I did a Google search and found this in the internets, posted by someone using a pseudonym: On Saturday, 10 August, 1985, while playing the Philadelphia Phillies in the City of Brotherly Love, the St. Louis Cardinals manager Whitey Herzog used a full 9 man lineup of left-handed batters. This was quite easy for Whitey to do, with 5 of these regulars being switch-hitters that were digging in from the left side. Jack Clark, the big right-handed bat on the squad, had been in the starting lineup the whole year up to this point, but was out of the order that day (his spot in the 4-hole was replaced by the veteran left-handed bat of Darrell Porter), and our pitcher, right-hander Kurt Kepshire, also batted left during his brief career. The only 4 full-time left-handed hitters in the order were the above mentioned battery of Porter and Kepshire, as well as The Ripper's replacement at first (lefty Mike Jorgensen) and right-fielder Andy van Slyke. The other five men in the lineup that day were the usual Runnin' Redbirds' switch-hitting starters: Vince Coleman, Willie McGee, Tommy Herr, Terry Pendleton and Ozzie Smith. Here was the batting order that day: 1. LF Vince Coleman 2. CF Willie McGee 3. 2B Tommy Herr 4. _C Darrell Porter 5. RF Andy van Slyke 6. 3B Terry Pendleton 7. 1B Mike Jorgensen 8. SS Ozzie Smith 9. SP Kurt Kepshire What was special about that game? Well, it was the second game of a doubleheader in Philadelphia that day, with the Cardinals winning both games to get to 23 games over .500 that year (65-42 when the day was done), but the second game featured the mirror image of the Cardinal lineup in the first match. What did Whitey's lineup in the first game look like against Philly southpaw Jerry Koosman? That's right, he batted a full 9 from the right side: 1. RF Tito Landrum 2. CF Willie McGee 3. 2B Tommy Herr 4. 1B Jack Clark 5. LF Brian Harper 6. 3B Terry Pendleton 7. SS Ozzie Smith 8. _C Tom Nieto 9. SP Danny Cox That game featured the same switch-hitters (minus Vince), but also included straight right-handers Tito Landrum, Jack Clark, Brian Harper, Tom Nieto and pitcher Danny Cox. The Cardinals won the first game against lefty Koosman, 5-4, and the second game against right-hander Kevin Gross, 13-4. I love those switch-hitting teams. I thought this was a very interesting nugget.
