TORONTO -- Though declared out for the rest of the regular season earlier this month, there remained a chance Nathan Eovaldi could make it back by the ALDS, should the Yankees make it that far.

That possibility was significantly "lessened," Joe Girardi said Monday, after the righthander, out since Sept. 8 with right elbow inflammation, suffered a slight setback. Eovaldi was supposed to begin his throwing program Monday but that will be delayed at least a week as he is still experiencing some discomfort.

"When he pushes hard on it, he feels it then," GM Brian Cashman said, adding that all the remaining tests done on the elbow checked out fine.

Still, with where the Yankees are in the season, Cashman said the thought of simply shutting down Eovaldi, who is 14-3 with a 4.20 ERA, for the rest of 2015 is "certainly going to be in play."

"We'll see," Cashman said. "The only thing we're interested in right now is making sure he's right before we take that next step. And if he's not right we won't take that step."

Quick return for Tanaka

Girardi said Masahiro Tanaka, who is being skipped Wednesday because of a Grade 1 hamstring injury, should be reinserted into the rotation sometime next week. Cashman said exactly when will be determined by where the Yankees are in the playoff race, meaning lining the righthander up to start the one-game wild-card contest should the division title be a long shot or out of reach. "Those things will definitely be a part of the conversation," Cashman said.

Severino gets Jays thrice

Luis Severino will make his ninth career start Tuesday, with three of them coming against Toronto. "I think if you ask any pitcher, they would rather not face a team three times in one month," Girardi said. Severino allowed three runs in six innings Aug. 16, hurt when Carlos Beltran lost a ball in the sun, and six runs over 22/3 innings Sept. 11.

"Last time I was up the whole time," Severino said. "If you make good pitches you're going to get good results."
