Orioles manager Buck Showalter said Friday night that he didn't expect center fielder Adam Jones' left hamstring strain to require a stint on the disabled list, and Jones said he hoped it was a short-term problem, but the urgency to get him back into the lineup will be compounded by the lack of a real replacement waiting in the wings.Showalter said the club would consider all contingency plans over the quick turnaround between Friday's 14-4 loss to the New York Yankees and Saturday's matinee at Yankee Stadium."You always try to attack the what-ifs, and we'll see what our best options are and go forward," Showalter said. "I'll continue to look from within. [Executive vice president Dan Duquette] is here. We'll talk some and see what we've got. There are some roster issues here that are complicated."Most complicated is the fact that their options are severely limited. Top backup Joey Rickard hasn't played in over a month with a torn ligament in his thumb, and is still several weeks from his return. Nolan Reimold, who took over for Jones on Friday, has been struggling terribly at the plate and looked uncomfortable fielding at the position.Cuban outfielder Dariel Alvarez is the only other option on the 40-man roster, and he has not inspired confidence during his brief stints in the major leagues.Alvarez is batting .250 in 14 major league games, and he's hitting for average this year at Triple-A Norfolk, not power. He's batting .293 with four home runs in the minors, after 15 and 16 homers in his first two full seasons stateside, respectively.He shares time in the Tides outfield with several players who have experience in center field, though none are on the 40-man roster. Mike Yastrzemski has played 38 games in center field for Norfolk and brings versatility and a touch of speed, though he's batting .223 in Triple-A this year and .195 since the All-Star break.Those with major league experience in the Norfolk outfield are Xavier Avery and L.J. Hoes. Hoes seems to be the primary center fielder for the Tides, making 65 starts for them, and is batting .232 with a .625 OPS and six home runs. He last appeared in the majors last season with the Houston Astros.Sitting below them, however, are a pair of major league veterans biding their time at Double-A Bowie. Julio Borbon already has been up as the Orioles' emergency center fielder and speed-and-defense option in the outfield, but returned to Bowie for regular playing time afterward to avoid the logjam in Norfolk's outfield.The Orioles also last week signed veteran Chris Dickerson, who hadn't played in a year after shoulder surgery, to a minor league contract in preparation for a situation like this.The 34-year-old Dickerson is batting .316 with a pair of home runs in five games for the Baysox, and has played two of his five games in center field.None can come near to approximating what Jones does for the Orioles, both in terms of keeping a limited defensive outfield functional and topping the batting order the way he does. To add any of them, save Alvarez, the Orioles would need to make a 40-man-roster move as well.Add that cocktail of circumstances together, and the Orioles had better hope Jones' hope after Friday's game comes true."Tomorrow, [I] might feel great," he said. "I'm always optimistic."jmeoli@baltsun.comtwitter.com/JonMeoli
