Wheeler (elbow) was placed on the 15-day disabled list Friday.
After missing the entire 2015 season, Wheeler is nearing the end of his recovery from Tommy John surgery. The 25-year-old went 11-11 with a 3.54 ERA in 2014, and although he will likely miss the first couple months of the season, he will have the opportunity to compete for the fifth spot in the rotation with Bartolo Colon once healthy.
