DENVER -- When Amed Rosario was told of his promotion to the Mets on Monday, the first person he called was his sister.
Rosario's sister has been living with him in Las Vegas, and Rosario was on his way to English class when he got the call. But he had to make her promise not to tell anyone else, as he wasn't technically allowed to say anything.
"They told me I couldn't say anything until it was shared with a press release," Rosario said through an interpreter prior to making his Major League debut in Tuesday's 5-4 loss to the Rockies.
The shortstop went 1-for-4, notching his first career hit on an infield single in the eighth inning. Per Statcast™, Rosario's sprint speed was 30.6 feet/second on that hit and he went 4.04 seconds home-to-first, both considered elite.
"It was a tremendous experience just being out there," Rosario said after the game. "I really don't have words to describe it."
The No. 2 overall prospect in the Majors, per MLBPipeline.com, Rosario brings a stellar glove and defensive abilities, something the Mets have sorely lacked this season. He couldn't help with his glove in the decisive ninth inning Tuesday, though, as a DJ LeMahieu infield single caromed off Rosario's glove, after he had tried to cover second base on a steal attempt.
Rosario hit .328/.367/.466 with seven home runs, seven triples, 19 doubles and 19 stolen bases for Triple-A Las Vegas, and his "extra-base power has started to show up more consistently", according to MLBPipeline.com. Mets shortstops have hit just .242/.312/.395 this season, ranking in the bottom third of the National League entering Tuesday.
The pressure hasn't gotten to Rosario though, he said.
"I don't take what's happening off the field onto the field," Rosario said. "I didn't really pay much attention to any of it."
However, Rosario sent a cryptic tweet a few weeks ago, saying he was "on my knees and I just want to propose to Queens -- NY that is," and ready to be promoted. He deleted it shortly after.
"I took it down because I think people really misinterpreted it," Rosario said. "I think they took it not in the way I meant it, I was just trying to have a little fun and be relaxed."
Manager Terry Collins said he wants to ease Rosario into the lineup, but Rosario's play will determine how often he's in the lineup. Collins added that he will likely shuffle playing time at third base between Jose Reyes, Asdrubal Cabrera and others.
"[Rosario] will be the prime guy [at short], but I think he'll benefit from some time off, like anybody else." Collins said. "There's going to be no one guy [at third]."
Though Rosario will likely take much of Reyes' playing time, the two have a friendly relationship. Reyes was once a hyped shortstop prospect, and Rosario said he is thankful to be on the same team as a player he watched growing up.
"I can say 100 percent I just enjoyed the way he played, the sort of camaraderie he carried himself," Rosario said. "He's really been there a lot for me since last year when we were able to start developing that, and it means a lot to me what he gives back to me."
• Reyes is still feeling sore from being hit by a pitch Sunday against the Mariners, but was a lot better Tuesday, Collins said. Reyes was hit in the hand/forearm area by a James Paxton fastball, but managed to avoid any broken bones. Reyes made a pinch-hit appearance in the seventh on Tuesday, reaching first on a passed ball on a strikeout and later scoring a run.
• Collins said he will use new acquisition AJ Ramos as his closer going forward. Ramos had 20 saves for the Marlins this season, and 92 career saves.
