Cohen Williams "Laddie" Renfroe (born May 9, 1962) is a former Major League Baseballpitcher. He pitched in four games with the Chicago Cubs in 1991. Renfroe pitched with a sidearm delivery and appeared primarily as a relief pitcher and closer throughout his nine-year professional career.
After three seasons in Class-A ball, Renfroe split both the 1987 and 1988 seasons between the Double-A Pittsfield Cubs and Triple-A Iowa Cubs. Pitching for the Double-A Charlotte Knights of the Southern League in 1989, he led all minor-league pitchers with 19 wins, and won the Southern League Pitcher of the Year award that season.[4] He was promoted back to Iowa in 1990, and spent the following three seasons with the club.
He was called up to the Chicago Cubs on July 2, 1991,[4][5] and made his Major League debut the following day at Wrigley Field against the Pittsburgh Pirates. He ultimately appeared in four games as a relief pitcher with Chicago, finishing with a 0–1 win–loss record and a 13.50 ERA. He returned to Iowa on July 25.[6]
In September 1992 as a member of the Iowa Cubs, he was injured when struck in the head by an errant baseball.[7] The resultant head trauma caused him speech and vision problems,[4] and he retired thereafter, in part because of sustained complications from the injury.[4]
