The Rangers' Adrian Beltre and the Angels' Andrelton Simmons were foes on Sunday in Anaheim, but they also became dance partners when Beltre found himself on second base in the eighth inning of the Halos' 3-1 win.
2. That hasn't worked since Little League
The Astros' Jose Altuve smacked a home run to lead off Sunday's game at Milwaukee, but he wasn't quite so successful when he tried to pull off the ol' hidden ball trick two innings later, following a double by the Brewers' Chris Carter.
3. A new pace of play rule?
Baseball has some complicated rules, but this is a pretty simple one: You need four balls to draw a walk.

Eventually, Kemp was called back and, to his credit, took the gaffe in good humor.

What, you thought Yoenis Cespedes wasn't going to enjoy his first home run of the season? The Mets slugger, in a throwback uniform, marked the occasion by celebrating with teammate Neil Walker.
