Kyle Isbel Diagnosed With Grade 3 Plantar Fascia Tear
The Royals placed center fielder Kyle Isbel on the 10-day injured list last night due to plantar fasciitis. Manager Matt Quatraro announced at the time that Isbel was undergoing an MRI to determine the severity of the issue. That imaging came back with unfavorable results, it seems. The Royals announced this morning that Isbel has a Grade 3 tear of a portion of the plantar fascia in his left foot. Anne Rogers of MLB.com reports that the team isn’t putting a formal timetable on his return but that it’ll be quite some time before he’s even able to resume baseball activity — let alone embark on a rehab assignment or return to the big league roster.
There’s better news on righty Seth Lugo, who exited last night’s game after taking a 106 mph comebacker to the head. Lugo rather incredibly quickly rose back to his feet, assuring distraught former Mets teammate Brandon Nimmo (who hit the ball in question) that he thought he was OK. Per the Royals, a CT scan was clean. Lugo will continue to be monitored, but for the time being, it seems he’s thankfully avoided any kind of significant injury.
Isbel, 29, has handled the vast majority of the Royals’ center field work this season. He’s long graded as a plus defender on the grass, though his grades in 2026 have dipped a bit. That’s not entirely surprising, given the full context of his season; Jaylon Thompson of the Kansas City Star writes that Isbel has been playing through considerable pain in his left foot for quite some time. He finally reached a point where he couldn’t continue. Even with that ailing foot, Isbel drew a positive grade from Statcast’s Outs Above Average (4) and was only slightly below average in the estimation of Defensive Runs Saved (-2).
At the plate, Isbel has hit at his typical levels. He entered the season with a well below-average .235/.288/.365 batting line in his career (78 wRC+) and has turned in a .244/.298/.354 slash (80 wRC+) that closely mirrors his career marks.
With Isbel sidelined indefinitely, the Royals will piece together the center field mix via in-house options for the time being. Missouri native and Mizzou product Kameron Misner was recalled from Triple-A and is getting the start today. Lane Thomas has also logged some time in center this season and got the start in Isbel’s place last night. Utilityman Tyler Tolbert has four innings in center this season but logged 100 frames there last year. He probably won’t draw many starts in center but could slot in if he’s used as a pinch-runner (as was the case last night) or if the Royals make other defensive/lineup shuffles midgame during Isbel’s absence.
The veteran Thomas signed a one-year deal with Kansas City over the winter. He’s not hitting for any power whatsoever in 2026 but is sporting a career-best 15.8% walk rate in 152 plate appearances. He’s slashing .234/.362/.315 overall and, as is so often the case, has been a menace to left-handed opponents (.262/.395/.361). There’s a natural platoon to be formed between the righty-swinging Thomas and lefty-swinging Misner. Though Misner has batted just .203/.260/.325 in 231 MLB plate appearances with the Rays (and one with Kansas City last night), the former first-rounder has bludgeoned Triple-A pitching at a .276/.373/.547 pace in 252 plate appearances this year. He belted 13 homers and swiped 11 bags with the Storm Chasers prior to yesterday’s recall to the majors.
Royals Designate Elias Díaz For Assignment
The Royals announced that they have recalled outfielder Tyler Tolbert. To open a roster spot for him, catcher Elias Díaz has been designated for assignment. Kansas City’s 40-man count drops to 39.
Díaz, 35, signed a minor league deal with the Royals in the offseason. He had his contract selected to the big league roster just over a month ago. That gave the Royals a three-catcher setup, with Díaz backing up Carter Jensen and Salvador Perez. In that limited role, Díaz has done fairly well, hitting two home runs in 23 plate appearances.
Getting bumped off the roster is probably more about other players on the roster than it is about anything Díaz has done. At the time Díaz was called up, Perez was dealing with some hip soreness and was in need of some extra rest. That has seemingly helped, as Perez hit .200/.236/.350 over March and April but has a .231/.297/.400 line in May so far.
In the outfield, Lane Thomas is dealing with a sore hamstring, per Jaylon T. Thompson of The Kansas City Star. Thomas hasn’t hit the injured list but also hasn’t started a game since Tuesday. By bringing up Tolbert and cutting Díaz, the Royals have sacrificed their three-catcher arrangement in order to add some extra outfield depth.
Díaz now heads into DFA limbo, which can last as long as a week. The waiver process takes 48 hours, so the Royals could take five days to explore trade interest. As a 35-year-old backstop, he won’t have a ton of value, but they might get some calls. Atlanta just lost both Sean Murphy and Drake Baldwin to the injured list recently, so they could really use some extra catching depth. Cal Raleigh, Francisco Alvarez and Ryan Jeffers also hit the IL this month, leaving the Mariners, Mets and Twins without their starting catchers.
Thanks to his two homers, Díaz has a .227/.261/.591 line and 128 wRC+ this year, though in a tiny sample of 23 plate appearances. He has a .246/.300/.385 line and 78 wRC+ in his career. Defensively, he has received good grades for his throwing and blocking. He has mostly been graded as a poor framer but has been around average in recent years.

