Marlins option struggling Andrew Heaney back to Triple-A - MLB

Marlins pitching prospect Andrew Heaney allowed five more runs over 3 2/3 innings in Saturday afternoon’s start against the Cardinals, bumping his ERA up to 6.53 over four starts spanning 20 2/3 innings. As a result, the Marlins have optioned him back to Triple-A New Orleans, the team announced.

Heaney, 23, was rated the #29 overall prospect by MLB.com and #30 by Baseball America and Baseball Prospectus entering the season. He had a good major league debut, holding the Mets to one run over six innings, but followed that up by allowing five runs to the Phillies and four to the Athletics prior to Saturday’s start.

The Marlins made some additional roster moves as well, reinstating starter Tom Koehler from the paternity leave list and activating shortstop Adeiny Hechavarria from the disabled list. Outfielder Jake Marisnick was optioned back to Triple-A New Orleans.

LOS ANGELES — Giancarlo Stanton, Josh Donaldson, and Tommy Kahnle were activated by the New York Yankees ahead of their weekend series against the Los Angeles Dodgers.

New York cleared three roster spots after a 1-0 loss at Seattle, optioning infielder-outfielders Oswaldo Cabrera and Franchy Cordero to Triple-A Scranton/Wilkes-Barre along with left-hander Matt Krook.

Stanton, Donaldson and Kahnle all played in a rehab game for Double-A Somerset. Stanton was hitless in three at-bats in his first appearance since injuring his left hamstring on April 15.

Donaldson went 1 for 4 in his fourth rehab game as he comes back from a strained right hamstring originally sustained on April 5.

Kahnle pitched one inning, giving up one run and one hit and walking two. He has been out since spring training with right biceps tendinitis.

Aaron Boone said he wasn’t concerned about Stanton returning after playing in just one rehab game. He did say that Stanton likely will be a designated hitter for a couple of weeks after rejoining the Yankees.

New York is missing centerfielder Harrison Bader, who strained his right hamstring against the Mariners and went on the injured list the next day.

Left-hander Carlos Rodón, sidelined since spring training by a sore left forearm and an ailing back, was transferred to the 60-day injured list.
