The Washington Nationals hadn't suffered a significant injury for eight days, an eternity for them. Saturday, though, the streak ended: right-hander T.J. Tucker was placed on the 15-day disabled list with inflammation in his right elbow, and the team recalled right-hander Travis Hughes from Class AAA New Orleans.

Tucker, who spent five weeks on the disabled list with a groin strain, said his elbow has bothered him since he was activated on May 26. He had allowed seven runs in his last 41/3 innings, pushing his ERA to 6.39.

"I just don't feel the same," he said.

Hughes, who was claimed off waivers from the Texas Rangers on April 7, went 2-4 with a 2.57 ERA and six saves in 32 appearances at New Orleans. The 6-foot-5, 27-year-old was chosen over lefties Joe Horgan (3-1, 4.18 ERA) and C.J. Nitkowski (1-0, 0.00 ERA), who have both spent time with the Nationals.

"I want someone who can get hitters out," Manager Frank Robinson said.

Loaiza Will Not Start

Right-hander Esteban Loaiza, scheduled to start Sunday's series finale, is battling soreness in his neck, and he will be skipped in the rotation. Sun Woo Kim, who is 1-0 with a 3.18 ERA, will make his second start of the year. If the injury, which Loaiza said he woke up with last week, gets better, Loaiza could pitch Friday at home against Toronto. . . .

Second baseman Jose Vidro, on the disabled list with a badly sprained left ankle and tendon damage, joined the Nationals. He played catch and ran prior to the game, and hit in the batting cage for the first time since he suffered the injury on May 4 in Los Angeles. He hopes to return next week. . . .

Third baseman Vinny Castilla, who entered Saturday's game 10 for his last 53 -- dropping his average from .287 to .265 -- dropped to seventh in the lineup. Robinson believes Castilla is trying to pull the ball too much and has lost patience.

"He's swinging at so many first pitches, it's unbelievable," Robinson said. "And they're not good pitches."
