Mark Leiter Jr. of the New York Yankees and Dennis Santana of the Pittsburgh Pirates faced setbacks in salary arbitration, with Leiter being awarded $2.05 million instead of his requested $2.5 million, while Santana will earn $1.4 million compared to his $2.1 million request. The arbitration decisions reflect a broader trend, with teams winning three out of the last four cases. Notably, Mickey Moniak of the Los Angeles Angels successfully negotiated a $2 million salary against a higher request, while Alex Vesia of the Los Angeles Dodgers avoided arbitration altogether by agreeing to a $2.3 million contract.

The arbitration results for Leiter come off a mixed season where he posted a 4.50 ERA in 60 appearances, including a strong postseason showing. Santana's performance was also solid, with a 3.89 ERA over 62 appearances for the Yankees and Pirates last season. As the arbitration period continues, several players, including Brendan Donovan and Nathaniel Lowe, are slated for hearings, adding more intrigue to the offseason.
