Pete Alonso hit a ball so hard that even his Red Sox opposition was stunned

Pete Alonso is making a good case to earn the starting first-base job with the Mets this Spring. New York's No. 1 prospect smashed 36 homers between Double- and Triple-A last season and has been crushing the ball during Spring Training.

He may have topped himself on Saturday afternoon against the Red Sox.

In the top of the sixth inning, Alonso absolutely hammered Tyler Thornburg's offering up and over the 44-foot wall in left field.

It was so impressive that Xander Bogaerts interrupted himself while being interviewed to remark, "Wow, that was loud."

Yeah, that's no Spring Training wind-aided home run. That's serious power. Of course, while Alonso impressed the Red Sox, his fiancee's family may have been less enthused. After all, they're a family of Boston-based Red Sox fans.
