More from minors, Santander and Hays ailments, and Mancini

The Orioles are perfecting the technique of announcing their latest minor league promotions in huge waves. Not a splash or two.

Shortstop Gunnar Henderson was included yesterday afternoon in a 10-player news drop following the Orioles' 7-4 loss to the Blue Jays. The biggest name of the batch.

Henderson, a second-round pick in the 2019 draft, is making the jump from low Single-A Delmarva to high Single-A Aberdeen.

In case you missed it, the rest reads as follows:

* Outfielder Yusniel Diaz and infielder J.C. Escarra to Triple-A Norfolk, with Diaz finishing his injury rehab assignment.

*Right-hander Kyle Brnovich, infielder Toby Welk and outfielder Kyle Stowers to Double-A Bowie.

*Outfielders Trevor Kehe and Dylan Harris to Aberdeen.

* Infielder Yorkislandy Álvarez and outfielder Lamar Sparks to Delmarva.

There's no pennant race to follow, but the sprint up the organizational ladder is a fascinating watch.

Fans have been wondering about Henderson while the Orioles bumped shortstops Jordan Westburg to Aberdeen and Joey Ortiz to Bowie.

The promotions of pitchers Grayson Rodriguez to Bowie, Kyle Bradish and Kevin Smith to Norfolk, and outfielder Johnny Rizer to the Baysox, also made fans excited - and still curious about Henderson, the organization's No. 5 prospect per MLBPipeline.com and No. 6 per Baseball America.

Henderson didn't play yesterday in the Shorebirds' 3-2 loss to Salem. He's hitless in his last two games, but is batting .312/.369/.574 with 11 doubles, a triple, eight home runs and 39 RBIs in 157 plate appearances.

I got the sense yesterday that his promotion to Aberdeen was coming soon, which I planned on writing today. Well, it was so close to happening that it became official on my drive back home from the game.

Meanwhile, Norfolk's Jahmai Jones has been on an offensive tear since returning from a strained oblique on June 8.

Jones crafted a 10-game hitting streak before going 0-for-2 yesterday with three walks and a run scored. He was 16-for-39 (.410) during the streak with a .489 on-base percentage, .615 slugging percentage, two doubles, two home runs, 12 RBIs, six walks and seven runs.

For the season, Jones was 9-for-18 with runners in scoring position and 4-for-4 on stolen base attempts.

Flashing some tools that intrigued the Orioles when the acquired him from the Angels for Alex Cobb.

The baseball reflex is to demand that the Orioles recall him and hand over second base, but his work isn't restricted to the batting cage.

The Orioles want Jones to keep improving his defense. He's made 11 starts at second base and two in left field, including yesterday's game.

Moving to left was unexpected, since the past shuttling between infield and outfield made Jones a project of sorts at second. That's the position where he's supposed to keep developing. The Orioles have stated that they view him as a second baseman first, with the ability to move to the outfield a bonus.

The Orioles are still trying to gauge when Jones will be ready defensively. Same with Domingo Leyba, who's been playing second and third base.

The offensive stats are half the story.

If you want the full story on Anthony Santander and Austin Hays, it must include how they're playing at less than 100 percent. Santander due to a sore left ankle that he sprained in Miami and Hays due to the strained left hamstring that forced him on the injured list for a second time.

You can tell by the way they're running up the first base line.

Manager Brandon Hyde has been rotating outfielders, with one going to the bench. Santander stayed in right field Saturday afternoon and couldn't make a diving catch on Bo Bichette's fly ball in the ninth inning that fell for a single and tied the game. Hyde already used Hays to pinch-run for DJ Stewart and play left field.

"I think they're doing the best they can," Hyde said. "Santander yesterday felt good, today he was a little sore. And Haysie is a little sore also. So they're trying to play through this and we're trying to manage it and they're doing the best they can."

You have to wonder if it would benefit Santander to put him back on the injured list and bring up an outfielder such as Ryan McKenna, who certainly knows the way to Baltimore. The ankle isn't going to improve if Santander keeps playing.

Santander was 0-for-3 yesterday with a walk and his average is down to .239 with a .657 OPS. He's 5-for-40 with one walk and 14 strikeouts in his last 11 games and has one home run since May 22.

Trey Mancini provided the big highlights yesterday with two home runs to give him 100 in the majors. No Oriole who began his career with the team has reached the milestone in fewer games than Mancini's 531, which I kept trying to explain to a couple of Jim Gentile fanatics who jumped me on Twitter recently for excluding him and demanding that I check my facts.

Here's a fact: "Diamond Jim" didn't begin his career with the Orioles and therefore isn't eligible for the record. It's that simple.

Mancini became the 28th player to hit at least 100 home runs in an Orioles uniform and the first since Chris Davis.

Mancini has nine career multi-homer games, including two this season. He collected only two doubles and one home run this month before yesterday's extra-base bonanza.

"I have not been feeling like myself for on and off I'd say all month," Mancini said. "I've had a few spurts where I felt decent and things, but that's baseball for you. I felt really locked in last month and haven't felt this good. Today, I just made sure to try to just simplify things, make sure I just stay on my back side and keep my front shoulder in there and not flying open."
