As US sports pundits ponder whether the NBA's Miami Heat or National Hockey League's Chicago Blackhawks are on the more impressive streak, players from each traded congratulation messages on Twitter.
Defending NBA champion Miami will try to stretch a club-record win streak to 17 games at home on Friday against Philadelphia after edging Orlando on Wednesday when superstar LeBron James made a layup in the dying seconds.
The Blackhawks will try to boost their club-record win streak to 11 games and NHL-best start to 25 games with at least a point on Friday when they visit the Colorado Avalanche, a club they beat 3-2 Wednesday on a last-minute goal.
After Wednesday's triumphs by both clubs, Heat scoring leader James posted a Twitter message to the NHL squad saying, "Hey Chicago Blackhawks, u guys are AWESOME!! #streaking".
Patrick Kane, the Blackhawks' leading scorer, replied with a tweet saying, "Back at you LeBron. Keep rolling."
Blackhawks left wing Bryan Bickell also took to Twitter in response, tweeting back to reigning NBA Most Valuable Player James: "Thanks for the support man. It's been pretty crazy."
The Blackhawks have not lost in regulation time over the first half of the lockout-shortened 48-game NHL season, a record for producing points in consecutive games to start an NHL campaign.
The 1979-80 Philadelphia Flyers went 35 games with at least a point in every game to set a league record that Chicago is now threatening.
That mark was set back when the NHL left regulation games ending level drawn. Now the NHL gives each team a point in the standings but plays over-time and a penalty shootout if needed to produce a winner in every contest.
If the Heat beat Philadelphia, they will match the longest win streak in the NBA this season, established by the Los Angeles Clippers. The NBA record win streak is 33 games set by the Los Angeles Lakers in the 1971-72 season.
The Heat seek back-to-back NBA crowns while the Blackhawks are trying to capture the Stanley Cup, symbolic of NHL supremacy, for the second time in four seasons.
