Mets to bring up top pitching prospect for debut vs. Rays

The Mets are bringing up top pitching prospect Christian Scott for his debut against the Rays on Saturday. At least temporarily, he steps into a rotation that includes Jose Quintana, Luis Severino, José Buttó and Sean Manaea.

If Scott sticks in the rotation, right-hander Adrian Houser could be the odd man out. Manager Carlos Mendoza told reporters that Houser will be available out of the bullpen for next week’s series against the Cardinals, which runs from Monday through Wednesday (video link via SNY). It’s not clear whether that’ll be a permanent move. The Mets are off next Thursday before playing on 13 straight days between May 10-22.

Mendoza suggested the Mets haven’t determined how they’ll proceed for that nearly two-week stretch. They could operate with a six-man rotation to give their starters an extra day of rest. If they want to go back to a five-man rotation, the decision would likely come down to optioning Scott back to Triple-A Syracuse or keeping Houser in relief. Joel Sherman of the New York Post wrote Thursday the Mets are committed to giving Scott at least two starts — Saturday's outing in Tampa Bay and a home start next weekend against the Braves — before determining whether he should stick in the rotation.

Scott has had an excellent five-start run to begin his time in Triple-A. Over 25 1/3 innings, he owns a 3.20 ERA behind a massive 38.3% strikeout rate. Houser, on the other hand, has had a tough first month in Queens. Acquired alongside Tyrone Taylor in an offseason deal with Milwaukee, Houser held a rotation spot through April. He has allowed 8.14 earned runs per nine across six starts as he’s struggled to find the strike zone.

The 31-year-old righty has walked nearly 15% of opposing hitters. He has issued multiple free passes in all six appearances, including four walks over five innings in yesterday’s outing against the Cubs. Houser’s strikeout rate has dropped to a career-low 11.7%, while his 44.4% ground-ball percentage is his lowest since 2018.

Houser was a decent back-end starter for Milwaukee a year ago. In 111 1/3 innings, he turned in a 4.12 ERA with a personal-best 7.1% walk percentage. He has never gotten huge strikeout tallies, but last season’s 20% mark was far better than he has managed thus far. While Houser’s velocity hasn’t significantly changed, he clearly has yet to find his command.

That could push him into low-leverage relief if Scott hits the ground running and the Mets want to stick with a five-man starting staff. New York doesn’t have the luxury of sending Houser to the minor leagues. He has over five years of service time, so he’d have to agree to an optional assignment and would have the right to test free agency if he were outrighted off the 40-man roster.
