Mets top prospect Smith delivers 4-for-4 night

First baseman propels Class A Savannah to walk-off win, extends hit streak to 6 games

First baseman Dominic Smith, the Mets' No. 3 prospect, collected four hits Tuesday and helped Class A Savannah rally to defeat Charleston, 9-8, in walk-off fashion.

Smith, ranked No. 88 on MLBPipeline.com's Top 100 Prospects list, finished the night 4-for-4 with a run and a walk. It was his first four-hit game of the season and extended his hitting streak to six games.

After leading much of the night, Savannah gave up three runs in the top of the ninth and entered the bottom half of the inning trailing, 8-6. Two errors allowed them to tie the game with one out in the inning and Smith coming to the plate. He singled, his fourth hit of the night, and was removed for a pinch-runner after advancing to second. Three batters later, Jonathan Johnson, the pinch-runner, came around to score the winning run against the Yankees' affiliate.

Smith was the 11th overall pick in the 2013 First-Year Player Draft and began his first professional season slowly. He hit just .212 with a .508 OPS during April, but has since turned it around, even while playing in a home park that is notoriously tough for left-handed power hitters. He is hitting .325 with a .791 OPS in 52 games since the calendar flipped to May.

Overall this season, Smith is hitting .291 with a .707 OPS in 77 games. He has yet to hit a home run and has drawn 28 walks and struck out 49 times.
