After becoming one of the breakout stars of the D-backs system this season, Mitch Haniger is on the move again.

Arizona sent its 21st-ranked prospect, along with big league shortstop Jean Segura and left-hander Zac Curtis, to the Seattle Mariners in a five-player trade for right-hander Taijuan Walker and infielder Ketel Marte.

Selected 38th overall in the 2012 Draft by the Brewers, Haniger was shipped to the D-backs at the 2014 Trade Deadline for outfielder Gerardo Parra. After hitting .310 with 13 homers in his first season in the organization in 2015, the 25-year-old outfielder broke out this year. He posted a .321/.419/.581 slash line with 25 homers and 94 RBIs in 129 games between Double-A Mobile and Triple-A Reno en route to garnering the D-backs' Minor League Player of the Year award and earning a spot among their 2016 Organization All-Stars.

Haniger made his Major League debut on Aug. 16 and hit .229/.309/.404 with five homers and 17 RBIs in 34 games for the D-backs. He's 14th among Mariners prospects by MLB.com.

Curtis compiled a 3.90 ERA and 52 strikeouts over 30 innings across two Minor League levels this season. Promoted directly from Class A Advanced Visalia at the end of April, the 24-year-old southpaw went 0-1 with a 6.75 ERA over 13 1/3 innings in 21 Major League appearances.

"We see Haniger as a high-ceiling prospect who projects to join our outfield as soon as next season," Mariners general manager Jerry Dipoto told MLB.com, "while Zac Curtis' track record in the Minors gives us great confidence in his future as a big league pitcher."

The lone big league piece acquired by the Mariners, Segura produced a breakout season for the D-backs after coming over from the Brewers in a January trade. The 26-year-old infielder hit .319 and set career highs with 20 homers and 64 RBIs in 153 games with Arizona. He also tied for fifth in the National League with 41 doubles and stole 33 bases in 43 tries.

In return, the D-backs received two of the Mariners' young big leaguers. Walker, 24, was Seattle's top-ranked prospect as recently as the end of the 2013 season. Selected 43rd overall in the 2012 Draft, he went 8-11 with a 4.22 ERA and 119 strikeouts over 134 1/3 innings in this year. Marte, 23, signed with the organization as a free agent out of the Dominican Republic in 2010 and batted .259 with 11 steals in 119 games at shortstop this season, despite landing on the disabled list twice with a sprained left thumb and mononucleosis.
