It won't show up in the advanced metrics, but arguably the greatest impact Marlins shortstop Miguel Rojas had on Wednesday night's 3-1 victory over the Phillies wasn't his defensive gem in the eighth but rather his mound meeting in the ninth.

After Jean Segura knocked a first-pitch leadoff double and Yimi García threw back-to-back pitches well out of the zone to Bryce Harper, Rojas visited Miami's closer for a pep talk. The two have known each other for eight years, going back to when they were Double-A roommates in the Dodgers' system.

"Those moments where, more than the pitcher, you know the person, and you know he probably doesn't have his best stuff, you don't see hitters hitting a ball that hard like Segura hit," said Rojas, who was joined by catcher Sandy León. "And then he went 2-0 against Harper there. I didn't want him to crumble in that situation. I want to go out there and tell him that the runner on second base doesn't mean anything at that point, and I just want to make sure that he's regrouped and he knows that we're behind him to make plays and he doesn't have to strike everybody out. Use us as a defense, and just relax and just have a loose hoop."

García did just that, getting back in the count to fan Harper to begin a stretch of 10 straight strikes. Rhys Hoskins reached on an infield hit to put runners at the corners before García threw four consecutive fastballs to strike out Alec Bohm. Andrew Knapp's flyout to the right-center warning track secured García's eighth save in nine opportunities this season. According to Statcast, García's four-seamer (96.8 mph) and slider (91.4 mph) were each more than 1 mph faster than they've averaged this season as he secured his first career four-out save.

Manager Don Mattingly thought it was a good trip by Rojas. Miami trusts its unofficial captain in scenarios like Wednesday night's to settle things down. Like García, Rojas and Mattingly's history also dates back to their time with the Dodgers. He has a sign with the coaches in the dugout when a mound meeting might be needed.

"I always look at the situation of the game," Rojas said. "They know they can use me sometimes when they don't need to go there to say something about mechanics or anything. It's just more of confidence and getting back in counts and stuff like that, and I always check the scoreboard. I always check if we have some more visits left, and I'm not putting the team in a bad position just in case they want to talk to a pitcher and say something mechanically.

"But at that time, I just know that these guys need a little bit more confidence instead of doing something mechanically. ... I've got the freedom to go and just do my thing. Sometimes it's going to go well like tonight, sometimes it doesn't. But at the end of the day, you can't leave anything out there to do, so you just want to do the best to help the team."

Finding spots for Díaz
Isan Díaz got the start at second base with Jazz Chisholm Jr. given a scheduled day off in Thursday night's series finale in Philadelphia. Chisholm, who won the job over Díaz in the spring, returned from a left hamstring strain on Sunday. According to Mattingly, the club doesn't want to push him too fast.

With Chisholm and Díaz both on the active roster, the Marlins will try to find ways to get the latter in the lineup. Díaz started at second on Sunday, with Chisholm moving over to his natural position at short. Díaz has appeared only at second in the Majors, but he did play 14 games at third during the 2018-19 Puerto Rican Winter League. That could be an option moving forward.

"Obviously not as comfortable as we are with [Brian Anderson], but Andy needs days also," Mattingly said. "There's maybe some days that we'd put him over there [at third] and really would be comfortable. He's been taking ground balls, he's played it in winter ball, he's got plenty of arm, his hands are good. We're pretty comfortable with him over there if we had to do it or choose to do it a day here or a day there."
