Heard that Nina DeCesare won a trial for this position. She joined the BSO section in 2020. I’m not sure if other trials were awarded but I have been told that Baltimore’s CBA mandates trials before positions are awarded. I’m not aware of any other orchestra in which this is the case, very interesting approach.

San Francisco’s CBA also mandates a trial week.
