The oddities have already begun on the opening day of this year's Miami Open. In one of the first matches of the day, Christina McHale and Laura Siegemund didn't get far into their bout when Hawk-Eye Live had a bit of a moment.

In just the second game, McHale hit a first-serve long and the line-calling system let out a pretty loud boom. Hesitant to tee-up her second serve, the American paused and apparently Hawk-Eye wasn't finished causing a scene just yet.

The system continued to let out blaring and chaotic booms, causing he chair umpire to shake his head and shrug in confusion. Both McHale and Siegemund quickly retreated to the back of the court and waited out the glitch.

It didn't take long for things to resume to business as usual and McHale was granted a first serve.

Siegemund claimed the opening affair, 6-3, 7-5, to advance into the 1000-level event's second round. Before serving for the match a second time at 6-3, 6-5, the German took a medical time out and appeared to have a lower back issue.

The back injury didn't seem to affect her play, as she held at love to win the match. She will next face two-time major champion and Miami's No. 14 seed Victoria Azarenka.
