Alonso (hand) is out of the lineup for Wednesday's lineup against the Padres, Anthony DiComo of MLB.com reports.
Alonso had X-rays on his right hand come back negative after being hit by a pitch Tuesday, and he'll be forced to miss his first game of the season Wednesday. According to Dicomo, the 27-year-old is only dealing with some swelling in his right hand and is considered day-to-day. The Mets have a scheduled day off Thursday, so assuming it's not a serious injury, Alonso will have an extra day to rest up ahead of Friday's series opener against the Angels.
