Langeliers was placed on the paternity list Monday.
Langeliers was away from the team for Sunday's matchup and will now miss the next 1-to-3 days after being placed on the paternity list. Austin Wynns is expected to handle the catching duties until Langeliers returns, though the Athletics also landed Jonah Heim in a trade from Atlanta on Monday, so Heim could factor into the mix if he's elevated to the big-league roster.
