U-Md. Product 'Could Be Special'
While the focus of Class A Hagerstown is on last year's first-round pick Chris Marrero (.311, 10 homers, 40 RBI in 39 games), CF Justin Maxwell (Sherwood) is impressing as well. As a leadoff man, Maxwell has 11 homers already, driving in 27 runs with a team-high .950 on-base-plus-slugging percentage. "He could be special," General Manager Jim Bowden said. The 6-foot-5, 225-pound University of Maryland product, 23, could be a candidate to move to high-Class A Potomac later in the summer. . . .
RHP Garrett Mock, acquired last year with Matt Chico in the trade that sent Livan Hernandez to Arizona, missed the first month-and-a-half of the season with a knee problem, but was impressive in a six-inning, three-hit, no-run outing for Potomac on May 15. Mock, though, went back to the disabled list. Club officials say he is building his shoulder strength, and is likely to miss only one start. . . .
RHP John Lannan, promoted from Potomac to AA Harrisburg, made his first start for the Senators on Monday, allowing five hits and three runs over seven innings in what became a 5-4 loss to Erie. Bowden said that most other promotions in the minors will occur around midseason. . . .
OF Kory Casto is 2 for 23 (.087) since being sent from the Nationals to Class AAA Columbus on May 15. Columbus OF Brandon Watson, the Nationals' Opening Day center fielder last year, has a 20-game hitting streak and is hitting .321.
