NL West Notes: Bloomquist, Romero, Blake

The tightest division race in the National League is happening out west, where the Diamondbacks have taken a two-game lead over the Giants on the strength of five straight wins. ESPN.com's Buster Olney (Insider link) likens Arizona to a No. 14 seed in an NCAA tournament, holding a lead late in the game and gaining confidence that they can pull off an upset. Here are this morning's notes from around the NL West:

• The D'Backs didn't go out and acquire a replacement for Stephen Drew when he fractured his ankle, and Willie Bloomquist is making the decision look good, writes Olney. Since Drew's injury, Bloomquist is hitting .295/.349/.423 as the team's regular shortstop.
• J.C. Romero tells Troy Renck of the Denver Post that his friend LaTroy Hawkins had good things to say about the Rockies' organization, which pushed the lefty toward Colorado. Romero will throw a bullpen and take a physical today, and could be added to the Rockies' roster if both go well.
• Steve Dilbeck of the Los Angeles Times wonders what's next for the Dodgers' Casey Blake, who is "not the least interested in calling it a career" and "has no desire in going out on some injury-riddled, less-than-fulfilling season," according to Dilbeck.
• The Athletics have called up two former members of NL West clubs, both of whom were involved in trades earlier this season, writes John Shea of the San Francisco Chronicle. Brandon Allen, formerly of the Diamondbacks, and Bruce Billings, acquired from the Rockies in the Mark Ellis deal, will join the A's for today's game.
