Oakland added depth nearly everywhere on the diamond, a reaction to three consecutive seasons marred by injuries, but the team did not add any power besides re-signing last year's top home run hitter, Jack Cust. The team's strengths appear to be pitching, speed and depth. ARRIVALS: RHP Ben Sheets (free agent from Brewers), OF Coco Crisp (signed as a free agent from Royals), 3B Kevin Kouzmanoff (trade with Padres), INF Adam Rosales (trade with Reds), INF Steve Tolleson (waivers from Twins), OF Gabe Gross (free agent from Rays), INF Jake Fox (trade with Cubs), RHP Jason Jennings (free agent from Rangers). DEPARTURES: OF Scott Hairston (traded to Padres), INF Adam Kennedy (free agent, signed with Nationals), INF Nomar Garciaparra (retired), RHP Brett Tomko (free agent, unsigned), LHP Dana Eveland (traded to Blue Jays), RHP Santiago Casilla (released, signed minor league deal with Giants). SPRING FOCUS: Oakland needs to find a fifth starter from a group that includes one of last year's mainstays, RHP Trevor Cahill, who is the leading candidate. In addition, the club must evaluate INF Eric Chavez's health, which could determine several roster spots. If Chavez can handle utility infield duties after back surgery, INF Adam Rosales and possibly INF Jake Fox will open the season in the minors. PROJECTED ROTATION: 1. RHP Ben Sheets 2. RHP Justin Duchscherer 3. LHP Dallas Braden 4. LHP Brett Anderson 5. RHP Trevor Cahill Sheets signed a one-year, $10 million deal with Oakland and already has been named the opening-day starter, while two-time All-Star Duchscherer re-signed with the A's after missing all of last year because of a minor elbow injury and clinical depression. Anderson's fine rookie season could earn him the No. 3 spot over the more experienced Braden, but Braden was the team's opening-night starter last year, while Cahill is the most likely candidate for the final spot ahead of LHP Gio Gonzalez and RHP Vin Mazzaro. PROJECTED BULLPEN: RHP Andrew Bailey (closer) RHP Michael Wuertz RHP Joey Devine LHP Craig Breslow RHP Brad Ziegler LHP Brad Kilby LHP Gio Gonzalez There's no doubt that this is one of the league's best units: Bailey is coming off a Rookie of the Year season, while Wuertz's season was among the best of all major-league relievers. Devine was last year's projected closer but missed the season after Tommy John surgery, and Ziegler also has served as Oakland's closer. Breslow will be the primary lefty, and while Jerry Blevins might get a shot with a good spring, Kilby's excellent September showing probably gave him an edge going into camp. Gonzalez is a possible long man if he doesn't crack the rotation. PROJECTED LINEUP: 1. LF Rajai Davis 2. CF Coco Crisp 3. C Kurt Suzuki 4. DH Jack Cust 5. 3B Kevin Kouzamanoff 6. RF Ryan Sweeney 7. 2B Mark Ellis 8. 1B Daric Barton 9. SS Cliff Pennington The biggest question marks here are at first base -- which could be some combination of Barton, Eric Chavez, Chris Carter and Jake Fox as the season goes along -- and shortstop, where Pennington is relatively unproven though he was a pleasant surprise in the second half of 2009. The lineup has little power apart from Jack Cust but lots of speed, with Davis, Crisp, Sweeney, Ellis, Pennington and even Suzuki capable of stealing bases. Expect the A's to do a lot of running. PROJECTED RESERVES: C Landon Powell INF Eric Chavez INF Jake Fox OF Gabe Gross If Chavez's twice-repaired back won't allow him to play in the field, he will have to make a decision about his future (he has suggested he will retire) and the A's will need a backup middle infielder. That's likely Adam Rosales, who was acquired from the Reds. Chavez believes he can handle backing up everywhere, including shortstop, if his back is OK. Gross' competition for the backup outfield spot includes Travis Buck, who was a starter in right two years ago, and top prospect Michael Taylor, who could be up by the middle of the season. TOP ROOKIES: OF Michael Taylor, picked up in the Roy Halladay/Cliff Lee deal from the Phillies in exchange for sending 3B Brett Wallace to Toronto, is a good bet to be up this season. The former Stanford player, 24, hit .320 with 20 homers and 84 RBI at two levels last year. 1B/OF Chris Carter, 23, also is expected to be on the roster at some point. The A's minor league player of the year hit .329 with 28 homers and 115 RBI at two levels in 2009. MEDICAL WATCH: --CF Coco Crisp (strained left hamstring) was hurt March, and he was expected to miss at least a few days of action. He expects to be ready for opening day. --3B Eric Chavez (back surgery in June 2009) was ready for spring training, although the A's were likely to take it easy with him. --RHP Joey Devine (Tommy John elbow surgery in April 2009) was shut down for a week in mid-March. He might not be ready for the start of the season. --RHP Ben Sheets (right elbow surgery in February 2009) is expected to be Oakland's opening-night starter. --RHP Justin Duchscherer (elbow surgery in March 2009, clinical depression) was slowed by lower back pain early in camp.