Royals Recall Mason Black
Right-hander Mason Black is set for his Royals debut on Sunday. He’ll be joined by catcher Elias Diaz, who had his contract selected by the club. Right-hander Mitch Spence and infielder Tyler Tolbert were optioned to make room for Black and Diaz, the team announced. Right-hander James McArthur was moved to the 60-day IL to clear a 40-man spot for Diaz.
Kansas City acquired Black from the Giants for right-hander Logan Martin 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.
The 26-year-old Black was almost exclusively used as a starter in San Francisco, but he’s 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.
Spence joined the organization in February following a trade from the Athletics. He didn’t break camp with the team, but came up in early April when right-hander Luinder Avila was sent down. Spence was tagged for six earned runs across four innings in mop-up duty against the Yankees on Saturday. He’ll head back to Triple-A after just the one big-league appearance.
Tolbert made the team out of camp, beating out Drew Waters for a roster spot. Michael Massey‘s calf strain in MLB Spring Training helped Tolbert and Nick Loftin earn roster spots. Loftin was sent down when Massey returned. Now, it’s Tolbert’s 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.
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’s late-inning group when he last pitched, recording 18 saves in 2024.

Royals Select Luke Maile
The Royals announced that they have selected the contract of catcher Luke Maile. Infielder Tyler Tolbert was optioned to Triple-A Omaha to open an active roster spot. To get Maile onto the 40-man, right-hander Alec Marsh was transferred to the 60-day injured list.
The Royals already have Salvador Perez and Freddy Fermin on the roster, so this move gives them three catchers. However, Perez was removed from last night’s game due to left hip soreness, per Anne Rogers of MLB.com. Perez hasn’t been placed on the injured list but he’s not in the lineup today.
Perhaps he’ll be unavailable for a few days, which would explain why Maile is now up with the club. The 34-year-old veteran signed a minor league deal with the Royals in the offseason. He opted out when he didn’t make the Opening Day roster but returned on a fresh deal shortly thereafter.
He is out to a strong start in Triple-A, hitting .286/.434/.381, though a .379 batting average on balls in play is helping him out somewhat in a small sample. For his big league career, he’s generally been a glove-first guy. He has a .208/.274/.319 batting line in 1,250 plate appearances but comes with a strong reputation for his throwing, blocking and work with a pitching staff. He should back up Fermin while Perez gets a breather.
As for Marsh, it’s not surprising to see him hit the 60-day IL. He has been battling shoulder soreness since the offseason and has spent the entire season on the 15-day IL so far. As of about a week ago, he was slated to restart his throwing program after a setback. The 60-day clock is retroactive to the start of the season, so he is eligible for reinstatement later this month. But given his current status, he’ll need far longer than that to get in game shape.

Royals Select Tyler Tolbert
The Royals announced Monday that they’ve selected the contract of infielder/outfielder Tyler Tolbert from Triple-A Omaha. They had an open 40-man spot already and only needed to clear an active roster spot, which they did by placing outfielder Dairon Blanco on the 10-day IL due to right Achilles tendinopathy.
Tolbert, 27, will make his MLB debut the first time he gets into a game. The former 13th-round pick has never hit much in the minors but nevertheless leads all of Minor League Baseball with 215 steals dating back to the 2021 season. That’s partially due to the fact that some others who might’ve challenged him for that lead instead made their way to the big leagues sooner and have stuck there, but it’s nonetheless an impressive mark, particularly considering that he’s only been caught 15 times — a staggering success rate of 93.5%
Despite is impressive wheels, however, Tolbert’s bat is quite suspect. He turned 27 in January but has just 99 plate appearances above the Double-A level. He’s hit .153/.258/.177 in that small sample and carries a .269/.337/.391 output in 1036 Double-A plate appearances. Overall, Tolbert is a .245/.333/.359 hitter in pro ball.
On the defensive side of the coin, Tolbert has spent the majority of his career up the middle. Shortstop has been his primary spot on the diamond, but he has nearly 1800 innings in the outfield (1338 in center) and 528 frames as a second baseman under his belt. He’ll be a bench player for manager Matt Quatraro, offering a high-end pinch runner late in games or a defensive replacement in the outfield. He doesn’t draw particularly strong grades for his up-the-middle glovework, but he’d be an upgrade over defensively challenged left fielder MJ Melendez.
Tolbert will seemingly take the role of a speedy bench player, which has been Blanco’s primary job in recent years. Since the start of 2022, Blanco has appeared in 165 games for Kansas City but has only been sent to the plate 278 times. He has a roughly league average line of .258/.314/.417 but has stolen 58 bases in 70 attempts. His sprint speed was ranked in the 97th percentile last year and in the 100th in 2023.
It was noted back in February that Blanco was dealing with soreness in his Achilles. He eventually made the Opening Day roster but it seems the issue has lingered enough that the club will put him on the shelf for a while.
