Heaney has breezed through the Minor Leagues since the Marlins picked him ninth overall in the 2012 First-Year Player Draft out of Oklahoma State. He threw 33 consecutive scoreless innings last season between Class A Advanced Jupiter and Jacksonville and is once again at peak form to start this year. In 17 innings over three starts this season, the left-hander has a 1.56 ERA and a 16-to-3 strikeout-to-walk ratio.
Relievers Grant Dayton and James Nygren combined for three shutout innings to close out the one-hitter Tuesday. Catcher J.T. Realmuto, the Marlins No. 9 prospect, led the Suns offense. He went 3-for-5 with a double and a run. Heaney even helped his own cause at the plate, driving in a run with a sacrifice bunt.
