Krol, 27, made just one major-league appearance after having his contract purchased from Triple-A Salt Lake on May 19. Over two innings of relief on Sunday, Krol allowed no runs on one hit, one walk, and two strikeouts.
It wouldn’t be a huge surprise if Krol was traded or claimed off waivers, as he also enjoyed significant success at Salt Lake prior to being promoted, posting a 1.71 ERA and 1.19 WHIP over 21 innings. He’s had big-league success in the not-too-distant past, throwing for a 3.18 ERA and 1.31 WHIP over 63 appearances (51 innings) for the Braves in 2016, so there’d seem to be a decent chance that another organization would want to take a chance on him.
Right-hander Akeel Morris was recalled to take Krol’s roster spot. This will be the 25-year-old’s third big-league stint of the season.
