the end of May with a left groin injury that required surgery.
Tulowitzki played parts of Game 1 and Game 2 of the series, going 2-for-6 with a double and an RBI. Being slated for nine innings is a sign that Tulowitzki is moving past the tentativeness that has kept him from being activated.
"I don't definitively know what the answer to that question is," manager Jim Tracy said. "But with all the activity that Tulo is getting, the thought process is that at some point in time, we'd like to get him back here and get him involved in games between now and season's end. When exactly that will be? I haven't been told."
