Belgium and Argentina head to Match Day Two in their Davis Cup semifinal all knotted up at 1-1 after Friday's singles rubbers. Belgium's David Goffin served as the leading force for his country by scoring the opening the day win over Federico Delbonis 7-5, 7-6 (3), 6-3.

Goffin's Consistency Pays Off
The semifinal started with Belgium's David Goffin in the opening rubber against Argentina's Federico Delbonis. Goffin put pressure on the Argentine's serve right away as he saw two break points in the opening game. Delbonis was able to fight those off as the pair would trade service holds to 2-2. In the fifth game, Goffin took advantage of a mounting pile of unforced errors from his counterpart as he saw four breaks points and converted the final one for a 3-2 lead. The Belgian would lose that lead by the eighth game as Delbonis broke back to even the set at 4-4. After swapping service holds, Goffin would craft another break point and pounce for a 6-5 lead. He closed the set out with a love service hold. Goffin's serving was a large key as the 15th ranked player on the ATP Tour won 81 percent of his service points compared to just 55 percent by Delbonis. The Argentine littered the court with 21 unforced errors in the first set.

Delbonis cracked immediately in the second set as Goffin secured a break on the third break point of the opening game. He would consolidate the break and take a 2-0 lead. Once more though, a loose service game that came out of nowhere would give the Argentine a chance to get back into the set in the eighth game. Goffin was broken at love. The Belgian said that his Argentine opponent amped up his game when he fell down a break, "Always when I was break up he was playing so good and was really aggressive so it was always tough to finish the sets."

Tied at 4-4, neither player would falter the rest of the way as the set went to a decisive tie breaker. The first seven points of the breaker saw each man hold his serve. On the eighth point, it was Goffin who scored what would be the key point to take a 5-3 lead. He would get close the set with a pair of winners for a 7-3 win in the tie break. The Argentine arguably played the better set with more winners, 17 to 15, and less unforced errors than Goffin.

The final set would start off well with Delbonis breaking Goffin, but he would give that break right back. Goffin seemed to sense the urgency to close the match as he broke Delbonis for fifth and final time in the match to go up 3-1. Goffin had several match points on Delbonis' serve with a 5-3 lead, but failed to convert any of the three break points he saw. The Belgian would not fail in his final service game as he sent Delbonis packing with an ace for the 7-5, 7-6 (3), 6-3 victory. After the match, Goffin credited the crowd with helping him to the finish line saying "It was a tough one but the atmosphere is always amazing here in Brussels,"

In all, Goffin was the more consistent performer on the night as Delbonis made 48 unforced errors and Goffin forced him into 20 more. Delbonis was able to win just 59 percent of his service points, while the Belgian won 71 percent on his serve.

Mayer Tries To Get Argentina Even In Second Singles Rubber
The second rubber matched Belgian Steve Darcis against Argentina's Leonardo Mayer. It was Mayer who put the pressure on the home standing Darcis with a solid serving display in the opening set. Mayer won 35 of 46 points on serve with eight aces, while Darcis struggled some to match. The Belgian gave out six break points in the set, but Mayer could not convert on any. Darcis failed on three attempts to break the Argentine's serve as the opener played out to a tie break. It was there that Mayer made his move and was able to close out the opener on his third set point to gain a 7-5 win in the tie break. Both men were a bit sloppy with Darcis making 24 unforced errors to 29 for Mayer. It was the Argentine's big and riskier ground strokes that paid off though with 27 winners to just 17 from the Belgian.

The second set played out much the same as Mayer was close to flawless on serve again. He won 28 of his 33 points on serve and did not allow Darcis a look at a break opportunity. Darcis again was able to match, but nearly got off to a poor start. Mayer had a look at three break chances in the opening game, but the Belgian came up big to save all three and hold. Nothing but service holds for both players all the way to a second set tie break. The Argentine would score the mini break to open the tie break and never look back as he rolled to a 7-1 win in the breaker and a two sets to love lead. The set again highlighted Mayer's grip it and rip it style as he made 22 unforced errors, but had 22 winners. That included six aces. Darcis made 14 unforced errors, but hit just nine winners. The Belgian did not get any cheap points off his serve either without any aces in the set.

Darcis Bites Back Briefly
With the rubber on the line in the third set, Darcis made an early move as he broke Mayer for the first time in the third game for a 2-1 lead. The Belgian would consolidate and then grab a bonus break as he raced to a 5-1 lead in the third set. Darcis showed a little bit nervy late in the set as he allowed Mayer to break back once, with the score going to 5-3 still in the Belgian's favor. Darcis would not waver in serving out the set to get on the board with a 6-3 win in the third. Mayer's serve was down a bit in this set with the Argentine winning just 57 percent of his service points. However, it was Darcis' ability to rev his game to a different level that stood out on top of that. Darcis scored 17 winners in the set while making just ten unforced errors.

The third set magic proved to be short lived for Darcis. After exchanging holds with Mayer through three games, the Belgian was broken in the fourth game as his inability to land a first serve proved crucial. Darcis only landed 46 percent of his first serves in play in the set, which allowed Mayer eleven looks at the Belgian's second serve. Mayer won seven points out of eleven from Darcis' second serve. The Argentine also got back to playing big on his ground strokes and finding the rhythm again as he blasted 17 winners in the set to just six for Darcis. The end result was a 6-4 win in the set as the match fell to Mayer 7-6 (3), 7-6 (1), 4-6, 6-3. For the match, Mayer's high risk-high reward style paid off with 81 winners, 24 of which came on aces. That helped mask 77 unforced errors. Darcis tallied just 49 winners and made 57 unforced errors. The Belgian's serve was not quite up to snuff as he landed just once ace all match.

Saturday's Doubles Rubber
Doubles becomes a critical component to determine which one of these countries will advance to the Davis Cup Final. Saturday's doubles tie was originally scheduled to pit Ruben Bemelmans and Kipper Coppejans together for Belgium. Carlos Berlocq and Diego Schwartzman were listed as the opponents from Argentina. The Belgians are likely to hold steady with their selections as neither Goffin nor Darcis is a great doubles player. Argentina though will likely go with at least one substitute. Expect Mayer to go into one of the slots. He could team with Berlocq again. Those two won their doubles rubber against Serbia back in July.
