OWINGS MILLS - A blown coverage in the Ravens' secondary left Steelers wide receiver Emmanuel Sanders streaking wide-open over the middle of the field.
Quarterback Charlie Batch hit Sanders in stride 20 yards down the field on a play that could've gone for much more, and possibly even a touchdown, if not for Sanders fumbling as he attempted to secure the football.
The play was one of a number of breakdowns in Baltimore's secondary that led to big-yardage plays for Pittsburgh's passing game on Sunday.
Batch completed six passes that went for gains of 15 yards or longer, five of which came during the second half.
"It was more just keeping our eyes on our guy as opposed to jumping a screen-fake or another kind of fake to another guy," Ravens coach John Harbaugh said. "We got a little overanxious. I would say it was over-aggressiveness more than it was miscommunication in those instances."
The veteran Batch, the Steelers' third-string quarterback, was making just his ninth start since 2002, forced into action because of injuries to both starter Ben Roethlisberger and backup Byron Leftwich.
Batch was 20-of-34 for 199 yards with no touchdowns and three interceptions amid Pittsburgh's 20-14 loss to the Browns a week earlier. Against Baltimore, however, he threw for 276 yards and a touchdown and led two fourth quarter scoring drives as the Steelers erased a late deficit to come away with a 23-20 victory.
Batch threw for just 57 yards in the first half, but was 16-of-20 for 219 with the touchdown in the second half.
The Ravens led 20-13 midway through the fourth quarter before Batch connected with tight end Heath Miller for a 7-yard touchdown, a score that was set up by a 17-yard completion from Batch to Sanders just two plays earlier.
He later guided a 12-play, 61-yard drive that ended with Shaun Suisham's game-winning 42-yard field goal as time expired.
Batch's 276 yards represented his largest yardage output since 2002.
"He's a professional quarterback," Baltimore safety Bernard Pollard said of Batch. "He's on the roster for a reason. He can make throws. I look at it as we let some things get away. We should have stepped on their throat and choked them when we had a chance, and we didn't do it."
It didn't help that the Ravens' pass rush struggled to generate consistent pressure on Batch, providing the quarterback with ample time to sit in the pocket and look for big plays down the field.
"They just did a great job of blocking us up front," Baltimore defensive tackle Haloti Ngata said. "Sometimes they had max protection, and sometimes they didn't. We just didn't do a great job of converting. I think we were playing a little bit more [to defend] the run game, and they did a great job of mixing it up."
Regardless, the Ravens' pass defense remains a primary concern heading into the latter part of the regular season, a four-game stretch that includes matchups with Robert Griffin III, Peyton Manning, Eli Manning and Andy Dalton.
Baltimore is ranked 22nd out of the NFL's 32 teams against the pass, yielding an average of nearly 250 yards per game through the air.
"We just have to regroup," Ravens safety Ed Reed said. "We know this is a journey. ... This is far from over. That's why it's called a season."
