Andres Torres and D.J. Carrasco began their rehab assignments on Monday night with Class A St. Lucie.
Torres suffered a strained left calf on Opening Day. Carrasco sprained his right ankle during spring training.
With Torres potentially coming back soon, it could mean that Kirk Nieuwenhuis' tenure with the major league team is on the clock.
Carrasco had a scoreless, eight-pitch inning that included one strikeout.
Torres played six innings in center field. He went 3-for-4 with an RBI and two runs scored. He also stole two bases.
