London, England (SportsNetwork.com) - Former finalist Juan Martin del Potro and Swiss slugger Stanislas Wawrinka were Mondays round-robin winners at the $6 million ATP World Tour Finals. The fourth-seeded del Potro was tested mightily by eighth seed Richard Gasquet before prevailing in the Day 1 nightcap, 6-7 (4-7), 6-3, 7-5, in 2 hours, 23 minutes. The tall Argentine broke for a 6-5 lead in the third set and then held his powerful serve to pickup the win. "Delpo" broke Gasquet four times, while the nifty Frenchman settled for two breaks in his first Tour Finals match in six years. The world No. 9 Gasquet corralled the final spot for this eight-man tournament last week. World No. 4 Andy Murray is missing the event after undergoing a recent back surgery. Meanwhile, making his debut at this lucrative event, the seventh-seeded world No. 8 Wawrinka knocked off sixth-ranked Tomas Berdych 6-3, 6-7 (0-7), 6-3 in 2 hours, 25 minutes at the prestigious season-ending event at Londons O2 Arena. The big-serving affair featured 27 aces, including 16 from the formidable Berdych. Wawrinka broke the fifth-seeded Berdych on two occasions and held his serve throughout on Monday. "My first impression was really, really nice to be here," Wawrinka said. "I saw that tournament so many times on TV. To win my first match here was something really special." This weeks four-player Group A features world No. 1 and U.S. and French Open champion Rafael Nadal, Roland Garros runner-up David Ferrer, the former Wimbledon finalist Berdych (0-1), and Wawrinka (1-0). Group B is comprised of Australian Open titlist Novak Djokovic, the former U.S. Open champ del Potro (1-0), 17-time Grand Slam winner Roger Federer, and Gasquet (0-1). The two-time champion Djokovic was last years big winner at The O2, beating the six-time Tour Finals champ Federer in the final. Djokovic and Federer are the only former champions in this years field. Nadal was the runner-up in 2010, Ferrer was the runner-up in 2007, and del Potro was a runner-up back in 2009. The hot Djokovic beat Ferrer in last weeks final at the Paris Masters and has won his last 17 matches overall. On Tuesday, Nadal will battle his third-seeded fellow Spaniard Ferrer and the second-seeded Djokovic will take on his sixth-seeded fellow former No. 1 Federer. Round-robin play will be staged through Saturday in London, with the semifinals on Sunday, and the final next Monday. The top-two players from each group will qualify for the semis.

Watch the Leafs vs. Avalanche live on TSN4 at 9pm et. The Maple Leafs also hope to rebound tonight after losing a 3-2 decision to Arizona on Tuesday. That snapped a three-game winning streak for Toronto and was the clubs first regulation road loss of the season (3-1-1). James Reimer made his second straight start in net, ending with 30 saves. However, he was beaten for a pair of goals in the first period and Toronto trailed by three before getting power-play tallies from Dion Phaneuf and Cody Franson. Terrible start and we just werent able to overcome it, said Toronto head coach Randy Carlyle. It seemed like we were in neutral and they were in third gear. Phil Kessel assisted on both goals, giving him a pair of tallies and six assists over a four-game point streak. He is tied for third in the NHL with 16 points. Bernier has faced the Avalanche just once before as a starter while also making a relief appearance against them. The Maple Leafs picked up their second straight win over the Avalanche with a 3-2 overtime victory at home on Oct. 14. Kessel scored the winner 34 seconds into the extra frame and Reimer finished with 22 saves. Toronto has won three straight in Colorado. Varlamov stopped 37 shots for the Avs in the teams 5-2 loss to the Vancouver Canucks Tuesday night. Stunned in the third period last time out, the Colorado Avalanche hope to rebound on Thursday night and avoid a fourth straight setback as they welcome the Toronto Maple Leafs to Pepsi Center. The Avs hosted the Vancouver Canucks on Tuesday and went up 2-0 on first- period goals by John Mitchell and Jamie McGinn, but the Canucks responded with five straight tallies, including four in the thhird period to hand Colorado a 5-2 loss.dddddddddddd Semyon Varlamov stopped the first 26 shots he faced, but ended up with 32 saves while allowing all five Vancouver goals. The loss dropped Colorado to 0-2-1 in its past three games and 3-6-5 on the season. I mean third period we are up a goal and end up losing 5-2. Its unacceptable to say the least, Mitchell said. We have to be better, we have to find a way. They come out and score a goal early, its 2-2. We cant come out and completely fall apart, you know, shut it down. We have to learn to respond and come out and play hard after that. We just didnt do anything and we certainly didnt help Varly. Colorado also lost defenseman Brad Stuart to a hamstring injury in the game and the ailment could sideline him for the next few weeks. Head coach Patrick Roy has opted to rest Varlamov tonight and will give Reto Berra his fourth straight of the campaign and first since Oct. 21. Berra has never before faced Toronto.
