Prospect watch

Zephyr Field was abuzz following the call-up of left-handed pitcher Andrew Heaney from Double-A Jacksonville. The 23-year-old, ranked by MLB.com as the top left-handed pitching prospect in baseball, is expected to make his Triple-A debut Thursday against Oklahoma City. It’s a fitting start for the soon-to-be 23-year-old, who was a 2012 first-round pick out of Oklahoma State.

Heaney comes to the Zephyrs with a record of 4-2 in nine games and an ERA of 2.35. He struck out 52 batters in 53.2 innings. He pitched 7.2 innings Saturday night against Pensacola, striking out eight and walking one.

To make room for Heaney, pitcher Jay Rogers was sent to Jacksonville and Matt Montgomery was sent to Single-A Jupiter. The Marlins also sent pitcher Henry Rodriguez back to the Zephyrs from Miami.

Dinged up

Although he has put up solid numbers, Flynn has not found success against the RedHawks. He fell to 0-4 against Oklahoma City following Tuesday’s loss. On April 8, he gave up eight runs and 10 hits in an 8-1 loss to the RedHawks.
