The Astros officially kicked off their new era under new management Monday when pitchers and catchers took the field at Osceola County Stadium for the first workout of Spring Training. Astros manager Brad Mills said everything went as smoothly as could have been expected, as 28 pitchers and seven catchers put in a few hours of work for the first time as a group.

Perhaps the best news for the Astros as they hit the field was that everyone is healthy, including catcher Jason Castro and Brandon Lyon. Castro missed all of last year and Lyon sat out most of the year following surgery.

“I was pleasantly surprised to see the guys in great shape,” Mills said. “The guys did a lot of things this off-season [to stay in shape]. With a lot of new players and a lot of new staff, it was good. I thought they did a good job. Yeah, there are some things they have to tighten up a little bit, but for the most part I thought it was real good.”

The pitchers are broken into six groups, with three groups throwing in the bullpen each day. Among those getting on the mound Monday were J.A. Happ, Jordan Lyles, Brett Myers, Zach Duke, Wesley Wright and Henry Sosa.

The position players won’t work out as a group until Sunday. Among those who showed up at camp Monday were Jordan Schafer, Jose Altuve, Chris Johnson, Jed Lowrie, Jimmy Paredes, Brett Wallace, Brian Bogusevic, Jack Cust, Jake Goebbert, J.D. Martinez, J.B. Shuck and George Springer.
