Seventh seed Garbine Muguruza defeated Marina Erakovic 7-5, 6-4 to reach the second round of the 2017 Australian Open, but the bigger concern was the Spaniard's health as a recurring thigh injury hampered her movement significantly.

Erakovic keeps pace, but Muguruza grabs late break to take the set

It appeared that the injury plaguing Muguruza wasn't affecting her early on as she opened with consecutive love holds. Surprisingly, Erakovic matched her and that run extended to midway through the set as the server took the first six games.

The Spaniard would draw first blood as she broke to 30 to take a 4-3 lead only to see the New Zealander break right back and it appeared Erakovic was poised to take the set as she held set point on the Roland Garros champion's serve.

Muguruza, now clearly hampered by the injury, saved the break point and she finally breached the Erakovic serve when she built a 0-40 lead. Erakovic saved the first break chance with a clear forehand winner, but she badly miss-hit that forehand on the next point to hand the Spaniard the break and a 6-5 lead. A hold to 30 gave the Spaniard the set despite being at less than full strength.
