Miami, FL (SportsNetwork.com) - The Miami Marlins' roster looks a little different after the club made a flurry of transactions on Monday.
The promotion of top prospect Andrew Heaney from Triple-A New Orleans was the most notable move.
The ninth overall pick in the 2012 First-Year Player Draft, Heaney was 3-0 with a 2.74 ERA in four starts for New Orleans. The 23-year-old lefty began the season at Double-A Jacksonville, going 4-2 with a 2.35 ERA.
Outfielder Christian Yelich also was placed on the 15-day disabled list with a lower back strain, while pitchers Randy Wolf and Kevin Slowey were both designated for assignment.
Additionally, catcher Jarrod Saltalamacchia was transferred from the seven-day concussion list to the 15-day DL and infielder Donovan Solano was optioned to Triple-A New Orleans.
The Marlins have also recalled pitcher Anthony DeSclafani, infielder Justin Bour and outfielder Jake Marisnick from New Orleans.
Yelich, 22, is batting .259 with six home runs and 24 RBI over 63 games this season.
The 37-year-old Wolf joined the Marlins last month and went 1-3 with a 5.26 earned run average in four starts and two relief appearances.
Slowey, 30, was 1-1 with a 5.30 ERA in two starts and 15 trips out of the bullpen.
