The Dodgers and Padres are opening a three-game series at Petco Park on Friday night (GameTracker), and it looks like these two teams could be in for a very interesting weekend.

In the bottom of the first, Dodgers left Alex Wood had some words with Padres left fielder Jose Pirela, who was standing at second base following a leadoff double. Wood thought Pirela was stealing signs.

The Wood-Pirela exchange led to the two managers, Dave Roberts and Andy Green, getting into a heated argument.
