The Orioles recalled infield prospect Jackson Holliday on Wednesday after a slew of trades before Tuesday’s deadline opened a place on the roster.

On Tuesday evening, The Baltimore Banner first reported that Holliday was on his way to Baltimore, via multiple sources. The indication was that Holliday would be activated, and the 20-year-old has been inserted into the lineup immediately for the series finale Wednesday against the Toronto Blue Jays.

This will be Holliday’s second stint in the majors after the 20-year-old went 2-for-34 in his 10 games in the majors earlier this season. He is being called up again to replace Connor Norby, who was traded to the Marlins on Tuesday.

“I’m definitely more prepared than I was last time,” Holliday said. “Getting that debut out of the way, and all the stuff that comes with that, it’s definitely a little bit easier coming up here the second time and just being relaxed and comfortable with the environment.”

Holliday was scratched from the Triple-A lineup Tuesday after Norby was traded, a source said. Holliday said that when he saw the trades, he figured he might have a chance to return. The infielder, who is expected to play mostly second base, hit .271 with a .908 on-base-plus-slugging percentage at Norfolk this season.

His first stint in the majors didn’t go as planned. In a phone interview with The Baltimore Banner in June, Holliday said the difficult stretch is “all part of learning. I don’t think it’s a bad thing.”

“I think it can always be looked at as a good start to learning how to fail, because this game is the worst sometimes,” he said. “To be able to go up there and fail at a high level, in the long run, I think will be very beneficial for me and my career.”

The Orioles have a need at second base, not just because Norby was dealt, but because infielder Jorge Mateo suffered a dislocated elbow. The Orioles transferred Mateo to the 60-day injured list on Tuesday. Executive vice president and general manager Mike Elias said Mateo’s injury is “significant” and that he will miss quite some time.

As a result, Holliday has a “runway in front of him because of the vacancy that we have at second base right now,” Elias said. Asked whether he considered calling up infield prospect Coby Mayo instead, Elias said “that’s another pathway we could have gone down.”

“Coby Mayo is in the mix,” Elias said. “I think for us here, it was mainly the left-handedness and the readiness that Jackson has at second base. And there’s still avenues for Coby Mayo here in the near future.”

Holliday also missed some time in Triple-A with shoulder soreness and elbow inflammation, but he is healthy once more. Holliday said he’s ready to play nine innings in the field, and he hopes to stick permanently as a big leaguer.

“That was my goal last time,” he said with a chuckle. “That’s definitely my goal this time to be able to come up here and help this team win and hopefully make a long playoff run.”

When Holliday was optioned in April, the Orioles hoped Holliday would get back to his best at the plate — emphasizing his discipline. Holliday struck out 18 times in 36 plate appearances during his short stint. But in the minors, the progress was clear again. He walked almost as many times as he struck out in July for the Tides.

And earlier this month, Elias said he expected Holliday and Mayo to contribute in the majors before the season concluded. Here’s Holliday’s opportunity.

“I’m just going to enjoy it,” Holliday said. “I’m going to enjoy being here and being present. I feel like, last time, it was all a blur.”
