Erik Miller, a left-hander for the San Francisco Giants, is expected to emerge as a key player in the team's strength after sustaining a left elbow strain and poor underlying metrics in his sophomore season. Despite a 1.50 ERA over 30 innings, Miller's FIP, or fielding independent pitching, was 3.97 and his -2.47 discrepancy between his ERA and his FIP was the highest in the majors. Despite this, Miller believes he will be ready in time for the start of the season. The team's bullpen is facing significant challenges due to injuries and trades, with Camilo Doval and Tyler Rogers being traded to the Yankees and Mets respectively. The Giants' last major league appearance was on July 2 before he sustained a left arm injury.
