Input: Read this: 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.

Input: Read this: Accounts of the use of leeches for the medically dubious practise of blood-letting have come from China around 30 AD, India around 200 AD, ancient Rome around 50 AD and later throughout Europe. In the 19th century medical demand for leeches was so high that some areas' stocks were exhausted and other regions imposed restrictions or bans on exports, and Hirudo medicinalis is treated as an endangered species by both IUCN and CITES. More recently leeches have been used to assist in microsurgery, and their saliva has provided anti-inflammatory compounds and several important anticoagulants, one of which also prevents tumors from spreading.
