Even as the Rockets’ playoff picture looks considerably brighter in the wake of their 10 wins in their last 15 games, a quick look at the schedule and a cursory look Tuesday around the Toyota Center practice court provided a timely reminder of the potential perils of April.

Forward Chandler Parsons sat at one end of the court, visibly drained from his participation in half of Tuesday’s practice after spending Monday in bed with food poisoning.

At the other end, James Harden was back at work after missing the last two games with an injured right foot. When he was done, he iced his foot down yet again before he and the team left Tuesday afternoon for a three-game road swing.

Both players hope to play Wednesday at Sacramento but said their condition at the pregame shootaround could be a deciding factor. Forward Carlos Delfino also sat out practice as a precautionary measure as he nurses a sore right foot.

Kings have got game … now

The schedule has potentially ominous overtones, too.

After Sacramento, the Rockets play Friday at Portland and Saturday at Denver — all locations where they lost during their most recent visits — as they try to hold on to the seventh spot in the Western Conference standings or move up to sixth.

Location, location, location means less to Rockets coach Kevin McHale than effort and consistent play down the stretch.

“I don’t care if we’re playing like Texas Tech, we’ve got to go on there and play,” he said. “We’re capable of a lot of ups and downs. Whether or not we won or lost in Sacramento (on the last trip), it’s the biggest game of the year.”

Since the All-Star break, McHale added, “Sacramento for whatever reason has played very well. They’re scoring the ball. They’re playing different. …They have more pace. They’re a handful.”

The Kings own victories over Chicago, the Los Angeles Clippers and Golden State since the trade in which the Rockets sent Patrick Patterson, Toney Douglas and Cole Aldrich to Sacramento in exchange for Thomas Robinson, Francisco Garcia and Tyler Honeycutt. Sacramento’s 109.6 points per game leads the NBA since the trade deadline.

“This is huge for us,” Parsons said. “It’s a good test, going on the road with three tough games in tough environments. It will be a good challenge for us to finish strong.”
