Through a nine-year major league career that has included hundreds of teammates, Travis Jankowski cannot think of many better.

The Rangers outfielder spent only one season with the Mets, but he was around the club from spring training last year until the end of July and came away thinking that Pete Alonso “is one of the best” teammates he has ever had.

“He is probably an all-time great clubhouse guy,” Jankowski said this week. “What he does just for that clubhouse — the mentality he brings, where he has the goofiness to him but also the professional demeanor about him. He knows when to be goofy. He knows when to turn the switch on and say, ‘Hey, it’s go time, let’s win one tonight.’

“That’s something that you can’t quantify. … I was the new guy. [Alonso] making me feel welcome speaks volumes not just to me, but I’m sure to everyone in that clubhouse.”
