Jazz Chisholm will be the Marlins opening day second basemen. He beat out Isan Diaz for the job.

Chisholm hit .268 with three homers and four stolen bases in spring training compared to Diaz who was just 2-34 this spring. Diaz will start the season in Triple-A Jacksonville.

“We look at Jazz as the every-day second baseman,” Marlins manager Don Mattingly said. “But this is the start of it. You’ve got to go perform and keep going every day.”

Chisholm was acquired from the Arizona Diamondbacks in a trade deadline deal in 2019 that sent Zac Gallen to Arizona.

“It feels great when everybody believes in you,” Chisholm said. “I know I already have a lot of confidence, but it gives you confidence to where it’s almost cockiness.”

Diaz was one of the prospects the Marlins acquired when they traded Christian Yelich to the Milwaukee Brewers following the 2017 season.

“We look at Jazz as the every-day second baseman,” Mattingly said. “But this is the start of it. You’ve got to go perform and keep going every day.”
