Seattle Mariners prospect Jesus Montero didn’t do himself any favors at spring training when he arrived 40 pounds overweight. He also was suspended for 50 games last season as part of the Biogenesis scandal after playing in 29 games for Seattle.

Thursday night, he may have hammered the final nail into his own coffin, so to speak. With a baseball bat, no less.

Montero had joined the short-season Class A Everett AquaSox for a rehab assignment after spending much of the season with Class AAA Tacoma. The AquaSox were in Boise for a game Thursday, with a yet-to-be identified Mariners cross-checker — a roving scout who keeps tabs on a team’s prospects — in attendance.

Take it away, Tyler Maun of MiLB.com:

Montero was coaching first base, and at the end of an inning, the unidentified cross-checker yelled at him to hustle off the field, according to Boise official scorer Liza Safford. Montero then headed to the AquaSox dugout on the third-base side.

According to a game offical, the cross-checker then ordered an ice cream sandwich and had it sent to Montero in the dugout, escalating the confrontation further. The official said Montero — who arrived at Mariners Spring Training 40 pounds overweight this season — approached the stands with a bat while screaming profanities and threw the sandwich at the cross-checker. Montero had to be pulled back from the stands by Everett pitching coach Nasusel Cabrera, Safford said.

Montero was not ejected from the game and remained in the AquaSox dugout until it was completed, the game official confirmed.

Mariners GM Jack Zduriencik told the Seattle Times that the Mariners franchise was keeping tabs on things, but otherwise had little else to say: ” “I am aware of the incident in Boise. We are currently in the process of gathering information, but until I have all the details, I cannot comment.”

No details have been released about the ultimate fate of the ice-cream sandwich.
