I had some time to kill, so I thought it would be interesting to look at the Cardinals OF 4-man platoon so far (if you can call it a platoon):
Apr 6 (vs LHP Maholm): LF Duncan - CF Ankiel - RF Ludwick
Apr 7 (vs RHP Snell): LF Duncan - CF Ankiel - RF Rasmus
Apr 8 (vs LHP Duke): LF Rasmus - CF Ankiel - RF Ludwick
Apr 9 (vs RHP Ohlendorf): LF Duncan - CF Rasmus - RF Ludwick
Apr 10 (vs LHP Hampton): LF Duncan - CF Ankiel - RF Ludwick
Apr 11 (vs RHP Oswalt): LF Duncan - CF Ankiel - RF Rasmus
Apr 12 (vs LHP Rodriguez): LF Duncan - CF Rasmus - RF Ludwick
Apr 13 (vs LHP Davis): LF Duncan - CF Ankiel - RF Ludwick
Apr 14 (vs RHP Scherzer): LF Duncan - CF Ankiel - RF Rasmus
Apr 15 (vs RHP Garland): LF Duncan - CF Rasmus - RF Ludwick
Apr 16 (vs LHP Marshall): LF Duncan - CF Ankiel - RF Ludwick
Apr 17 (vs RHP Zambrano): LF Duncan - CF Rasmus - RF Ludwick
Apr 18 (vs RHP Dempster): LF Duncan - CF Ankiel - RF Ludwick
Apr 19 (PPD)
Apr 21 (vs LHP Perez): LF Duncan - CF Ankiel - RF Ludwick
Apr 22 (vs RHP Maine): LF Duncan - CF Ankiel - RF Rasmus
Apr 23 (vs RHP Hernandez): LF Rasmus - CF Ankiel - RF Ludwick
Apr 24 (vs RHP Dempster): LF Duncan - CF Ankiel - RF Ludwick
Apr 25 (vs LHP Marshall): LF Duncan - CF Rasmus - RF Ludwick
Apr 26 (vs RHP Harden): LF Rasmus - CF Ankiel - RF Ludwick
Apr 27 (vs RHP Jurrjens): LF Duncan - CF Ankiel - RF Ludwick
Apr 28 (vs LHP Reyes): LF Duncan - CF Rasmus - RF Ludwick
Apr 29 (vs RHP Vazquez): LF Duncan - CF Ankiel - RF Rasmus
Through 22 games:
Starts in LF: Duncan 19, Rasmus 3
Starts in CF: Ankiel 16, Rasmus 6
Starts in RF: Ludwick 17, Rasmus 5
Total starts for each guy: Duncan 19, Ludwick 17, Ankiel 16, Rasmus 14.
Rasmus has started roughly 3/5th of the team's games, not great but not terrible. La Russa is at least shuffling him in at each of the outfield spots on a semi-regular enough basis.
