Last night was a recurring bad dream. Baltimore starting pitcher Daniel Cabrera threw his usual 100-plus pitches, but it took him less than five innings to do it as his maddening, two-out problems led to a 7-4 defeat to the Washington Nationals, generally considered a not-ready-for-prime-time team and the NL East's last-place club. Abetting Cabrera's shaky outing (four walks, seven runs in 4 2/3 innings) was a lethargic offense. Baltimore's Melvin Mora hit a three-run homer in the second inning but that was it, other than a solo shot by Miguel Tejada in the ninth. The Orioles are now six games under .500, in last place in the AL East behind Tampa Bay (is that sobering or what?) and have lost eight of their last 10. In a cruel twist, the O's bullpen -- a collective goat so far this season -- pitched a little more than four innings of two-hit, no-run ball.
