Right-hander Mason Black<\/a><\/strong> is set for his Royals debut on Sunday. He\u2019ll be joined by catcher Elias Diaz<\/a><\/strong>, who had his contract selected<\/a> by the club. Right-hander Mitch Spence<\/a><\/strong> and infielder Tyler Tolbert<\/a><\/strong> were optioned to make room for Black and Diaz, the team announced. Right-hander James McArthur<\/strong><\/a> was moved to the 60-day IL to clear a 40-man spot for Diaz.<\/p>\n Kansas City acquired Black from the Giants for right-hander Logan Martin<\/a><\/strong> in November. Black had some fanfare when he first came up with San Francisco in 2024, but he failed to provide consistent results. The righty finished his Giants tenure with a 6.47 ERA in 10 games over the past two seasons.<\/p>\n The 26-year-old Black was almost exclusively used as a starter in San Francisco, but he\u2019s moved to a relief role with Kansas City. He has a 3.86 ERA over seven appearances at Triple-A this year. Black locked down the first two saves of his professional career with Omaha. Despite the full-time move to the bullpen, Black has just a 12.5% strikeout rate so far. Often, those numbers improve when starters make the change to relief work, as their stuff usually plays up in shorter outings.<\/p>\n Spence joined the organization in February following a trade from the Athletics. He didn\u2019t break camp with the team, but came up in early April when right-hander Luinder Avila<\/a><\/strong> was sent down. Spence was tagged for six earned runs across four innings in mop-up duty against the Yankees on Saturday. He\u2019ll head back to Triple-A after just the one\u00a0big-league appearance.<\/p>\n Tolbert made the team out of camp, beating out Drew Waters<\/a><\/strong> for a roster spot. Michael Massey<\/a><\/strong>\u2018s calf strain in MLB Spring Training helped Tolbert and Nick Loftin<\/strong><\/a> earn roster spots. Loftin was sent down when Massey returned. Now, it\u2019s Tolbert\u2019s turn. He appeared in eight games with the Royals, with the majority of his work coming as a pinch runner or defensive replacement. Tolbert managed a hit in five plate appearances.<\/p>\n McArthur missed the entire 2025 season after undergoing elbow surgery. He opened the 2026 campaign on the 15-day IL due to elbow inflammation. His return timeline is uncertain. The righty was a key member of Kansas City\u2019s late-inning group when he last pitched, recording 18 saves in 2024.<\/p>\n Photo courtesy of Scott Sewell, Imagn Images<\/em><\/p>\n<\/p><\/div>\n \u2018 The preceding article may include information circulated by third parties \u2019 <\/em><\/p>\n \u2018 Some details of this article were extracted from the following source www.mlbtraderumors.com \u2019 <\/em><\/p>\n","protected":false},"excerpt":{"rendered":" Right-hander Mason Black is set for his Royals debut on Sunday.
