Bryce Harper out of Thursday’s lineup vs. the Padres, hoping to return Friday against the Dodgers

Bryce Harper was out of the Phillies lineup for the fourth straight game on Thursday after receiving a platelet-rich plasma injection on Sunday at the Kerlan-Jobe Institute in Los Angeles. Phillies manager Joe Girardi said Harper’s elbow still feels sore, and that the team will take it day by day. The hope is that he’ll be ready to return on Friday for the first game of a three-game series at home against the Dodgers.

Harper hasn’t been doing much baseball activity since he received his injection, but he took some swings on Wednesday and will take more Thursday. Girardi said if Harper’s soreness dissipates by Friday, he’ll be ready to enter a game.

Shortstop Didi Gregorius, who is on the injured list retroactive to May 5 with a left knee sprain, has been making progress, according to Girardi. There’s still no timeline for Gregorius, but Girardi said the shortstop is taking ground balls, hitting, and moving around better than he had been.

Centerfielder Mickey Moniak, who is on the 10-day injured list with a broken right hand, was in extended spring training Thursday and will start a rehab assignment in Clearwater, Fla., on Friday, Girardi said. The Phillies manager says that it will likely still be a while until Moniak joins the big-league club.

“He’s been out a while, so, playing defense, his arm, getting at-bats, it’s been how many weeks, five? So it’ll take a while,” Girardi said.

Phillies starter Zach Eflin is in his seventh big-league season but will be experiencing a first next week as he attends his own arbitration case in Atlanta. Eflin said the case will take place either Monday or Tuesday. Of the Phillies’ three arbitration-eligible players, Eflin is the only one that the team wasn’t able to agree to terms with. The two parties exchanged salary figures in March, which revealed a significant disparity: Eflin is asking for $6.9 million and the Phillies want to pay him $5.15 million.

Eflin said he believes it’s important to be informed, and is excited to see the other side of the industry.

“You can’t really hide anything in court, right? So I’m excited to see our side of how we do things and their side of how they do things, and how they view me as a player and as a person,” Eflin said. “I’ve talked to a lot of people about it. It’s not really the greatest thing to happen, but I come at it from a good mental place, and I am genuinely excited to see what happens there, and see how they view things, and see the true business side of baseball, because I’m curious about that aspect of the game. I’m not really going into it nervous or anything. I’m excited to see what happens.”
