CLEVELAND -- Mariano Rivera's shoulder is still sore, and the New York Yankees closer received a cortisone shot on Thursday.

According to the Yankees, his status remains day to day. He has not been put on the disabled list.

After playing catch in the Yankees' bullpen before Wednesday's game, Rivera said he still had tightness in his shoulder.

"I was really disappointed,'' Rivera said following the Yankees' 14-7 win over the Indians. "I was expecting something more and it didn't happen.''

Rivera received more testing in Tampa, Fla. -- the Yankees are off -- on Thursday at the team's training complex. He then received the cortizone shot.

Rivera said if he doesn't get the shot, he'll go on the disabled list.

"Either one,'' said Rivera, who had never had a cortisone injection in his arm or shoulder. "I just want to get better and do the best thing for the team and myself. If I do go (on the DL), it will be the best for me.''

Yankees manager Joe Torre said the Yankees won't hesitate putting the right-hander on the DL if needed.

New York opens a three-game series in Tampa on Friday.

"We'll do whatever is best for him,'' Torre said. "It's in an area where a shot may help.''

Rivera's shoulder tightened up after he made just six pitches on Saturday against the Boston Red Sox. An MRI exam taken Monday revealed the strain, but no other damage.

The All-Star is 1-4 with a 3.06 ERA and 24 saves in 28 chances this season.

With Rivera out, Torre is using Steve Karsay and Mike Stanton in closing situations.

Rivera wanted to test his shoulder by playing catch on Wednesday.

After doing his running in the outfield, Rivera chatted with pitching coach Mel Stottlemyre before disappearing into the Yankees' bullpen in right field.

He emerged moments later, and spent the final 15 minutes of batting practice signing autographs for fans down the right-field line before running off the field with Stottlemyre.

Rivera went straight to Torre's office and was in there for 10 minutes when reporters were asked to leave the clubhouse.

"I was positive that I would be feeling better today, and I wasn't feeeling better at all,'' he said. "It's not painful, but I can't get rid of it (soreness).''

Rivera was on the disabled list from June 10-25 with a strained right groin. It was only his second trip to the DL, with the other coming in 1998 when he also had a groin strain.

The only time he has gotten a cortisone shot it was for an ankle injury.
