After three rehab games in High-A Frederick, Machado’s Orioles season debut was pushed back twice because of rain. He said he continued to prepare during the two days, and he looked forward to ending the wait.

“Just because it was raining out there doesn’t mean you couldn’t be working,” Machado said. “I’ve got one or two butterflies in there, but it’s just part of the game. It’s just another game out there, but it’s going to be my first one. I’m excited for it.”

Lombardozzi optioned to Triple-A

To make room for Machado on the 25-man roster, the club optioned infielder Steve Lombardozzi to Triple-A Norfolk.

Lombardozzi, who was acquired in March in a trade that sent infielder Alex Gonzalez to the Detroit Tigers, batted .292 with two RBIs and six runs scored in 19 games. He didn’t walk at all and struck out 13 times in 72 at-bats while playing solid defense.

“I got to tell you, in the past some years, we have sent guys out, and it’s pretty cut and dried,” Showalter said. “But the last two or three [moves], I hope that’s an indication of better depth.”

Ultimately, the Orioles chose to keep Jemile Weeks, who made his Orioles debut April 26, instead of Lombardozzi. Showalter said he expects to see Lombardozzi again this season.
