STILLWATER — The sterling silver thumbprint hangs from a chain around Andrew Rosa's neck, a small but powerful reminder.
In the fifth and final year of an embattled Oklahoma State baseball career, Rosa has every reason to look back on his time as a Cowboy with scorn and disappointment. Time on the bench, Tommy John surgery and a nagging bruise in his left heel hampered a future in the sport that once seemed so bright.
He keeps those unappreciative thoughts out of his head. He serves as a mentor and an example to younger teammates, a symbol of positivity.
