"I don't know if there was a key, we were both playing very even tennis", Shapovalov said. "It's not a moment for excuses".
"The sliding and running in the last two matches, I began to feel it against (Elise) Mertens and it grew with every day".
However, the 2002, 2013 and 2015 Roland Garros champion hinted she was undecided after organisers insisted that all players stay in tournament hotels.
"I know it's very hard". "Hopefully I'll be able to raise that level for the French Open because that's going to be necessary if I want to go deep in the tournament". Nadal, a 12-time Roland Garros victor, lost in the quarter-finals of the Italian Open to world number 15 Diego Schwartzman.
Watched by a crowd of about 1,000 socially distanced fans, Djokovic got off to a poor start against Argentine eighth seed Schwartzman, finding himself two breaks down at 3-0 as the rain fell in Rome.
Djokovic, meanwhile, let his frustrations spill over in a two-hour battle with his 97th-ranked German rival.
That infamous default came after he struck the ball at a line judge during his fourth-round match against Pablo Carreno Busta in NY this month. "I'll probably do it again". I don't want to say impossible, because it's not impossible. "That's how I guess I release sometimes my anger".
Schrwartzman shocked nine-time Rome victor Nadal, the two-time defending champion on Saturday, in the tune-up event ahead of the French Open in Roland Garros.
The 33-year-old next plays Norway's Casper Ruud who also needed to fight to get past Italian fourth seed Matteo Berrettini 4-6, 6-3, 7-6 (7-5).
Djokovic came out on top in a very tight, high-quality first set in windy conditions after going a break down to the Norwegian clay-court specialist in game three.
The 34-year-old arrives a little under-cooked with a quarter-final exit in Rome last week prompting speculation that a dethroning is imminent. "I'll do some homework and be ready for that one". "Since then I started to play really well and finally, after two finals, I could win this title".
Berrettini's elimination ended home hopes in the tournament which will be open to 1,000 spectators from Sunday's semi-finals.
As for Halep, she can approach the French Open with confidence having not lost a match since the Australian Open semifinals in January.
"One, it's winning a tournament like this".
Halep reached her third Rome final by beating Garbine Muguruza 6-3, 4-6, 6-4 to improve her record in tennis' restart to 9-0.
Former world No. 1 Plisokva later said she had an eye on the French Open as she withdrew due to injury for the first time in her career.
Halep, who skipped the US Open amid coronavirus concerns, had twice finished runner-up in Rome.
