International League:

Chris Snyder slugged a two-run homer and winner Zach Britton pitched seven innings of five-hit ball Wednesday as Norfolk won 4-1 to start a series at Charlotte.

Zelous Wheeler drove in two runs for the Tides (74-64), who preserved their half-game lead over Rochester in the IL wild-card race with their fourth straight victory.

Earlier in the day, the parent Baltimore Orioles recalled pitcher Kevin Gausman from Norfolk.

They made room by optioning lefty Wei-Yin Chen, a regular member of their rotation, to the Gulf Coast League in a procedural move. He'll be back up for his next Baltimore start.

Left-hander Daniel Schlereth, whose father, Mark, is an ESPN football analyst and former Redskins offensive lineman, was reinstated from the disabled list to take Gausman’s spot.

The Tides have six games remaining in the regular season.

Eastern League:

The Richmond Flying Squirrels (69-68) kept their fading playoff hopes alive by winning 1-0 at Reading, which had won the first two games of the series in Pennsylvania.

Kelby Tomlinson drew a game-opening walk, went to third on Skyler Stromsmoe's double and scored on Adam Duvall’s groundout. The run stood up as four Flying Squirrels combined to pitch a four-hitter against the Fightin Phils (59-78).

In both previous games of the series, the Squirrels took leads into the ninth inning but eventually lost in walk-off fashion. With about a week left in the season, Richmond began the night 4 1/2 games out of second place in the Western Division, which carries a playoff spot.
