Infielders
Player Key stat Grade Skinny
Robert Andino 58 starts C+ Serviceable as backup and really stepped up after Izturis' appendectomy.
Aubrey Huff 13 homers C- Just never got going and eventually was traded for Single-A reliever.
Cesar Izturis 8 errors B- His defense stabilized a position that was a revolving door in 2008.
Melvin Mora 48 RBIs C- It's unfortunate that productive Orioles tenure ended with such a down year.
Brian Roberts 56 doubles A- Proved once again that he's one of the most dynamic leadoff men in game.
Ty Wigginton .400 slugging pct. C- Struggled defensively and wasn't power threat that team had hoped.
Outfielders
Adam Jones 19 homers B Breakout All-Star campaign curtailed by injury, bad second-half slump.
Nick Markakis 101 RBIs B- Final numbers solid, but they're down from '08 in too many categories.
Felix Pie . 266 avg. B Made more progress through course of season than any other Oriole.
Nolan Reimold 15 homers A- Rookie pretty much exceeded every expectation club officials had for him.
Luke Scott .208 avg. in 2nd half C Set career highs in homers and RBIs but tailed off badly.
Catchers
Matt Wieters .288 avg. B Had no chance of meeting bloated expectations, but got better and better.
Gregg Zaun 49 starts C+ He did nice job handling pitchers, mentoring Wieters before trade to Rays.
Starting pitchers
Brad Bergesen 13 quality starts A Rookie was team's best pitcher until come-backer ended his year.
Jason Berken 6-12 recordD Love his guts and competitiveness, though he knows it's a results business.
Adam Eaton 8.56 ERA F The numbers don't lie in this case: Stopgap starter was overmatched.
Jeremy Guthrie 35 HRs allowed C- Pitched 200 innings, but O's needed quality, not just quantity
David Hernandez 5.42 ERA C- Rookie's rocky finish put 2010 rotation spot in serious jeopardy.
Rich Hill 7.80 ERA Inc. Said he dealt with shoulder problems all year, so it's unfair to judge results.
Brian Matusz 5-2 record A- Started season at Single-A; ended it by dominating Yankees in Bronx.
Chris Tillman 5.40 ERA B- Have to take into account age, how dominant he was at Triple-A.
Koji Uehara 12 starts Inc. Effective when healthy, but that wasn't often enough for Orioles' liking.
Relief pitchers
Matt Albers 3 demotions D+ Consistency, conditioning questions dogged him all season.
Danys Baez 59 games C+ How quickly we forget that he nearly didn't make Opening Day roster.
Brian Bass 5.79 ERA in 2nd half C- Figured in some nice wins but staggered toward finish line.
Mark Hendrickson 4.37 ERA B+ Who expected him to emerge as one of O's most reliable pitchers?
Jim Johnson 6 blown saves C+ Shouldn't be judged only on rocky stint as closer, but that left bad taste.
Cla Meredith 3.77 ERA C It will be interesting to see how he fits into bullpen going forward.
Chris Ray 7.27 ERA F Perhaps it was too much, too soon for him after '07 Tommy John surgery.
George Sherrill 20 saves A- Bullpen completely imploded after he was traded to Dodgers in July.
