Corey Oswalt
Speaking of spot starters, Corey Oswalt made his major league debut for the Mets back in 2018 as a spot starter and ended up starting 12 out of the 17 games he appeared in for New York that year.
Oswalt did appear in two games out of the bullpen for the Mets in 2019, but the rotation remained healthy for the most part, so he was relegated to the minor leagues. Oswalt spent the majority of the season in Triple-A Syracuse, where he recorded a very respectable 2.82 ERA in 18 starts.
Corey has been given a more prominent role in the Mets Summer Camp and is certainly a name to watch in case a spot opens up in the rotation.
The Mets gave him a big spotlight as he was entrusted to start the second intrasquad game against the Yankees last Sunday, meaning they wanted to give him an opportunity to earn a spot on the team just prior to the start of the season.
While he admittedly got roughed up, giving up 2 runs over 3 innings, Oswalt has overall had a very impressive Spring Training this season, posting an overall 2.45 ERA. After his impressive season with Syracuse last year, he could serve as a viable candidate to potentially replace an injured starter.
