The Orioles had a surplus of quality minor league infield prospects and they were still seeking a pitcher to slot into their 2023 big league rotation, especially a lefty. Today those two added up to a deal where the Orioles acquired lefty starter Cole Irvin and Single-A right-hander Kyle Virbitsky from the Athletics in exchange for minor league shortstop Darell Hernaiz.

In the deal, the O’s gave up a top 30 prospect – Hernaiz was No. 16 via MLBPipeline.com – but they also acquired a pitcher that has averaged 180 innings the last two years with an ERA of 4.11. He has made 62 starts the last two seasons, but still has four years of team control remaining and will not even be arbitration eligible until after the coming 2023 season.

Here are a few more notes on the new O’s lefty after the deal was officially announced by the Orioles this afternoon:

* Irvin went 9-13 with a 3.93 ERA last year over 181 innings. He recorded strong numbers in WHIP (1.160) and walk rate (1.8) while making 15 quality starts. He produced 1.4 fWAR to rank second among A’s pitchers.

* An A’s beat writer tweeted today that Irvin was likely going to be Oakland’s opening day starting pitcher this year.

The Orioles succeeded today in finding a starting pitcher for their unsettled rotation, consummating a trade after failing to reach terms with a free agent.

Left-hander Cole Irvin and minor league pitcher Kyle Virbitsky were acquired from the Athletics for Single-A infielder Darell Hernaiz. Lefty reliever Darwinzon Hernandez was designated for assignment to make room for Irvin on the 40-man roster.

Irvin, who turns 29 on Tuesday, could be the only left-hander in the Orioles rotation on opening day with John Means recovering from Tommy John surgery and DL Hall a consideration for the bullpen. He’s made 62 starts over the past two seasons and posted a cumulative 4.11 ERA in 359 1/3 innings, with 1.8 walks and 6.4 strikeouts per nine frames in 2022.

The Orioles get more than durability with Irvin, who registered a career-low 3.98 ERA and 1.160 WHIP last year in 30 starts. He’s under team control through 2026.

The Phillies were the third team to draft Irvin, landing him in the fifth round in 2016 out of the University of Oregon. The Athletics acquired him in a cash deal on Jan. 30, 2021.

The noticeable increase in international spending by the Orioles included six-figure bonuses for Edwin Amparo and Leandro Arias. They have more in common than cash. Amparo ($650,000) and Arias ($600,000) are Dominican-born shortstops. They're teenagers and switch-hitters, with the latter ranked as the No. 46 prospect in MLBPipeline.com's Top 50 list. Here's what the club said about both players in Saturday's news release announcing the 24 signings: Arias, 16, is a shortstop prospect...

The Orioles bolted to an early lead tonight and lost their offensive touch. Their starter ran up a high pitch count that threatened his removal by the middle innings. Manager Brandon Hyde tries to find new methods to pull the Orioles out of their old ways, whether it's with his personnel or how he gets them to the ballpark. Tonight's lineup underwent drastic changes based more on health than a hunch. What's it going to take to form a congratulatory line after the final out rather than...

Baseball America has published its updated top 30 prospects list for the Orioles, and first-round pick Colton Cowser ranks fifth while beginning his professional career in the Rookie-level Florida Complex League. Heston Kjerstad, last year's first-rounder, hasn't appeared in a single game after being diagnosed with myocarditis, but he's sixth. This year's second-round pick, infielder Connor Norby, is 10th. A big jump was made by Double-A Bowie shortstop Joey Ortiz, who's 12th in the system...

The Orioles hit four solo homers and behind right-hander Jorge López beat the Yankees 7-1 Monday night. But last night New York got six runs in 2 1/3 off Alexander Wells as they routed the Orioles 13-1. So the rubber match is tonight. For the Orioles, this game will decide both if they win this series and have a winning, 4-3 road trip. The pitching matchup features two pitchers on a roll as right-hander Matt Harvey (6-10, 6.20 ERA) faces right-hander Jameson Taillon (7-4, 4.11 ERA). Taillon...

Cedric Mullins is expected to represent the Orioles at the All-Star Game, finding out Sunday night whether he made it as a starter. Trey Mancini already confirmed his participation in the Home Run Derby. They can hang out in Denver. Ryan Mountcastle won't be tagging along, but he's distracted with strengthening his candidacy for American League Rookie of the Month. With more prestigious hardware in his sights. Astros starter Luis Garcia hung a slider tonight with two outs in the top of the...

What about this and what about that? Why is this taking so long, and will that ever happen? And where's Chris Davis? Oh, the questions never stop, which is why mailbags exists. They're also a popular filler for sportswriters - our version of breadcrumbs. Some might call it lazy. Those accusers are driven to another county and pushed out the door. And I'll go the extra mile to find a new movie sequel title. You ask 'em and I answer 'em, and then someone else asks the exact same thing and I...

Birdland has likely noticed and no doubt enjoyed some great starts by both individual players and teams on the Orioles farm. Through Sunday's games, three of the O's four full-season affiliates are playing .667 ball or better. The four teams have a combined record of 29-18 (.617) and the Orioles rank seventh among major league organizations in minor league win percentage. Among several players off to great starts are two of the club's best young prospects. Pitcher Grayson Rodriguez is 1-0...

Shortstop Freddy Galvis remains out of the Orioles lineup tonight, his day-to-day status extending at least to Saturday. Ramón Urías is the shortstop for the series opener in Oakland. Pat Valaika is the second baseman. Rio Ruiz is playing third base instead of Maikel Franco. Austin Hays stays in left field and DJ Stewart stays in right. Ryan Mountcastle gets another start at first base, with Trey Mancini the designated hitter. Left-hander John Means has allowed one run or fewer in eight...

Here's a summer activity that might interest some fans. Track the performances of Orioles catcher Adley Rutschman and Royals shortstop Bobby Witt Jr. Then stay on it through the rest of their professional careers. Rutschman is going to play for Double-A Bowie after games begin in early May. The Royals are suggesting that Witt could break camp with the team at 20 and with no experience beyond rookie ball. General manager Dayton Moore is on record as saying the team will be "very open-minded"...

As Orioles executive vice president/general manager Mike Elias rattled off the names of shortstop prospects in the system during a recent Zoom conference call, the topic born from a question relating to how the club might fill the position next summer, he made sure to include the 37th overall selection in the 2018 draft. The former teammate of catcher Adley Rutschman at Oregon State University. A product of the final draft under the previous front office and head of scouting. Cadyn Grenier has...

As the Orioles approached their recent instructional league camp, they knew a few things that would be important to consider. One is that building defensive versatility is never a bad thing for a player. If he can play multiple positions, his value to the team and the sport go up. The Orioles also knew they had drafted and acquired seven shortstops via the draft or trade since Mike Elias took over as executive vice president and general manager. So the want-to - to expand defensive resumes for...

While the Orioles wait to make official their decision to pick up the option on José Iglesias' contract, the only potential glitch tied to finances, they're in the developmental stages with a handful of shortstop prospects who could vie for the position. Don't bother checking out the fall instructional camp in Sarasota, Fla. because it's closed to the public, but the group of 55 includes Baseball America No. 8 organizational prospect Gunnar Henderson, No. 10 Jordan Westburg, No. 15 Adam...

While the Orioles were learning about pitcher Asher Wojciechowski over the summer, the right-hander was busy learning more about himself. Wojciechowski admitted that he began to feel fatigued later in the season as it extended beyond the usual point when he's done. He had to push through it, with manager Brandon Hyde providing some extra rest along the way. After completing his final start in Boston, where he tossed six scoreless innings, Wojciechowski said he'd devote the offseason to...
