The bell tolled another trade deadline come and gone on Tuesday afternoon. In the wake of talk about the effect of new wild card rules on the trade market, and some grand speculation in both directions, some big names, and some big players too, will be wearing new jerseys for the rest of the season. Unfortunately for the New York Yankees, the two aren’t mutually exclusive. Just a few years ago, their trade for Ichiro Suzuki would’ve deserved its own full post. But it’s 2012, and instead, it’ll only get these couple sentences. Here are the five trades likely to have the biggest impact on the season moving forward:

5. Omar Infante and Anibal Sanchez to the Detroit Tigers

For the Detroit Tigers, it’s now or never. The team has made it no secret that they are done saying “next year,” and little has made that strategy so abundantly clear as trading the team’s top pitching prospect in Jacob Turner to the Marlins for Infante and Sanchez. Currently three games behind the Chicago White Sox in a tight race for the AL Central crown, their two newest faces fill two big holes: second base and the middle of its rotation. We’ll have to wait and see how Sanchez performs and Turner Develops to know which team got the better deal long term. But Infante and Sanchez will do more for the team right now, and that’s all there is for the Tigers.

4. Hunter Pence to the San Francisco Giants

The Giants are just one game up over the Dodgers in the NL West, and given all the moves LA has been making (discussed below), San Fran had to come up with some sort of counter. What they came up with is two-time all-star Hunter Pence, who’s hitting .271 with 17 homers and 59 RBI this year. In return, the team shipped Tommy Joseph, Nate Schierholtz, and Seth Rosin to Philadelphia. Joseph, a catcher who was one of the team’s best two or three prospects depending on who you asked, is the centerpiece of the deal. The Giants were willing to let him go for Pence, perhaps because they’ve already got Buster Posey behind the plate. After giving up one of their top pitching prospects to rent Carlos Beltran last year, it’s notable that the Giants secured Pence, who’s under contract through 2013. He’s not going to hit as many home runs as he did in Citizens Bank Park, but Pence will be a very important part of the lineup for more than just a few months.

3. Ryan Dempster to the Texas Rangers

The Angels and Dodgers were the deadline’s biggest movers and shakers, so like the Giants, the Rangers had to come up with something to better their squad for the playoff race to come. Dempster may be 35 years old, and while his 2.25 ERA and 1.04 WHIP are certainly well above the general expectation, the numbers aren’t a total anomaly. Recall that in 2008 he went 17-6 with a 2.96 ERA and 1.21 WHIP over more than 200 innings. Although 15 years in the bigs, it’s Dempster’s first time in the American League, and his 4.63 ERA in 50 career interleague games aren’t exactly a bright spot, they needed someone to fill the hole injuries have made in their rotation. He’s no Zach Greinke, but Dempster will be a big factor if the team hopes to reach the World Series for the third straight season.

2. Hanley Ramirez to the Los Angeles Dodgers

If this was a list of the trades likely to have the biggest impact over the next few years, as opposed to just this season, this one might’ve been at the top of the list. Ramirez might be having a down year (or two) by his standards, hitting .246 with 15 home runs and 56 RBI. And sure, it’s been a little while since 2009, when he hit .342 and brought home a battle title, or his 30/30 campaign in 2008. But Ramirez is coming off an injury and more importantly, he’s still only 28 years old, smack dab in the middle of his statistical prime. Considering the Dodgers gave up very little to get him and also scored Shane Victorino, they might just be the season’s biggest trade deadline winner.

1. Zach Greinke to the Los Angeles Angels

As I said, long term, Greinke moving to the Angels might not be that huge. Who knows where he’ll end up when he becomes a free agent this off season. But with the spot the Angels are in right now, his move to LA is the deadline’s biggest. It’s no surprise that like the Giants and Dodgers, both the Angels and Rangers are on this list. Arguably two of the three best teams in the American League reside in the Western division, and as I discussed last week, playoff spots are no longer created equal. Yes, the Dodgers are in a similar position, and yes, the Rangers made a similar move, but the Angels now have Greinke, who was indubitably the best starting pitcher on the market, to shore up a rotation that already includes Jered Weaver, C.J. Wilson, Dan Haren, and Ervin Santana. Pitching is the name of the game when it comes to the playoffs to begin with. But what’s crucial for the Halos is that even if they do find themselves forced to employ Weaver in a wild card play-in, they’re not so screwed as most other teams might be with a gang like that to follow him.

