Yankees acquire SS Brendan Ryan

BALTIMORE -- In a move that could mean they are no longer counting on Derek Jeter to return for the final 17 games of the season, the New York Yankees have acquired infielder Brendan Ryan from the Seattle Mariners for a player to be named later.

Ryan, a superior fielder with a weak bat, hit just .192 in 87 games for the Mariners this season, with three home runs and 21 RBIs. A 31-year-old veteran of seven major league seasons, Ryan is a career .238 hitter and has 18 lifetime home runs.

But Ryan's true value is with his glove; his play at shortstop was recently featured in a Grantland.com story to demonstrate flaws in the 39-year-old Jeter's defense.

Ryan has also played second base, third base, left field and right field, but has played the vast majority of his games at shortstop. It is expected he would replace Eduardo Nunez, a shaky fielder who has been the Yankees regular shortstop in Jeter's absence. Nunez's throwing error led to four fourth-inning runs in Tuesday night's 7-5 win over the Orioles.

Jeter has appeared in just 17 games this season, batting .190 with one home run and seven RBIs. He has made two trips to the disabled list after missing the first 91 games of the season with injuries related to the broken left ankle he suffered in Game 1 of the ALCS last October.

Jeter was removed from a game on Saturday with soreness in the ankle, which was surgically repaired in October but re-fractured during spring training. Officially, the Yankees say Jeter is day-to-day, but it is unknown when, or if, he will return to the Yankees' lineup.

"He's still in a holding pattern," manager Joe Girardi said Tuesday afternoon. "He's not going to be out on the field today. I don't know if that means he's available to me in an emergency, but he's not going to do anything today."

Jeter underwent a CT scan on his ankle Saturday and although Yankees team physician Chris Ahmad said the results were negative, the club sent the test to Dr. Robert Anderson, who performed the surgery, for a second evaluation.

"We hope at some point it will be forgotten but right now it's something that he's still dealing with," general manager Brian Cashman said. "If he felt well enough to play and he was pain-free, he'd be back out there."

Jeter is with the team on this road trip but has not spoken to reporters since leaving Saturday's game. He slipped out of the clubhouse after Tuesday night's game, accompanied by pitcher CC Sabathia, without addressing the media.
