Orioles call up Contreras and Rivera, option Hiraldo and DFA Machín

The Orioles are tampering with their roster again, with two more players coming in and two more going out.

Roansy Contreras was activated from the taxi squad and had his contract selected from Triple-A Norfolk, and he’ll work in bulk relief tonight, his first major league appearance since Sept. 29, 2024 with the Angels. He posted a 3.73 ERA in 28 appearances (14 starts) with Norfolk.

Infielder Emmanuel Rivera also had his contract selected.

To create room, the Orioles optioned Yaramil Hiraldo, who was charged with three runs last night in 1 1/3 innings and has a 5.65 ERA in 12 games, and they designated infielder Vimael Machín for assignment. They also transferred pitcher Brandon Young (hamstring) to the 60-day injured list, which ends his season.

Contreras will be the 64th player used by the Orioles this season, two more than the franchise record set in 2021.

The Marlins hold the major league record of 70 in 2024.

Right-hander Shawn Dubin still hasn’t joined the club after yesterday’s waiver claim. He made 23 appearances with the Astros and registered a 5.61 ERA and 1.481 WHIP in 25 2/3 innings. Three of his last four outings came against the Orioles, when he allowed nine runs in four innings.

Left-hander Dietrich Enns will be the opener tonight, his fourth career start in 27 games. He’s made eight relief appearances with the Orioles and posted a 3.97 ERA and 1.500 WHIP with 17 strikeouts in 11 1/3 innings. He allowed one run in one inning against the Red Sox in Boston.

Enns started twice for the Tigers this season, tossing five scoreless innings with one hit allowed against the Athletics and allowed seven earned runs (eight total) and eight hits in four innings in D.C.

Red Sox right-hander Brayan Bello is 10-6 with a 3.07 ERA in 23 games (22 starts). He shut out the Yankees on three hits in seven innings in his most recent start at Yankee Stadium.

Bello faced the Orioles on May 23 in Boston and allowed two runs and six hits in four innings, and he struck out seven batters. He owns a 3.75 ERA in seven career starts against them.

Gunnar Henderson is 5-for-16 with three doubles and a home run against Bello.

The Red Sox’s bullpen has a 3.41 ERA, third best in the majors. It ranked 25th last season at 4.36.

The Orioles announced the hiring of Rosina Lanson as chief strategy officer. She will be responsible for overseeing corporate strategic planning, data and analytics, and technology to “drive multifaceted problem-solving and research in support of the business operations of both the Orioles and MASN.”

Lanson will serve as a strategic partner to business unit leaders across various departments to drive operational efficiencies, optimize revenue, and achieve strategic plan objectives.

“I’m honored to join such an iconic organization and be part of something so meaningful to Baltimore,” she said in a statement. “I look forward to contributing my experience from across the industry, working alongside the talented team here as we continue to grow and innovate.”

Lanson, a St. Louis native, joins the Orioles from Major League Baseball, where she launched and led the club business operations and strategy advisory function, overseeing efforts to leverage data and strategic insights to drive revenue and fan engagement across all 30 clubs. She also spent five seasons with the New York Jets, building and leading business strategy.
