Twenty-two games at the lowest-level full-season affiliate were a sufficient sample size.

The Orioles didn’t need to see any more from outfielder Heston Kjerstad. There was no reason to keep him down any longer.

Kjerstad has been promoted from Single-A Delmarva to high Single-A Aberdeen, with his latest debut set for Tuesday night against Jersey Shore at Ripken Stadium.

The latest reward for a player chosen second overall in the 2020 draft out of the University of Arkansas and unable to play his first professional game until June 10 due to the pandemic, a diagnosis of myocarditis, a setback later and a hamstring injury in March shortly before spring training.

Through it all, Kjerstad somehow maintained a positive attitude and earned a bump to Aberdeen after batting .463/.551/.650 with nine doubles, two home runs, 17 RBIs and 13 walks in 98 plate appearances with the Shorebirds.

Triple-A Norfolk outfielder Johnny Rizer, the Orioles’ seventh-round draft pick in 2019 out of Texas Christian University, underwent hip surgery last week in Philadelphia and is out for the remainder of the season.

The Orioles made the announcement this afternoon.

Rizer appeared in 22 games with the Tides and went 14-for-72 (.194) with five home runs and 12 RBIs in 81 plate appearances. He hit a combined .253/.312/.423 last summer with 15 doubles, three triples, 14 home runs and 53 RBIs in 98 games between Double-A Bowie (83) and Single-A Aberdeen.

Carter Baumler, a fifth-round selection in 2020 out of Dowling Catholic High in Iowa, will miss his next start at Single-A Delmarva due to right shoulder inflammation.

Baumler didn’t begin his professional career until this year after undergoing Tommy John surgery. He’s allowed two earned runs, walked seven batters and struck out 20 in 11 2/3 innings.

Heston Kjerstad was making his second visit to Maryland after flying in from the spring training complex in Sarasota to begin working out with the Single-A Delmarva Shorebirds. Taking his rounds of batting practice and waiting for the Orioles to activate him. In an unfamiliar setting that just seemed right to him.

He noticed it again as he walked to home plate Friday night in his first professional game.

Right where he belonged. Nothing else about it mattered.

“Honestly, just felt alive again being in the box. Just playing some baseball,” he said the following day after going 1-for-4 with an RBI.

“It kind of all comes back to you. You get locked in again for hitting. I felt at home again being able to dig in the box and have my approach, and just take some at-bats.”

Grayson Rodriguez’s year might be over after only 56 innings pitched at Triple-A Norfolk. That’s one of the decisions looming over the Orioles this summer.

They also will hold internal meetings later to figure out whether Rodriguez is a candidate to go to the Arizona Fall League.

They haven’t ruled out the idea.

The Orioles first need to establish a real timeline for his recovery from a Grade 2 strain of his right lat muscle, and that can’t be done so soon after his diagnosis.

Rodriguez is aiming to make his major league debut in September. It’s a big carrot to dangle in front of himself. He’s holding the string.

Heston Kjerstad’s positive attitude is reflected in the way he’s handled the extreme delay in reaching his first professional game. How he used the term “a little bump” today to describe the reasons why it took until now to join an Orioles minor league affiliate.

With at-bats that finally count.

In front of crowds who don't just pass through the gates for free on a sunny day in Sarasota to watch practices.

A diagnosis of myocarditis shortly after the 2020 draft, where the Orioles picked Kjerstad second overall, prevented him from participating in the fall instructional camp. It kept him out of spring training after a setback. And when he finally was cleared this year to participate in a minicamp and in intrasquad competition two months later, he strained his left hamstring chasing a line drive in the outfield.

The weeks of rehabbing led to light workouts and hitting off tees and coach’s tosses, to facing live pitching, to building at-bats in extended spring training, to reporting to Single-A Delmarva this week.

Outfielder Heston Kjerstad, the second-overall draft pick in 2020, finally is able to make his professional debut tonight at Single-A Delmarva – exactly two years after his selection from the University of Arkansas. He’s batting third and serving as the designated hitter.

Kjerstad, 23, was diagnosed with myocarditis after the draft and strained his left hamstring while chasing a line drive from Adley Rutschman in a March 11 intrasquad game in Sarasota. He’s been playing at extended spring training.

The initial prognosis had Kjerstad missing eight to 12 weeks.

The Orioles decided to let Kjerstad - the No. 9 prospect in the organization, according to MLBPipleline.com - skip the Florida Complex League, but he’s on a return-to-play progression with the Shorebirds. He’ll be removed from games in the middle innings per hamstring rehab protocol and standard practices.

Meanwhile, pitcher Cody Sedlock cleared waivers and was assigned to Triple-A Norfolk, so he stays in the organization.

The Orioles have three more games to play in Kansas City before heading to Toronto. I was supposed to be on the current trip, but was switched to Rogers Centre. My first visit since the 2016 wild card game.

More on that later.

The mailbag is allowed in Canada, but I’ll leave it home. Much lighter than its current condition.

Welcome to the latest sequel to the original. You send along questions, I try to answer them, many of you ignore me and rephrase them.

The editing remains minimal. Please don’t contact a lawyer if I remove a word without first issuing a disclaimer about length, style, clarity and brevity.

Ryan Mountcastle is coming off the injured list this afternoon, ensuring that the Orioles make at least one roster move before playing the Rays at Camden Yards.

Maybe more with their bullpen on fumes.

Manager Brandon Hyde didn’t want to use Bryan Baker last night. He’s had Cionel Pérez warm the last four nights, and the left-hander worked two-thirds of an inning in an 8-6, 13-inning win.

The Orioles are carrying 14 pitchers and could whittle the staff again to accommodate Mountcastle, but then they’re back to having multiple relievers down tonight. Otherwise, a position player is headed out the door.

Whatever. They’ll figure it out.

As the Orioles move through the first series of their three-city road trip, hoping the weather allows them to play this afternoon in Oakland, the activity down in Sarasota is picking up in intensity. The daily routine is shifting into another gear.

There’s more to track than the major league club and four full-season affiliates. You just need to do some digging.

The Orioles are playing their first extended spring training game today against the Pirates. Veteran Matt Harvey, signed to a minor league contract on April 8, is making the start.

Harvey won’t be asked to provide much length, of course, since he’s been working out with the team for less than two weeks. But if you’re wondering how far along he is, well, he’s starting an extended spring training game.

Rico Garcia, who missed the 2021 season after undergoing Tommy John surgery, will follow Harvey.
