The Frontier League's all-time winningest pitcher, Aaron Ledbetter, will return to Washington for his final season of eligibility in the League.

The righthander has won 42 League games in his career and will be expected to ace a staff looking to win the club's first Frontier League championship after six seasons of playoff disappointment, including a Finals-series loss after sweeping games 1 & 2 AT Windy City last September.
