CHARLESTON, W.Va. -- The West Virginia Power was in need of some ninth-inning magic Wednesday night and Chris Diaz provided the abracadabra.
The 22-year-old shortstop sent a two-run double down the left-field line with one out to cap a four-run rally in the final frame and send the Power past the Delmarva Shorebirds 4-3 to sweep the three-game series. A paid crowd of 1,229 attended the South Atlantic League matchup.
West Virginia (24-14) remained 11/2 games ahead of the Hagerstown (Md.) Suns in the Northern Division.
Diaz, an 11th-round pick of the Pittsburgh Pirates in last year's June draft, was 0 for 3 in his first three plate appearances Wednesday. The Miami resident worked a 2-0 count with the bases loaded then ripped the next pitch just inside the left-field line for the walk-off hit.
The Power players ran out to second base and mobbed Diaz and the celebration carried on to shallow center field before it broke up. The Power's 7-8-9 hitters were hitless in nine at-bats going into the final frame.
"I was looking for one pitch and one pitch only, a fastball in, and I got it and it just took a hack at it,'' said Diaz, who had his second winning hit in professional ball.
"We just had some good at-bats [in the ninth inning]. It was just an amazing feeling. We didn't have a good game to begin with and just to end it that way ... this team never gives up. This team is just resilient.''
The Power appeared dead in the water, mustering just four hits and no runs through the first eight innings. West Virginia equaled that hit total in the bottom of the ninth as it sent seven batters to the plate.
Josh Bell got the Power's mojo going, getting hit with a pitch leading off the ninth. Jordan Steranka followed with a double on a line drive to left field to put runners at second and third with none out.
