Houston sports fans may look back at Tuesday, Aug. 18 as the day the Astros became legit pennant contenders, and the Rockets took their first serious step toward the 2020 NBA title.

The Astros beat the Colorado Rockies, 2-1, in extra innings, and the Rockets unleashed a wire-to-wire beatdown on the OKC Thunder, 123-108, to take Game 1 of their first-round playoff series.

Sure, call me a bigger homer than that hack who wrote the Iliad and the Odyssey, but don't be surprised if we have two socially distanced parades around the corner in downtown Houston.

So far, the NBA playoffs have been a showcase for big-time superstar scorers, like Damian Lillard, Luka Doncic, Anthony Davis, Giannis Antetokounmpo, LeBron James, Donovan Mitchell and … our guy James Harden.

Who has the edge? Listen to Charles Barkley: "James Harden is the best one-on-one player I may have ever seen in my life." And Barkley has seen Michael Jordan, Kobe Bryant, LeBron James, all the legends. Rockets general manager Daryl Morey said it last year: "You can argue for him (Harden) as the best offensive player of all-time."

Harden poured in 37 points Tuesday to lead the Rockets to a statement win over the OKC Thunder. Yeah, there are games when he has more turnovers than Three Brothers Bakery, and more missus than Larry King, but when he's on, nobody tops Harden. Don't forget, this scoring machine led the NBA in assists in 2016-17. He's averaged more than seven assists a game the past six seasons.

Things will only get better when Harden's superstar running mate Russell Westbrook returns from a quad injury. Eric Gordon already is back in form. Add in Danuel House, Robert Covington, Jeff Green, Ben McLemore, P.J. Tucker and Austin Rivers, and the Rockets simply are too fast and have too much firepower for an opponent to handle.

Tuesday, the Rockets overwhelmed the Thunder, led 68-52 at halftime and didn't let the Thunder get within single digits the rest of the game. The Rockets were scary good.

Earlier that day, and just as important, the Astros won a game they would have blown two weeks ago. Starter Zack Greinke was magnificent, tossing eight innings of shutout ball. Light-hitting Myles Straw lined a bases-loaded walk-off single in the 10^th for the 2-1 Astros win. It was their fourth consecutive one-run victory. That's what champions do, win close games.

It's not just how the Astros are winning, it's with whom they're doing it. Monday, six of the nine hitters in the Astros batting order were hitting .200 or below: George Springer, Abraham Toro, Jose Altuve, Kyle Tucker, Dustin Garneau, and Straw. The starting pitcher was rookie Brandon Bielak. Somehow they beat the Rockies, by the same 2-1 score.

Justin Verlander, George Springer (here we go again), Roberto Osuna, Yordan Alvarez, Brad Peacock, Aledmys Diaz, Michael Brantley, and Chris Devenski are on the infirmary list. Joe Smith has an excused absence for the season, but Osuna and Alvarez likely won't return this year.

Yet here they are, with a 13-10 record, riding a six-game winning streak, firmly in second place in the American League West. By this time next week, half the season will be over, that's weird, and the Astros are in the thick of the playoff picture.

Think back to last year, when the Astros won 107 games and the American League pennant. The Astros began the 2019 season with a pitching rotation of eventual Cy Young Award winner Verlander (21-6), Cy Young runner-up Gerrit Cole (20-5), lefty Wade Miley (14-6), and righty Peacock (7-6). Between them, they started 115 games for the American League champion Astros. That's a pennant-winning staff.

This year, all gone: Verlander is 1-0, on the injured list. Cole is 4-0, but for the New York Yankees. Miley is 0-2 with a 16.20 earned run average for the Cincinnati Reds. Peacock is nursing a shoulder injury and hasn't pitched this season.

In 2020, the Astros are relying on pitchers Greinke and the return of Lance McCullers. After that, it's not a who's who, it's just a "who?" The Astros are throwing pitchers wearing uniform No. 59 (Framber Valdez), No. 60 (Enoli Paredes), No. 53 (Cristian Javier), No. 70 (Andre Scrubb), No. 67 (Cy Sneed), No. 64 (Brandon Bielak), No. 72 (Humberto Castellanos) and No. 66 (Bryan Abreu).

That isn't a pitching staff. That's the Houston Texans offensive line. Still, right now, I wouldn't bet against Houston – the Astros or the Rockets.
