Gibaut has struck out all six batters he's faced this spring, including the three he faced Wednesday against the A's.
Gibaut joined the Reds last year as a waiver claim from the Dodgers, who had previously claimed him from the Guardians. He mostly worked in low-leverage roles while appearing in 33 games with the Reds, striking out 48 batters in 34.2 innings, albeit with 18 walks and 38 hits allowed.
