Ketel Marte is returning fire at his critics this week.
The Arizona Diamondbacks star second baseman Marte took to Instagram on Tuesday with a notable post. He reposted an image of himself celebrating with teammate Corbin Carroll during a game last season.
“Not Good teamate [sic],” Marte wrote, along with some smiley-face emojis.

Marte, a three-time All-Star at 32 years old, was clearly responding to the rumors that dogged him during the 2025 season of alleged bad teammate behavior. Most notably, Marte took an unpaid leave of absence in the second half of the year after his home was burglarized during the MLB All-Star Game. While Marte later ended up apologizing for doing so, a report claimed that Marte had caused frustration among his Arizona teammates with his time off (read the full details here).
This winter, we have heard that the Dbacks are supposedly motivated to trade away Marte (though that may be more based on certain financial motivations than the clubhouse dynamic). The Boston Red Sox, once seemingly a frontrunner to trade for Marte, are now less likely to do so in the wake of acquiring another infield power hitter in Willson Contreras earlier this month. That said, some interesting suitors are still very much in the mix for Marte.
Marte, who hit .283 with 28 home runs and 72 RBIs over 126 games last season, is making roughly $17 million per season through 2030 and has an $11.5 million option for 2031 as well. As the longest-tenured Dbacks player who has been with the team since 2017 and has been in Major League Baseball since 2015, Marte clearly feels that he deserves more slack than he is getting right now.
