FORT MYERS, Fla. - Boston Red Sox shortstop Nomar Garciaparra will probably not be ready for Opening Day because of inflammation in his right Achilles' tendon.
"I think it's more unlikely as time goes on," team doctor Bill Morgan said Saturday. "We wouldn't rule it out, though."
Garciaparra was injured three weeks ago when he was hit in the right heel by a ball during batting practice. He has not played since March 17, going hitless in eight at-bats over four games this spring.
Garciaparra took about 20 swings in the batting cage before Saturday's game against Baltimore, then took about 20 grounders at short. He said he was not thinking far enough ahead to consider whether he will miss the opener.
Tests on Garciaparra's leg have shown no major damage. Morgan and Garciaparra both said there is no similarity to the wrist injury that required surgery on Opening Day in 2001 and hampered him for the next two seasons.
In other injury news, Morgan said right fielder Trot Nixon will go to a rehabilitation center in Miami to recover from a herniated disk. Nixon will stay there for two weeks and; in the second week he can begin baseball activity such as light throwing and swinging a bat.
RANGERS: Texas reliever Jeff Zimmerman will have exploratory surgery to determine the extent of the latest damage to his right elbow.
The 31-year-old right-hander met with Dr. Lewis Yocum and will have the operation next week.
Zimmerman has had two reconstructive surgeries on the elbow and has not pitched in a major league game since Oct. 7, 2001.
He reinjured the elbow in a "B" game on March 14 against Seattle.
l Texas acquired minor league outfielder Daryl Clark from the Milwaukee Brewers for a player to be named.
Clark, 24, split time last season between Class-A High Desert and Double-A Huntsville.
Also Friday, the Rangers sent right-hander Chris Mabeus back to the Oakland Athletics.
TIGERS: In Detroit, right-hander Franklyn German was optioned to Triple-A Toledo and reassigned catcher Guillermo Rodriguez and infielder Warren Morris to minor league camp.
German, 24, made 45 relief appearances for Detroit last year and tied for the team lead with five saves. He went 2-4 with a 6.04 ERA and 45 walks in 44w innings.
Morris hit .272 with six homers and 37 RBI last season.
