WASHINGTON — Alex Bregman has not stopped searching for answers. The veteran third baseman isn’t one to shy away from digging into video. He’s often staring at a screen, watching his movements in the cage or an old game, trying to figure out what’s right and what needs to be fixed.On Monday night while in his hotel room in the nation’s capital, the work continued with Cubs assistant director of MLB development Ben Martin. And perhaps a breakthrough was made.“Ben pulled up the KinaTrax data showing how my body is actually organized over the year when I load,” Bregman recently said. “We saw some pretty glaring differences, and we searched back to double-check it on video to watch that. Woke up in the morning thinking about it. Got here and went right to the cage trying to think about the same things we talked about. It’s been good.”“Good” may be an understatement. Tuesday, Bregman went 2-for-4 with a home run. Then Wednesday, he had his first real Cubs moment, slugging three home runs and driving in seven runs.Bregman had been on a bit of a run before those two games. He hit two home runs in the two games leading into the All-Star break. Going back further, he’s had a 159 wRC+ since June 29. But the start of the series against the Washington Nationals felt different.
