Rodriguez says Anderson felt Flores was stealing signals from first base during Anderson’s pitching start on Monday. Anderson allowed five runs on seven hits and two walks over 4.1 innings in Monday’s 7-6 win over the Red Sox.

Since Anderson is a lefty, Flores would have had a good view of where Anderson was placing his hands and the ball, and could have helped him pick up any pitch-tipping tendencies.

There is nothing illegal about picking up signs or deciphering if an opponent is tipping pitches. It’s only illegal if you use technology during the game as a means to help break the signs or communicate those picked up signals.

The Red Sox wound up winning Wednesday's game, 11-9, on the shortest walk-off home run you’ll see.
