Five more guys from the Pre-Season Sleeper List.

Ryan Chaffee, RHP, Los Angeles Angels: Didn't get activated until the end of April, made six starts in May and got killed for Rancho Cucamonga (7.58 ERA, 19/17 K/BB in 30 innings, 37 hits). Shut down again, hasn't pitched in June, now on the roster of the rookie-level Orem Owls. Still gets grounders (1.80 GO/AO), but everything else went backwards on him. No word that I can find of an injury.

Edward Concepcion, RHP, San Francisco Giants: Hasn't pitched this year. Currently on AZL Giants roster.

Brandon Cooney, RHP, Baltimore Orioles: Great start at High-A Frederick, 0.55 ERA with 19/7 K/BB in 16 innings, six saves. Promoted to Double-A Bowie, has a 2.70 ERA with a 9/4 K/BB in 10 innings so far, just five hits allowed. 4.00 GO/AO so far this year. Looks good.

Drew Cumberland, SS, San Diego Padres: Brilliant season so far for Lake Elsinore: .371/.410/.546 with 20 steals. Walk rate is a bit low (15 in 240 at-bats), but his strikeout rate is reasonable with 30 whiffs, and he's putting his speed and gap power to good use. Looks great to me.

Justin De Fratus, RHP, Philadelphia Phillies: 2.30 ERA for High-A Clearwater, 11 saves, 37/11 K/BB in 31 innings, 22 hits allowed. Need to see at higher levels, but numbers are certainly strong so far this year.
