The Cardinals announced an outfield roster switch this morning. Harrison Bader is headed to the 10-day injured list with a hamstring strain while Lane Thomas will join the active MLB roster for the first time.

Bader’s placement is retroactive to April 14th, so he’ll be sidelined through at least the 23rd. There’s no indication to this point that he is dealing with a significant injury, but it was obviously enough of a tweak to require a dedicated period of rest. Bader, the club’s regular center fielder, joins fellow outfielder Tyler O’Neill on the shelf.

That combination of injuries has opened the door for Thomas. After a 2018 upper-minors power outburst, the 23-year-old was added to the 40-man roster last fall to protect him from the Rule 5 draft. He’s off to a .229/.383/.286 start through 47 plate appearances at Triple-A this season.
