Keys' Mummey has huge debut

Trent Mummey soaked up his opportunity to make a good first impression at Class A Advanced Frederick, posting a career night in the Keys' 14-7 rout of Winston-Salem on Monday.

Mummey finished 4-for-6 with a career-high five RBIs, falling a home run short of the cycle in his first game with the Orioles affiliate. He began the season at Class A Delmarva, raising his average to .291 in the South Atlantic League before the O's bumped him up to the Carolina League this weekend.

It was the most productive day of Mummey's career since falling a single shy of the cycle and plating four runs for Class A Short-Season Aberdeen on July 11, 2010.

The Auburn product, drafted by Baltimore in the fourth round of last year's Draft, doubled and scored in the first inning, lined an RBI single in the second and launched a bases-loaded triple and scored in the eighth. He capped his day with a two-out RBI single in the ninth.

Mummey, 22, strung together a seven-game hitting streak with the Shorebirds to raise his average as high as .294 on April 19. He was officially assigned to Frederick on Monday morning -- his last game with Delmarva was April 21 --- and was penciled into Monday's lineup in the No. 2 spot.

He split his first Minor League season last summer between Aberdeen and Delmarva, batting a combined .245 with three homers and 29 RBIs in 62 games.

The Jasper, Ala., native hit .366 with 17 homers and 54 RBIs in just 36 games with Auburn last year.
