Pittsburgh Pirates rookie right-hander Jared Jones returned to the mound on Tuesday against the Chicago Cubs after a two-month absence due to a Grade 2 right lat strain. Despite showing healthy velocity, Jones struggled, allowing five runs over four innings, including two home runs. His return follows three rehab starts in Triple-A, where he had a standout performance in his final outing, striking out 10 batters in five scoreless innings. The Pirates have reinstated Jones and Carmen Mlodzinski from the 15-day injured list, and Jones is set to be a key part of the rotation as the team pushes for a Wild Card spot. Additionally, the Cubs' Miguel Amaya has been on a hot streak, significantly improving his performance since early July. Jones is expected to be on a limited pitch count as he continues to ease back into the rotation.
