Vin Mazzaro

Vincent Michael Mazzaro (born September 27, 1986) is an American professional baseball pitcher who is a free agent. He has previously played in Major League Baseball (MLB) for the Oakland Athletics, Kansas City Royals, Pittsburgh Pirates, Miami Marlins, and San Francisco Giants.

Early years
Mazzaro grew up in Rutherford, New Jersey, and attended Rutherford High School, where he led the team to two consecutive state championships.

Oakland Athletics
Mazzaro was drafted by the Oakland Athletics in the third round of the 2005 Major League Baseball Draft.

In December 2008, Baseball America named Mazzaro the #8 prospect in Oakland's organization.

Mazzaro made his major league debut on June 2, 2009 against the Chicago White Sox. He earned the victory after pitching $6 1/3$ innings without allowing a run.

Kansas City Royals
Mazzaro was traded along with minor league pitcher Justin Marks to the Kansas City Royals for David DeJesus on November 10, 2010. After starting the 2011 season with the Omaha Storm Chasers, he was recalled by the Royals to replace the injured Bruce Chen on May 10.

He surrendered 14 runs in $2 1/3$ innings in an emergency appearance out of the bullpen in a 19–1 loss to the Cleveland Indians at Kauffman Stadium on May 16, 2011. Besides setting a new franchise record for most runs yielded in a game, he became the first pitcher in the modern era (since 1900) to allow that many without pitching 3 innings. His 14 earned runs given up was also the most by a relief pitcher since Les McCrabb of the Philadelphia Athletics allowed the same amount in four innings in a 19–4 defeat to the Boston Red Sox on April 16, 1942. Originally scheduled to be the starter the following night, Mazzaro was optioned back to the Storm Chasers after the game. Mazzaro was called back to Kansas City on June 7 after Royals starting pitcher Sean O'Sullivan was placed on the disabled list. The following year, he finished the season with an overall record of 4–3 with a 5.73 ERA in 18 games, primarily in relief. On November 20, 2012, the Royals designated Mazzaro for assignment as they cleared room on the 40-man roster ahead of the Rule 5 draft.

Pittsburgh Pirates
On November 28, 2012, Mazzaro was traded to the Pittsburgh Pirates with first baseman Clint Robinson in exchange for right-handed pitcher Luis Santos and left-hander Luis Rico. Santos and Rico both pitched in the Dominican Summer League in 2012.

Mazzaro was designated for assignment on March 29, 2014, and assigned outright to the Triple-A Indianapolis Indians on April 8.

On May 26, 2014, Mazzaro was designated for assignment again in order for Brandon Cumpton to be called up. He elected free agency in October 2014.

Miami Marlins

Atlanta Braves
Mazzaro signed a minor league deal with the Atlanta Braves on July 10, 2015. He was assigned to the Gwinnett Braves.

San Francisco Giants
