Del Potro suffers emotional loss in possible last match of his career in Buenos Aires

After a two-year battle with injury, Juan Martin Del Potro made his return to the court at the Argentina Open but fell to compatriot Federico Delbonis in a highly emotional match.

Despite his best attempts, the former World No.3 was unable to get past his good friend, as Delbonis secured a 6-1 6-3 victory. The crowd on Court Guillermo Vilas was thrilled to have the 2009 US Open champion back on the court, with fans singing his name at every opportunity. This wasn't done out of disrespect to Delbonis, but rather out of love and appreciation for Del Potro, who had considered retirement but fought to overcome his nagging injuries.

Although his heart was still in it, the Tower of Tandil lacked the mobility to move around the court as freely as he would have liked. Struggling to keep balls in play, Del Potro relied on his forehand for most of the match, which still showed signs of explosive power. However, his limited movement and rust was very apparent, as Delbonis cruised through the first set.

Showing his championship spirit, Del Potro fought back in the second set, keeping the score even at 3-3. However, after a particularly long game, the Argentine was finally broken as Delbonis raced to a 5-3 lead. It was at this point that Del Potro was overcome with emotion, pausing before he served for possibly the last time on the ATP Tour. The 22-time ATP titlist buried his face in his towel, shedding tears along with the entire stadium, who nonetheless erupted in singing his name. After regaining composure, Del Potro served but was unable to hold serve, sending a forehand long and handing Delbonis the match.

The US Open champion hinted at retirement before the tournament, and is currently scheduled to compete at the Rio Open. However, based on his actions on the court, this could very well be the final match of his career.
