Dodgers manager Dave Roberts expects Treinen (shoulder) to make the NLDS roster, though the right-hander's role and availability are yet to be determined, Mike DiGiovanna of the Los Angeles Times reports.
Treinen hasn't pitched in a game for over a month, so it may be too much to expect him to immediately pitch in high-leverage situations or on back-to-back days. The veteran reliever has thrown only five innings all season, giving up one run and posting a 6:1 K:BB. Treinen is a critical piece of Los Angeles' bullpen when healthy, so it would be a major boost to the team's title chances if he's able to work his way back into shape over a potential deep playoff run. He faced three batters in a simulated game Wednesday and will toss another sim game in the next few days, per Matthew Moreno of DodgerBlue.com.
