Some Pittsburgh Pirates fans are signing a petition to express their frustration following the team's decision to trade star outfielder Andrew McCutchen to the San Francisco Giants. As of Wednesday, more than 28,000 fans signed a petition on change.org asking Major League Baseball to force Pirates owner Bob Nutting to sell the team. Pittsburgh sent top starting pitcher Gerrit Cole to Houston on Saturday, then sent McCutchen to the Giants, shedding the organization of $20 million in salary in the process.
