Jac Caglianone, 1B, Royals: When he was at Florida, Caglianone was known for having some of the best power in Division I. He’s showing the same traits in pro ball. His homer off Trey McGough on Sunday was one of the hardest-hit home runs we will see this spring. Caglianone’s 115.4 mph shot was estimated at 435 feet. The Royals only hit one ball 115+ mph in the entire 2024 regular season.

Chandler Simpson, OF, Rays: Simpson wasted no time showing why he’s one of the most dynamic players in the minors. His 80-grade speed and table-setting skills were on display, but J.J. Cooper writes this morning that Simpson’s defense is what caught his attention the most.

Dillon Dingler, C, Tigers: Last August, the Tigers made Dingler their backup catcher. On Sunday he offered a glimpse of what he can offer in the role. Dingler may be known for his defense, but he also has real power. He homered off of Fernando Cruz. The 111.6 mph exit velocity was the third-hardest hit ball of the day, trailing only fellow prospects Jac Caglianone and Coby Mayo.

C.J. Kayfus, 1B, Guardians: Kayfus, the Guardians’ No. 8 prospect, homered and walked twice in three plate appearances in Cleveland’s 14-2 win over the Angels. Kayfus yanked a Connor Brogdon changeup 403 feet to right field. It had a 108.2 mph exit velocity that would have cleared any fence in the big leagues. Kayfus is one of a number of highly regarded Guardians’ first base prospects.

Eiberson Castellano, RHP, Twins: Castellano, a MLB Rule 5 pick of the Twins, struck out three in one inning of work in his first spring training outing. Castellano sat 95-97 mph with his fastball and threw plenty of strikes with both his fastball and his low-80s curveball. Castellano froze Bryan Reynolds with a curve for his first strikeout, and then did the same thing to Ke’Bryan Hayes. After falling behind 3-0, he worked back to a full count before walking Jack Suwinski. He then finished out his excellent inning by getting Jared Triolo swinging on a curveball that dove into the dirt.

Cooper Ingle, C, Guardians: Guardians’ catching prospect Cooper Ingle went 2-for-2 with a walk and 2 RBIs as the Guardians bludgeoned the Angels on Sunday. It was an impressive 2025 spring debut for the catcher. He also walked in his only 2024 spring training appearance, so he’s sporting a 1.000 batting average, a 1.000 OBP and a 2.000 OPS in his four spring training plate appearances.

JJ Wetherholt, SS, Cardinals: Making the start in his first spring training game as a Cardinal, shortstop JJ Wetherholt went 2-for-3 with a home run. The Cardinals’ 2024 first-round pick and No. 1 prospect hit an opposite-field fly ball three-run homer off A.J. Blubaugh in the fifth inning. He had earlier singled off Bryan King in the fourth inning and scored on a Victor Scott II single.

Injury News

Alejandro Rosario, RHP, Rangers: Rangers RHP Alejandro Rosario will miss all of 2025 with an elbow injury that will require surgery, president of baseball operations Chris Young told reporters Sunday morning. Young said Rosario suffered an “acute” injury during a bullpen session. It’s unclear what type of surgery Rosario will need. 

“It’s likely UCL. I don’t want to officially say, but yeah, it’s elbow and will probably require Tommy John,” Young said.

If Rosario undergoes a full Tommy John surgery–and not an internal brace procedure–he’s unlikely to return before midway through the 2026 season. One of the breakout pitching prospects of 2024, Rosario ranked No. 49 on Baseball America’s Top 100 and No. 3 in the Rangers system entering 2025.

Blake Mitchell, C, Royals: The Royals’ enviable minor league catching depth took a hit over the weekend, as manager Matt Quatraro told reporters Blake Mitchell is expected to miss the next 4-6 weeks with a broken right hamate bone. Mitchell, 20, was the eighth overall pick in the 2023 draft and entered the season ranked No. 75 in Baseball America’s Top 100 Prospects. He spent the majority of 2024 with Low-A Columbia where he hit .238/.376/.439 with 18 homers and 25 steals, and was expected to open the year at High-A Quad Cities.
