Diamondbacks star spotted at casino during team's game after no-showing to stadium earlier in the week

Ketel Marte and Vladimir Guerrero Jr. hit BACK-to-BACK home runs to extend the Dominican Republic's lead over Venezuela.

Arizona Diamondbacks star Ketel Marte’s strange week took another turn on Friday.

Marte began his week by failing to show up to Fenway Park for the team’s game against the Boston Red Sox on Monday and was scratched from the lineup minutes before first pitch. He was then placed on the restricted list and seemingly had no contact with the team until Thursday.

On Thursday, Marte and team officials reportedly had a lengthy meeting, after which the Diamondbacks placed the 32-year-old on the injured list with left knee inflammation.

On Friday, while the Diamondbacks were playing the Cincinnati Reds at Chase Field, Marte was spotted by fans gambling at Talking Stick Resort, a casino. In one video, Marte is shown at the tables while the Reds-Diamondbacks game was on a TV nearby.

Diamondbacks manager Torey Lovullo was asked about Marte’s casino run after the team’s 9-0 win.

"He’s free to do whatever he wants," Lovullo told reporters postgame. "That’s how I look at it. As long as he wakes up tomorrow morning and posts, and gets his work done at Salt River, which I am certain he will, that’s all that matters to me right now."
