Olney High on Miller's Closer Potential

ESPN baseball analyst Buster Olney believes Mason Miller has the potential to develop into a top-tier closer for the Oakland Athletics. Miller, who showed promise in his rookie season, now faces the challenge of refining his skills to excel in high-leverage situations as a full-time closer.

The young pitcher will need to demonstrate consistency and composure under pressure to fulfill Olney's expectations as the Athletics look to strengthen their bullpen for the upcoming season.
