With the season opener less than a week away, it would seem likely that Gregerson, who was hobbling a bit Friday, would be placed on the 10-day disabled list and that both Mayers, who will start Saturday against the New York Mets, and Brebbia would be on the club when it starts play Thursday in New York.
Munoz, who is hitting .365 with pop and has surprising defensive ability, is valued because the Cardinals will keep only four reserve players. He was in left field Friday but has starred at shortstop and also has played center field, right field and second base, with Matheny strongly on record as saying Munoz also could be an outstanding defensive third baseman.
