Red Sox facing tough decision on promising pitching prospect

The Red Sox are approaching a crossroads with regards to right-hander Bryan Mata. As noted by Chris Cotillo of MassLive, Mata has begun a rehab assignment as he works his way back from a hamstring strain that he suffered in February. The 25-year-old was once one of the club’s top pitching prospects but has struggled with injuries and ineffectiveness over the past two seasons, pitching to a combined 6.39 ERA in 31 innings of work across all levels of he minors since the start of the 2023 campaign.

While the rehab assignment for a struggling pitcher who has yet to make his big league debut wouldn’t typically be especially notable, Mata’s is because the righty is out of options. Given that, the Red Sox will have to make a decision regarding his future in the organization once his rehab clock runs out on June 12. If the club isn’t willing to offer Mata a spot on the active roster, they’ll need to designate him for assignment and risk losing him on waivers to get the chance to outright the young righty to the minor leagues. MassLive’s Sean McAdam reported in February that the Red Sox expect Mata to be claimed if he’s exposed to waivers, though it’s possible that could change depending on how he looks throughout his rehab assignment.

Losing Mata on waivers would be a frustrating outcome for the Red Sox given the tantalizing talent he flashed prior to injuries sidetracking his career. In his most recent healthy season, the right-hander pitched to a strong 2.49 ERA in 83 innings while advancing through four levels of the minor leagues, including a 1.85 ERA in 10 appearances at the Double-A level and a 3.47 ERA in five starts at Triple-A. That season, Mata struck out a whopping 30.3% of batters faced, albeit with an elevated 13.3% walk rate. If the righty can get anything close to those huge strikeout numbers during his rehab assignment, it could certainly make sense for the club to offer him a role in the bullpen given the number of optionable relief arms they’re currently utilizing.

• Orioles fans received some tough news from down on the farm on Friday, when the club announced that top third base prospect Coby Mayo suffered a fractured rib and has been placed on the minor league injured list. The Orioles indicated that Mayo will be out for “several weeks” due to the injury. It’s a frustrating setback for the 22-year-old, who is a consensus top-30 prospect in the sport and has impressed with a .291/.359/.605 slash line in 42 games at the Triple-A level this year. It was certainly plausible that the club could turn to Mayo as a starting option at some point in the near future given his fantastic play and the struggles of fellow top prospect Jackson Holliday, though this injury surely represents a setback for Mayo’s timeline to be called up to the majors. Jorge Mateo is currently rounding out the club’s starting infield mix in the majors alongside youngsters Jordan Westburg and Gunnar Henderson.
• Blue Jays ace Kevin Gausman has been off to a rough start this season, with a 4.89 ERA through nine starts despite a decent 3.50 FIP. Gausman’s struggles this season are particularly surprising given his utter dominance in recent years; from 2021 to ’23, the right-hander pitched to a 3.10 ERA (132 ERA+) with an even better 2.79 FIP. Gausman spoke to reporters (including MLB.com’s Keegan Matheson) yesterday about his frustrating results this season and described the campaign as an “uphill battle” to this point before suggesting that he “probably should have gone on the IL” at the start of the season. The righty battled shoulder soreness throughout spring training but nonetheless opened the season in the club’s rotation amid injuries sidelining much of the club’s starting pitching depth, including Alek Manoah and Yariel Rodriguez.
