The New York Mets have called up right-handed pitcher Brandon Sproat, their No. 5 organizational prospect on MLBPipeline.com, who will make his Major League debut Sunday, September 7, against the Cincinnati Reds at Great American Ball Park. First pitch is scheduled for 1:40 p.m. EDT.

Sproat, 24, was born in Pensacola, Fla., and played at the University of Florida before being selected by the Mets in the second round of the 2023 MLB Draft. He signed with New York on July 14, 2023, after completing his senior season. He was first assigned to the Florida Complex League that August and did not debut professionally until 2024.

Role with Mets & Kodai Senga Situation

Under second-year manager Carlos Mendoza, Sproat enters a Mets rotation that includes Sean Manaea, Nolan McLean, Kodai Senga, Jonah Tong, Clay Holmes, and David Peterson. Tylor Megill is currently on the 60-day injured list.

Sproat’s call-up also makes him the third rookie starter the Mets have used this season, joining fellow top prospects McLean and Tong who have already given the rotation a lift.

Kodai Senga News

If Kodai Senga does get sent down, it would mark a stunning twist for a pitcher expected to anchor the Mets’ rotation. MLB insider Ken Rosenthal addressed the situation on Foul Territory, noting that Senga must consent to any demotion under his contract.

“My guess would be yes, if they have a detailed plan for him on what is wrong and what he needs to fix and if it can really help them,” Rosenthal said. He cautioned that if the move is simply about creating a roster spot — with Brandon Sproat debuting Sunday as the third rookie starter to enter the mix — then Senga has every right to ask, “What are we doing here? What is the plan? When am I coming back?”

Rosenthal added that Senga’s struggles appear tied to command and perhaps lingering injuries, leaving it unclear whether the Mets view his issues as mechanical, execution-based, or something else entirely.

Minor League Career

This season with Triple-A Syracuse, Sproat made 26 appearances and 25 starts, posting an 8-6 record with a 4.24 ERA. Across 121 innings, he allowed 97 hits, 57 earned runs, nine home runs, 53 walks, and struck out 113, finishing with a 1.24 WHIP.

That season, Sproat was selected to the Futures Game in Arlington, Texas, earned Eastern League Pitcher of the Year honors with Binghamton, was named a postseason All-Star, and later picked up International League Pitcher of the Month with Syracuse.

In two professional seasons, he has pitched in 50 games and 48 starts, compiling a 15-10 record and a 3.83 ERA with 244 strikeouts in 237.1 innings.

Scouting report

According to Baseball Savant, Sproat’s fastball can touch triple digits and typically sits 95–98 mph, though hitters at Triple-A hit .380 off it this season. He complements it with a sinker at similar velocity that generates ground balls, an upper-80s changeup effective against lefties, an 84–86 mph sweeper, an 88–90 mph slider, and a 79–81 mph curveball.

His scouting grades are fastball 55, curveball 45, slider 55, changeup 60, control 50, overall 50.

Standings outlook
The Mets (75-65) begin a three-game series in Cincinnati on Friday night. They trail the first-place Philadelphia Phillies by six games in the National League East but currently hold the third NL Wild Card spot, four games ahead of the San Francisco Giants. The Reds (70-70) are five games behind the Mets in the Wild Card race.
