Derek Norris has seen his status as one of the Nationals' top hitting prospects overshadowed this season by a certain No. 1 Draft pick. He had the spotlight on Friday, at least briefly, in Erie.

Norris homered twice, including a go-ahead blast in the eighth inning, before the Senators fell to the SeaWolves, 6-5, on a walk-off homer in the 10th at Jerry Uht Park.

The 22-year-old, considered the Nationals' best catching prospect, has been a man on a mission the last week or so, with five longballs and 12 RBIs in his last 10 games. He and Tyler Moore slammed back-to-back shots in the eighth -- Moore's drive was a game-tying two-run shot -- before Michael Bertram upstaged both with a leadoff homer in the 10th.

It was the second time this season the Senators have gone back-to-back and the sixth time they've had a player hit two homers in a game.

Norris batted .125 in April and effectively fell off the radar, especially in the midst of Bryce Harper's power display at Class A Hagerstown, the team where Norris himself enjoyed his best season to date with 23 homers in 2009. He's bounced back since, hitting .277 in May, a month he wound down with homers in three straight games. He slugged another on May 28 and had knocked in two runs since then.

The Kansas native keyed the Senators' comeback with his first homer of the night, a two-run shot in the seventh that reduced the deficit to 4-2. Moore followed with his 10th dinger in the eighth before Norris took reliever Zach Simons to left for his eighth of the season.

Norris, a 2007 fourth-round pick, was named MiLB.com's Class A Best Hitter of the Year in 2009 after batting .286 with 23 homers, 30 doubles and 84 RBIs at Hagerstown. He hit a dozen homers and knocked in 49 runs last year at Class A Advanced Potomac.

Bertram, who also homered Thursday, led off the 10th with his third of the season and second allowed by Carlos Martinez (0-2) in his last three outings.
