Mariano's arm still not right

When you cut through all the positives Mariano Rivera spit out yesterday about his right forearm, the most important words he uttered after playing catch left a small amount of concern. "It's a little bit tight," Rivera said after tossing 40 throws from about 90 feet to pitching coach Ron Guidry during batting practice prior to last night's game against the Orioles at Camden Yards. "It's better today. There is less tightness. That's the good news. The more I threw it got looser. It felt much better."
