Pregame A’s notes: Foiled attempt to penetrate Green Monster; finding playing time for Adam Rosales

A few of us media types wandered down the left-field line here at Fenway during BP and tried to sneak into the door that takes you inside the Green Monster (you remember … the door Manny Ramirez entered to take his infamous in-game potty break a few years ago). Anyway, long story short, we were denied. They said nobody was allowed in there during batting practice. But you can’t fault the effort. …

Adam Rosales draws a start tonight at third base in place of Kevin Kouzmanoff. Are you surprised Rosales hasn’t gotten more starts after he played so well at the beginning of the road trip? He’s been a spark when he’s played, but with Mark Ellis healthy and Gabe Gross getting regular time in left field, it’s tough to find a spot for Rosales. If Cliff Pennington continues to slump, I think Rosales needs to start seeing more time at shortstop. Pennington enters tonight’s game in an 0-for-27 funk. That’s the longest hitless streak by an Athletic since Jack Hannahan went 0-for-28 during one stretch in August 2008.

–Bob Geren said everyone should be available in the bullpen tonight, but he’d like to avoid using Michael Wuertz, who’s thrown in the last two games. Wuertz admitted he struggled last night as he was on the back end of pitching back-to-back games. His ability to perform on consecutive days is key for Oakland’s bullpen. He probably won’t duplicate his 2009 dominance, but the A’s need him to come close.

–News bit: The A’s released minor league infielder Yung-Chi Chen, who spent time in A’s big league spring training in 2009.

Tonight’s lineups:
A’s: Davis CF, Barton 1B, Sweeney RF, Suzuki C, Cust DH, Ellis 2B, Gross LF, Rosales 3B, Pennington SS; Sheets RHP.

Red Sox: Scutaro SS, Pedroia 2B, Ortiz DH, Youkilis 1B, Drew RF, Beltre 3B, Hermida LF, Varitek C, McDonald CF; Matsuzaka RHP.
