"Here’s the reality, the 2019 Minnesota Twins are plenty talented. This team is good enough to challenge the Cleveland Indians for the AL Central division title, and they’re built to win a postseason series." I'm bullish on the '19 Twinkies, but this strikes me as wildly irrational optimism.
It really depends on the player and the setting, IMO. For me, that was a fantastic moment. If he had done that in a division game with the Twins down by 7 runs, it might play differently. I don't see this as a cocky move at all, just more La Tortuga goodness.
