Key

Middle infielders

Mike Aviles, SS, Kansas City Royals

Aviles has already become a fixture in KC's lineup after his recent call-up. Yuniesky Betancourt and Chris Getz haven't done much to challenge him. Aviles' value will be heavily based on batting average, though, which has been fueled by high BABIPs in '08 and now; don't commit too hard.

Shallow mixed: Watch

Deep mixed: Acquire

AL-only: Acquire

Outfielders

Jack Cust, OF, Oakland Athletics

Aviles is begging for your attention

Reports speculate Eric Chavez's future with the A's is in question. If he were to leave Oakland in some fashion, the powerful Cust might find his way back to the bigs.

Pitchers

Brandon League, RP, Seattle Mariners

League recorded a five-out save for the M's Tuesday. Closer David Aardsma, shaky in his last two outings, hadn't pitched since Saturday but wasn't used. Ease off, conspiracy theorists; Aardsma's job probably isn't in jeopardy yet.

But if you're looking for a ratio helper, why not look for a groundball-friendly arm that's the likely next in line behind a closer with a small track record and scary peripherals? Though he hasn't this year, League showed K ability last year.
