The team's commitment to contend was complete when Green made a midseason deal on June 15 to shore up the starting rotation due to injuries to Rick Reuschel (5–5) and Sanderson. The deal brought 1979 NL Rookie of the Year pitcher Rick Sutcliffe from the Cleveland Indians. Joe Carter (who was with the Triple-A Iowa Cubs at the time) and center fielder Mel Hall were sent to Cleveland for Sutcliffe and back-up catcher Ron Hassey (.333 with Cubs in 1984). Sutcliffe (5–5 with the Indians) immediately joined Sanderson (8–5 3.14), Eckersley (10–8 3.03), Steve Trout (13–7 3.41) and Dick Ruthven (6–10 5.04) in the starting rotation. Sutcliffe proceeded to go 16–1 for Cubs and capture the Cy Young Award.
