The Frederick Keys' roster has undergone some changes, and the team's fortunes have started to change as well. After a poor April and May, Frederick has won eight of its last 15 games thanks to the contributions of some new players.

"Things are going better," Manager Tom Lawless said. "We've got some different arms who are starting to have good contributions."

Since June 2, the Keys' roster has been overhauled. Infielder Levi Robinson and right-hander Joe Coppinger were demoted to Delmarva of the lower-level Class A South Atlantic League. Outfielder Branden Florence was called up to Frederick from extended spring training, and right-handed pitchers Chris Ray and Hayden Penn joined the squad from Delmarva.

Ray has had two solid starts and Penn allowed a run in five innings in earning a win in his first start for the Keys (16-43).

Florence has hit .345 with a home run and seven runs batted in eight games. The Keys are hitting .270 with 48 home runs, both good for third in the Class A Carolina League.

"There were guys who were pitching well in Delmarva and deserved a chance," Lawless said.

"Some of the guys here didn't play very well [and were demoted]. . . . That's just the nature of the game."

Meantime, left-handed starters Richard Stahl and Ryan Hannaman were placed on the disabled list.

Stahl, who strained his groin, is the team's leader in wins, and he has the lowest earned run average of any Keys starter or reliever with more than three appearances.
