The Cubs had planned on carrying 13 pitchers, but instead placed lefty Brian Duensing on the 10-day disabled list to give him time to build up arm strength after missing time in camp because of back spasms. They'll start the season with 12 pitchers and carry both La Stella, who does have options left, and Szczur, who does not.
La Stella batted .270 in 13 Cactus League games, and provides a left-handed bat off the bench.
