Neal signed a minor-league deal with the Rockies on Thursday, according to his representation at MSM Sports.
Neal has played the last three season in the Nippon Professional Baseball league with the Seibu Lions. He worked exclusively as a reliever and maintained a 4.85 ERA to go along with only 185 strikeouts across 337.2 innings. Neal will have the chance to earn a bullpen role in Colorado, though even if he sticks with the team he isn't likely to serve in a high-leverage role.
