Norfolk Tides (AAA)
The game between the Triple-A Norfolk Tides and Buffalo Bisons didn't happen due to the inclement weather. Since it was the last matchup of the season between the two teams, it won't be rescheduled. The Tides will begin a four-game series against the Toledo Mud Hens on Saturday night at Harbor Park.
Recap: The scoreless drought continues for the Baysox, but there was some good news at Prince George's Stadium on Friday night.
Although Bowie's streak without a run reached 27 innings in a 3-0 loss to the SeaWolves, first baseman Brandon Snyder returned to the lineup after missing six games with a minor back injury.
"I hadn't seen a pitch in six days, and obviously that's tough," Snyder said. "The first at-bat, I actually saw the ball pretty good."
The 22-year-old first baseman was 1-for-4 with a double, and he is now batting .340 with nine home runs and 38 RBIs in 46 games this season for the Baysox.
"It just takes one or two guys to get hot, and everyone kind of feeds off of it," Snyder said when asked how the team could fix the recent offensive struggles.
Bowie starting pitcher Sean Gleason (3-4) allowed three runs (two earned) and five hits in five innings. The 24-year-old right-hander walked four batters and collected one strikeout.
Second baseman Miguel Abreu led the Baysox with two hits, but the team struck out 10 times in the game. Bowie designated hitter Dave Krynzel had three strikeouts, and catcher Guillermo Rodriguez fanned twice.
"Fundamentally, the guys seem like they're trying too hard," Baysox bench coach Moe Hill said. "When you put pressure on yourself, it starts to mount up ... that's why they call them slumps."

Frederick only collected three hits in the game. Shortstop Pedro Florimon Jr. was 1-for-3 with a run scored for the Keys, and first baseman Robbie Widlansky picked up an RBI.

The game was delayed for 2 hours and 59 minutes before the first pitch because of rain.

Keys starting pitcher Brian Matusz tossed six scoreless innings, but he didn't factor in the decision. The 22-year-old left-hander struck out five batters and scattered five hits.
Relief pitcher Cliff Flagello (1-1) gave up five runs (two earned) and five hits in two innings for Frederick.
