The Cardinals will use a rookie pitcher in Tuesday's start against the Reds, but the club hasn't decided whether Michael Wacha, Tyler Lyons or Carlos Martinez will be tabbed as the start, MLB.com reports.
All three pitchers will join the Cardinals Tuesday after the minor-league regular season ends. Martinez struck out nine while allowing just one earned run in seven innings in his Triple-A start Thursday. Lyons pitched two innings in relief for Triple-A Memphis Friday, striking out two without allowing a hit or a walk. Wacha pitched four scoreless innings in relief Wednesday for the Cardinals, striking out seven while walking one.
