On the same day that the Giants signed starter Brad Penny and the Rockies added starter Jose Contreras, the Dodgers one-upped their division rivals by acquiring starter Jon Garland from the Diamondbacks and slugger Jim Thome from the White Sox.

From MLB.com:

In return, the White Sox will receive Minor League infielder Justin Fuller. The D-backs will receive a player to be named, who, according to several Dodgers, will be Tony Abreu, but Abreu needs to first clear waivers. Abreu once was considered a top infield prospect, but his progress was stalled by three years of injuries.

The right-handed Garland, 29, moves into a rotation that has struggled to find a fifth starter all season and has been further weakened by the loss of Hiroki Kuroda, who was hit on the head by a line drive. Garland is expected to take the place of knuckleball specialist Charlie Haeger, with Vicente Padilla holding the spot for Kuroda, who could return to the rotation as soon as Sunday.

Thome, 12th on the all-time list with 564 career home runs, will give the Dodgers the left-handed threat that Matt Stairs provides the Phillies, who beat the Dodgers with a home run off the bench in the playoffs last year.

Coupled with their addition of Ronnie Belliard over the weekend, the Dodgers have set themselves up for a World Series run with these two moves. After the Rockies got within two games of the division lead in the NL West last week, L.A. clearly isn’t taking any chances as they head into the final month of the season. These moves fortify the back of the rotation, their bench, and their overall position depth.

After he went unclaimed at the 1:00 p.m. deadline on Monday, Brad Penny became a free agent and according to SI.com, has signed with the San Francisco Giants.

Initially, no one claimed Penny because a claiming team would have been responsible for the remainder of his contract. The Giants only have to pay him the pro-rated portion of the big-league minimum of $400,000, which will be less than $100,000.

Putting aside Penny’s numbers this season (7-8, 5.61 ERA), this is a quality signing by the Giants. He’s familiar with the NL West after pitching for the Dodgers for four and a half seasons and also offers an upgrade over Joe Martinez, who had been filling in for Randy Johnson after the Big Unit was placed on the DL with a shoulder injury in early July.

Pitching in the spacious AT&T Park should only help Penny’s performance, especially considering he had issues keeping the ball in the yard while playing in Boston this season. He should also be plenty motivated to join a contender, especially a contender whose rival is the team that Penny had a falling out with at the end of last season (the Dodgers).

Considering that Penny comes cheap, is still throwing in the mid 90s and will make an impact immediately, he’s a perfect fit for a Giants team that is coming off a sweep of the Rockies and is now tied for the NL Wild Card.

The Boston Herald is reporting that the Red Sox have released starter Brad Penny, who has been awful in his last four starts, compiling a 0-4 record and a 9.11 ERA. Penny will try to join a contender by the end of August in hopes of contributing this postseason.

One contender that would be a fit for Penny is the Giants. They’re a seriously flawed club offensively, so it would make sense that they would focus their attention solely on that weakness. But there aren’t any available bats, so their lineup is what it is. (Fans just threw up after reading that.)

They could, however, use an upgrade over fifth starter Joe Martinez, who is well liked and incredibly easy to root for, but has failed to get past the fifth inning in each of his last four starts. Granted, he’s 2-1 during that span, but he’s gotten an unusual (for the Giants) 8.0 runs per game over those four contests. The more telling sign of how Martinez has pitched is his ERA, which is 5.73.

Penny pitched for the Dodgers for four years (2005-2008) and therefore is familiar with the NL West. Outside of his bloated 6.28 ERA in 2008, he was anywhere from respectable to great while pitching in L.A., compiling a 3.90 ERA in 2005, a 4.33 ERA in 2006, and a 3.03 mark in 2007.

The Giants have six more games against the Rockies, who they currently trail in the Wild Card standings by three games. Since 2004, Penny is 14-4 against Colorado, so he’s obviously had a ton of success against a team the Giants are currently looking up at in the standings.

Granted, Penny might not start more than a game (if that) against the Rockies if he signs, especially considering that the two teams start a three game series this Friday in San Fran. But Penny stands to be an upgrade over Martinez, which is the most important factor for the Giants. Plus, if the club does sign Penny, Martinez could then help out a tired bullpen.

Fans would love to see San Fran call up top prospect Madison Bumgarner, but the Giants will likely leave him in the minors this season and then give him an opportunity to join the rotation next year when they’ll have to fill the spot that Randy Johnson once held.

So why not take a one-month shot on Penny?
