Alvarez went 1-for-3 with a walk, a solo home run and a second run scored in Sunday's win over the Pirates.
The backstop took Kirby Yates deep in the fifth inning, giving the Mets a 10-1 lead. Alvarez has gone 16 straight games without collecting multiple hits, but he's drawn 14 walks during that stretch to fuel a .224/.406/.408 slash line with three doubles, two homers, five RBI and eight runs.
