Mariners' Rollins finishing strong in AFL

Mariners' Rollins finishing strong in AFL

SEATTLE -- The Arizona Fall League wraps up play on Thursday, and lefty reliever David Rollins continues his strong finish for the Peoria Javelinas as he looks to enhance his chances of returning to the Mariners' bullpen in 2016.

Last year's Rule 5 Draft pick gave up four hits and two runs in two innings in his AFL debut in October, but since then has allowed just one run on four hits with seven strikeouts and two walks in 7 2/3 innings over his last eight appearances to lower his ERA to 2.79.

Rollins struck out the side in the seventh in Tuesday's 8-2 loss to Scottsdale.

The 25-year-old Texan was kept on Seattle's 25-man roster after being suspended the first half of last season, posting a 7.56 ERA in 20 appearances in his first Major League action after pitching in Double-A ball for the Astros.

With no Rule 5 protection remaining, he'll need to earn a roster spot to remain in Seattle's bullpen going forward, and he has three Minor League options remaining. Rollins is the No. 26-ranked Mariners prospect as rated by
