Four pitchers have not fully returned to practice and one might miss the season.

Pitcher Christian Pelaez’s freshman season is “in doubt,” coach Paul Mainieri said Monday. Palaez, from Miami, has suffered from a lingering shoulder injury and will need rehabilitation or surgery.

Sophomore Hunter Newman, suffering from a sore shoulder, was able to throw pain free, but his full return has been delayed, the coach said. Newman is in the running for a weekend starting spot.
