Hall, 24, was a sixth-round pick in the 2015 draft, meaning he’d have been eligible for the Rule 5 draft this winter had he not gone onto the MLB roster. Instead, he’ll get a taste of the big leagues before perhaps competing for a job in camp.
Certainly, Hall has had an excellent season thus far in the upper minors. He opened the year in a relief capacity despite generally succeeding in the rotation in the lower minors. But Hall has thrown well enough overall that he worked as a starter upon rising to Triple-A. All told, he has recorded 114 1/3 innings of 2.13 ERA ball on the year, with 10.6 K/9 against 3.5 BB/9.
Barbato was also a sixth-round pick and has typically been quite effective in the upper minors. He spent most of the year turning in good numbers at Triple-A, with a 1.45 ERA in 37 1/3 innings. Unfortunately, that has not yet translated to the major-league level thus far.
Though Barbato’s MLB opportunities have been limited over the past three seasons, that’s due largely to the outcomes. In his seven MLB relief appearances this year with Detriot, he coughed up nine earned runs on 11 hits (including three home runs) while allowing five walks and managing only a pair of strikeouts.
