Soroka was limited in 2018 (56.1 IP combined AAA/MLB), but he threw 143 and 153.2 innings in 2016 and 2017, respectively. All told, Soroka wound up throwing 191 innings in 2019, combined between AAA/MLB and the postseason. By comparison, Graterol only has 224.2 innings for his entire pro career to date, barely more than Soroka's 2019 output. Graterol's single season high is 102, significantly less than TWO pre-2019 Soroka seasons. Also, while both guys had shoulder issues, Graterol has also had Tommy John surgery already, suggesting even further caution.
