Alvarez isn't in the lineup for Thursday's game against the Cubs due to cramps, Anthony DiComo of MLB.com reports.
Alvarez felt cramping in his lower half toward the end of Wednesday's contest, so manager Carlos Mendoza decided to give him a day to recover Thursday. The skipper noted that Alvarez will be available off the bench, but it will be Luis Torrens behind the plate catching for starter Nolan McLean.
