WATCH: Nadal breezes past Groth on wild day for umpires

On Day 2 of the French Open, Rafael Nadal started on his march for a tenth title by sweeping past Sam Groth, 6-1, 6-1, 6-1. The score line, though straightforward, gave the Spaniard opportunity to show off some tweener talent:

Other men's matches provided a lot more drama. Nicolas Almagro got into a heated argument (in Spanish) with chair umpire Carlos Bernardes (him, again?!). The emphatic conversation lasted more than five minutes after Almagro won the match (he beat Philipp Kohlschreiber, 5-7, 6-2, 6-2, 6-4).

At one point in stating his case, Almagro reached for the name drop. "Andy Murray," Almagro said. "He can say what he wants, nothing happens," and then he imitated Murray swearing repeatedly.

The name-drop tactic is nothing new. In 2014, Dmitry Tursnov referred to Nadalduring a debate with the umpire over time violations. Nick Kyrgios also name-dropped Nadal during a code violation argument in Miami, and recently made more claims of the sport being biased by bringing Novak Djokovic into the mix.

In another first-round men's match, Santiago Giraldo was embroiled in what would end up being a four-hour, five-set marathon with Paul-Henri Mathieu. Mathieu called for a medical time out in the middle of a game in the third set, which ignited long-lasting tension:

At one point, chair umpire Marijana Veljovic had to step in, literally:

Mathieu pulled out the win, 6-4, 6-7 (2), 6-4, 1-6, 6-3 just as dusk was closing in on a busy, busy day for chair umpires in Paris.