Giants’ first baseman Brandon Belt is the 26th ranked player on MLB.com writer Jonathan Mayo’s Top 50 Prospects List for 2011.

If there are 25 prospects having a better spring than Belt, then I need my eyes checked.

Belt went 3-for-4 with an RBI double and a solo home run in a win over the White Sox on Wednesday. It was his second dinger of the spring and he’s now hitting .302 with 10 RBI over 43 at bats. The kid is absolutely tearing the cover off the ball and making the Giants’ decision about whether or not he should break camp with the big league club.

But there are a couple of problems.

Problem I: Aaron Rowand
Rowand still has two years left on his ridiculous contract and if Belt makes the Opening Day roster, he’ll force Aubrey Huff to move into an already crowded outfield. The Giants would likely either have to eat Rowand’s contract and/or bend over and take less value in a trade, neither of which they seem ready to do.

Problem II & III: Nate Schierholtz and Travis Ishikawa
Both are out of minor league options and one can make a case that both deserve a roster spot. Schierholtz has a cannon attached to his right arm and is a left-handed bat, while Ishikawa plays an outstanding first base and proved to be a nice bat off the bench last year. Teams would probably be more interested in trading for Schierholtz than either Rowand or Ishikawa, but if the Giants were to keep Belt then they would need to part with at least one other player. (Thus, Belt, Schierholtz, Rowand and Ishikawa are all fighting for two roster spots.)

Jose Guillen can’t play defense, can’t get on base and he can’t hit for average.

So naturally Giants’ GM Brian Sabean had to have him.

On Friday, the Giants acquired the 34-year-old former Royal, who is well known for having a poor clubhouse reputation. That’s something the close-nit Giants don’t need right now heading into a huge weekend series with the first place Padres (the team the Giants are trailing by 2.5 games in the NL West).

Clearly hypnotized by his 16 homers this season, Sabean felt the need to add the outfielder despite the fact that Guillen is more useless than a chair with only two legs. Plus, his acquisition means that Aaron Rowand, Travis Ishikawa (assuming Aubrey Huff moves back to first base) and Nate Schierholtz will receive less playing time than they already are, which is befuddling when you consider that Guillen isn’t a better option than any of them.

If I punch myself in the side of the head enough times and squint hard enough, I might see the need for Guillen as a pinch hitter. But there’s no way that the Giants actually believe this schmuck is a starter. Do you know how much ground there is to cover in right field at AT&T Park? Guillen would be an absolute train wreck and for what? A couple of home runs down the stretch? I thought that’s what Pat Burrell was for? Didn’t Sabean already acquire Pat Burrell already? I’m confused.

The worst part is, Sabean traded away two capable outfielders earlier this season in Fred Lewis and John Bower – two homegrown players that were better defensively than Guillen and who came with zero baggage. How does trading Lewis and Bowker and trading for Guillen make any sense? Tell me what the difference is between those players, or how Guillen makes the Giants better than Lewis and Bowker? And what happens to Schierholtz? The kid entered spring training as the favorite to start in right field and after a poor couple of weeks at the plate, he became Lewis’d, Bowker’d and Kevin Frandsen’d in the blink of an eye. If I were a Giants’ farm player, I’d want to be dealt immediately because Sabean will eventually block my position with a crusty old vet. It’s only a matter of time.

Sabean doesn’t have the slightest clue what it takes to build an offense. For every Burrell, Huff and Juan Uribe, there’s a Rowand, Edgar Renteria and Mark DeRosa (who clearly wasn’t healthy when Sabean decided to hand him a two-year deal this past offseason). For every Bengie Molina trade, there’s a Guillen, Ryan Garko and Freddy Sanchez deal right around the corner.

I’ve never see a man make so many stupid decisions and yet retain his job for 14 years. If Brian Sabean were the President of the United States, half the nation would be underwater right now.
