All of the numbers, including their FedEx ATP Head2Head series (2-1 Nadal), suggest Rafael Nadal will advance to his 11^thBarcelona Open Banc Sabadell final on Saturday, when he faces fourth seed David Goffin in the semi-finals.

Nadal has won 17 consecutive matches and 42 consecutive sets on clay, dating back to his 2017 Rome quarter-final loss to Dominic Thiem. The Spaniard also didn’t drop a set against Goffin during their two clay-court FedEx ATP Head2Head matchups (2017 Monte-Carlo, 2017 Madrid). And Nadal has won 10 Barcelona Open Banc Sabadell titles.

But don’t be surprised if Goffin challenges and breaks at least one of Nadal’s streaks during their fourth FedEx ATP Head2Head matchup.

Goffin beat Nadal the last time they played, during a tight opener at the 2017 Nitto ATP Finals 7-6(5), 6-7(4), 6-4. So the Belgian should carry plenty of confidence onto Pista Rafa Nadal.

Goffin also doesn’t play your typical clay-court game. Instead of standing feet behind the baseline and going for long rallies, the Belgian tries to hug the baseline and take the ball early, which could apply some unique pressure to Nadal, who reached the semi-final with a 6-0, 7-5 win against Slovakia’s Martin Klizan.

Goffin’s road to his first Barcelona semi-final has been much more complicated. The No. 10 player in the ATP Rankings has lost the opening set in all three of his matches, but he’s ran away in each of the three deciders as well.

The scores of his deciding sets so far in Barcelona have been 6-2 vs. Marcel Granollers, 6-0 vs. Karen Khachanov and 6-2 vs. Roberto Bautista Agut. In other words, the Belgian is again showing the resiliency that helped him make his debut at the Nitto ATP Finals last year.

In 2017, Goffin led the Tour by winning 14 times after dropping the first set. His deciding-set record of 22-6 was also an ATP World Tour best. So far this season, according to his FedEx ATP Win/Loss Record, Goffin is 4-4 when losing the first set and 3-1 in deciding sets.

Roger Federer only just left Zambia after a visiting programmes supported by his self-named foundation this week. But he’s already looking forward to returning to the African nation.

Federer visited educational programmes and talked with students and parents who benefit from foundation-funded projects. He also made time for some fun, kicking around the football and dancing with boys and girls.

“The welcome here in Zambia has been wonderful. The people have been super, super, friendly. They could have not been nicer to me and to the team of the Roger Federer Foundation,” Federer said. “So when you feel this way, of course, you want to come back as soon as possible.”

Rafael Nadal endured his most serious test of the young clay-court season on Friday at the Barcelona Open Banc Sabadell. But the Spaniard fought through – coming back from a break down in the second set – to reach his 11^th Barcelona semi-final (11-1 in QF).

The No. 1 player in the ATP Rankings extended his clay-court sets win streak to 42 and his clay-court match-wins streak to 17 against Martin Klizan of Slovakia. Nadal saved three set points in the second set and ousted the left-hander 6-0, 7-5 on Pista Rafa Nadal.

The 31-year-old Spaniard, with a chance to play for his 11^th Barcelona title on the line, will next face fourth seed David Goffin, who beat Spaniard Roberto Bautista Agut 6-7(3), 6-2, 6-2. Goffin has come back from a set down in all three of his matches this week in Barcelona. Nadal leads their FedEx ATP Head2Head series 2-1, but Goffin won their most-recent contest at the 2017 Nitto ATP Finals.

Nadal dominated the opener against Klizan, breaking the left-hander three times and dropping only four points on serve (12/16). The Spaniard was racing all over the court and attacking the Slovakian, who had beaten Novak Djokovic and Feliciano Lopez of Spain to make the quarter-finals.

But in the second set, Klizan, a three-time clay-court titlist, found his form, breaking to start and mixing in drop shots against Nadal. At 5-4, Klizan had the set on his racquet.

That alone marked an accomplishment: Not since the 2017 Rome quarter-finals last May, when Dominic Thiem beat Nadal 6-4, 6-3, had someone won so many games against Nadal during a set on clay.

But Klizan couldn’t force a decider. Three set points came and went, and Nadal delivered a series of fist pumps and shouts after Klizan lifted a forehand wide on break point. The Spaniard raced through the final two games, prolonging his streaks and his stay in Barcelona.
