“Bringing Mallex back home to Seattle is exciting for us all,” Seattle general manager Jerry Dipoto said in a statement. “His combination of speed, base running impact, defense and on-base abilities are unique in today’s game. We believe his breakout 2018 performance reflects the many ways his skills will positively impact the Mariners for years to come.”

Smith, 25, stole a career-best 40 bases this year and was caught 12 times. He hit .296, tied for the major league lead with 10 triples and had 40 RBIs. He is not eligible for free agency until after the 2022 season. He signed with San Diego in 2012, was traded to Atlanta in December 2014 and was dealt to the Mariners in January 2017 and sent to the Rays on the same day in a swap that sent left-hander Drew Smyly to Seattle.

Heredia, who turns 28 in January, hit .236 with 5 homers and 19 RBIs in 337 plate appearances as a fourth outfielder for the Mariners this year. He is not eligible for free agency until after the 2022 season.

Zunino, 27, was taken by Seattle with the third overall pick in the 2012 amateur draft and signed for a $4 million bonus. He hit just .201 this year but had 20 homers with 44 RBIs, down from a .251 average, 25 homers and 64 RBIs in 2017. Although well-regarded for his defense, he has struck out 310 times in 760 at-bats during the past two seasons.

Zunino grew up in Cape Coral, Florida, and played for the University of Florida. He made $2,975,000 this year, is eligible for salary arbitration and can become a free agent following the 2020 season.

Seattle also sent minor league left-handed pitcher Michael Plassmeyer to Tampa Bay and the Rays sent minor league outfielder Jake Fraley to the Mariners.
