2) Mike Vasil
Mike Vasil had a decent year in 2022 in his first full season in professional baseball, making it up to High-A and posting a 3.53 ERA in 18 appearances. He was considered one of the better pitching prospects in the Mets system entering the season, but that's mainly because the farm system was very subpar.
This season, Vasil has put his name on the map as a guy who can realistically be a part of the Mets 2024 rotation at some point thanks to his performance this past season. The right-hander had a 3.71 ERA in 10 starts for AA Binghamton before earning a mid-season promotion to AAA.
His 5.30 ERA isn't pretty, but Syracuse is a tough environment to pitch in, and he had some nice stretches as the season progressed. His best moment of the season featured a game against the Yankees AAA affiliate. He took a no-hitter into the ninth inning in one of the more dominant appearances we've seen from a Mets pitching prospect in a long time.
He pitched well down the stretch for Syracuse to the point where Mets fans wanted to get a look at him before the season ended. That didn't happen, but Vasil moved all the way up to ninth on the Mets prospect rankings and is listed as the team's best pitching prospect. He was ranked 21st on Opening Day last season in a bad system, and is now ninth in a good system. He's risen to the point where he is a legitimate prospect fans should be excited about.
