Acuna went 2-for-3 with a walk, a double and a solo home run in Saturday's 6-3 win over the Phillies.
The 22-year-old has been on fire since getting promoted last weekend, batting .385 (10-for-26) in his first eight big-league games with six extra-base hits, including three homers. Acuna's power display is especially impressive considering he hit only seven home runs in 131 games at Triple-A this season. Francisco Lindor (back) should return to the lineup any day now and reclaim the starting job at shortstop, but with a playoff spot on the line, the Mets could keep Acuna's red-hot bat in the lineup at another position.
