Mazzaro was recalled from Triple-A New Orleans on Saturday, MLB.com's Joe Frisaro reports.

He has long been transferred to being a reliever, and a fringy one at that. The Marlins placed two starting pitchers on the DL Friday, so once their rotation replacements are called up Mazzaro will likely be sent back to Triple-A.

Mazzaro was reassigned to minor league camp Tuesday, Joe Frisaro of MLB.com reports.

Despite posting solid numbers with the Pirates in 2013, Mazzarro spent most of last season at the Triple-A level. He's never had much luck piling up strikeouts, and he owns a career ERA of 4.69.

Mazzaro signed a minor league contract with the Marlins that includes an invite to spring training.

The right-hander owns a 4.69 ERA and 1.53 WHIP for his career, but he's gone 8-2 with a 2.89 ERA and 1.21 WHIP in 62 appearances with the Pirates over the past two seasons. Mazzaro will look to continue his National League success with Miami, though his inability to miss bats at a high clip (career 5.5 K/9) will likely keep him in the middle innings, if he even makes the roster.

Pirates sent RHP Vin Mazzaro outright to Triple-A Indianapolis.

Mazzaro accepted an outright assignment back in April, but it's possible he'll turn it down this time and declare free agency. The righty posted a 3.48 ERA over five relief appearances for the Pirates last month before being designated for assignment.

Mazarro had a 3.48 ERA in 10 1/3 innings with the Bucs. He was also designated for assignment in late March and made it through waivers unclaimed, but major league teams are more desperate for bullpen arms here in May.

Pirates recalled RHP Vin Mazzaro from Triple-A Indianapolis.

Mazzaro was designated for assignment by the Pirates at the end of spring training but elected to stay with the organization rather than test free agency. He now has an opportunity to run away with a mid-relief role.

Vin Mazzaro has accepted an outright assignment to Low-A Jamestown.

Mazzaro will join Triple-A Indianapolis soon. The Pirates are fortunate not only that the righty cleared waivers but that he decided to stick around in the organization rather than elect free agency. He'll provide some nice minor league depth.

Mazzaro surprisingly cleared waivers after being designated for assignment by the Pirates in late March. He has three days to accept or reject the minor league assignment.

Pirates general manager Neal Huntington implied that the team is likely to trade reliever Vin Mazzaro.

"We've had conversations," Huntington said. "If he gets to the outright waiver process, it will be a surprise to us." Mazzaro was designated for assignment Saturday after he failed to make the team out of spring. He had a strong 2013 season, and it's not surprising that teams looking for relief help would call on the 27-year-old.

Mazzaro posted a steady 2.81 ERA, 1.20 WHIP, and 46/21 K/BB ratio in 73 2/3 innings last season, but the Pirates have a loaded bullpen and simply couldn't find room.
