Outfielder George Springer was not at Tuesday's workout because he awaits results from his latest coronavirus test.
Springer joins Alex Bregman as key Astros players forced to sit out a day of camp due to delays.
Last Wedneday, Bregman's delayed results kept him out of camp. Two days earlier, a lag in test results prompted the team to cancel workouts entirely.
Then on Saturday, a staff member potentially exposed to the virus meant the major league pitchers and pitching coaches would not attend camp Sunday.
Astros general manager James Click was asked Monday about whether Major League Baseball has provided direction on expediting test, and whether the team might use local resources to mitigate delays.
“I don’t think it’s lost on any of us, the logistical heft of this entire operation, the number of teams, the number of different cities, the number of different hoops that you have to jump through in order to get all of these things done. And inevitably there are going to be some hiccups and some speed bumps when you’re trying to create a new system on the fly and in short order.
“That said, having gone through a couple of these, you make the mistake once and hopefully you don’t make it again. And hopefully there will be fewer hiccups going forward.”
Springer hit a home run off Brandon Bielak in Monday's intrasquad game at Minute Maid Park. The Astros are set to play another Tuesday afternoon, with Justin Verlander and Lance McCullers Jr. taking the mound.
