The Yankees better land Cliff Lee or else they could be in a world of hurt next season.

Offensively, they’ll continue to be dangerous. Thanks to Alex Rodriguez, Mark Teixeira, Robinson Cano, Curtis Granderson, Derek Jeter, Nick Swisher and Jorge Posada, they won’t have to worry about scoring runs again next season (although it’s important to note that Jeter is coming off a career-low year and Posada struggled at the dish as well.)

But their offense wasn’t the reason they fell short of reaching the World Series: their pitching was. That’s why they set out this offseason to acquire Lee, but there’s no guarantee that they’ll be able to land him with the Rangers trying desperately to retain him.

After Jayson Werth and Carl Crawford each received seven-year contracts, the Yankees had no choice but to add another year to their offer for Lee. They wanted to stay at six years, but the Rangers have amped things up and are reportedly sending a contingent to Arkansas on Thursday in order to get Lee to re-sign. The Yankees had no choice but to take an at-all-costs approach in signing the 32-year-old ace.

Chances are Texas won’t be able to match New York’s final number, which is good for the Yankees. But Lee enjoyed playing with the Rangers last year and spoke after the World Series as though he was coming back. If Texas can get close to the Yankees’ asking price, then Lee may re-sign with the Rangers in order to stay in familiar surroundings.

That would be devastating for the Yankees, who now are suddenly looking up at the Red Sox in the AL East. Just this past week, Boston traded for slugger Adrian Gonzalez and signed Crawford to a whopping $142 million deal. Instantly the Red Sox have added power, speed and defense to their roster, all while the Yankees have impatiently waited for Lee’s answer. If they can’t sign Lee and they go into next year having to rely on A.J. Burnett being one of their top arms, the Bombers are in trouble.

They may want to add on an eighth year if that’s what Lee wants.

After they lost Jason Bay to free agency last winter, Boston’s offense looked about as dangerous as a ball-pit in a kid’s indoor playground. But after trading for Adrian Gonzalez and signing Carl Crawford to a massive seven-year contract, the BoSox have suddenly become the team to beat again in the AL East.

Gonzalez finished the 2010 season with a .298/.393/.511 batting line, 31 home runs and 101 RBI over 591 at-bats. And he posted those numbers at spacious PETCO Park, so one can only assume that he’ll have plenty of success hitting at smaller Fenway.

Crawford, who inked a whopping $142 million contract with the Red Sox late Wednesday night, battled .307 with 19 home runs and 47 stolen bases for the Rays last season. He immediately adds speed, defense and a little pop to Boston’s much-improved roster and should do incredibly well hitting in the same lineup as Gonzalez, David Ortiz and Kevin Youkilis.

Considering the Yankees have major pitching issues, the Red Sox have to love what they’ve been able to do this offseason. After they lost Victor Martinez to the Tigers, fans were worried that Theo Epstein may strike out this winter. Instead, he’s answered with the best offseason of any club and it’s not even the middle of December yet.

According to ESPN’s Buster Olney, the Red Sox and Padres have a greed to a deal that will send first baseman Adrian Goznalez to Boston in exchange for several top prospects.

The team flew in Gonzalez, who had surgery Oct. 20 on his right, non-throwing shoulder to clean up the labrum, for a physical examination Saturday. While there was no official word on the physical, a team source told ESPNBoston.com’s Joe McDonald that Gonzalez “looked good.”

The Red Sox continued Saturday night to work on a long-term contract with him, a source, who indicated that the negotiation window will close at 2 p.m. ET on Sunday, told ESPNBoston.com’s Gordon Edes.

In exchange, the Padres would receive three prospects in pitcher Casey Kelly, first baseman Anthony Rizzo and outfielder Reymond Fuentes, according to a baseball source. The Padres also would receive a player to be named later, a source told Edes.

This deal works for all parties involved. The Padres couldn’t/wouldn’t pony up to pay Gonzalez, so they needed to get something for him before he hit the open market in 2012. The Red Sox desperately needed to add another middle-of-the-order bat and Gonzo fits the bill. He should love that short porch in right field at Fenway, although this guy can hit it out to all sides of the field. (He should love hitting in that wind tunnel that the Yankees call a ballpark, too.)

The only thing that’s unfortunate is that the Padres’ offense was about as explosive as wet tuna last year and now they just traded away their best hitter. This is a club that relied heavily on pitching last year and they’ll have to do it again this season because their lineup is the definition of weak.

Of course, maybe management knew that their success last year was more fluke than anything and decided that it was now or never when it came to trading Gonzalez. They didn’t want to hang onto him just to finish fifth next year (I’m not saying they would have – I’m just delving into the thought process of San Diego’s brass) and lose out on the chance to acquire Rizzo, Kelly and Fuentes. So they made the trade and will now deal with the fan outcry.

SI.com’s Jon Heyman put together a list of the 20 best decisions made by MLB teams over the past year.

His No. 1 was the Nationals’ signing of Stephen Strasburg, while his No. 2 was the Cubs’ decision to trade Milton Bradley to the Mariners in exchange for pitcher Carlos Silva (who is leading the club in wins, ERA and WHIP).

Heyman’s No. 4 best decision involves a team that has been one of the bigger surprises so far this season:

4. The Padres’ decision not to trade Adrian Gonzalez and/or Heath Bell

Everyone assumed new Padres GM Jed Hoyer would want to make a big splash and set the team up for the future by trading All-Star 1B Adrian Gonzalez, who could bring a haul with his reasonable contract ($10 mil over two years) and big-time talent. Word supposedly was that Hoyer had an obvious landing spot in his old haunt in Boston, where Hoyer had been an assistant GM and knew the system. That assumption was supposedly bolstered by Padres marketing materials that allegedly omitted Gonzalez.

However, Hoyer and Padres decision-makers held both Gonzalez and top reliever Heath Bell, fortified the rotation by adding stable veteran Jon Garland and kept their fingers crossed. To everyone’s surprise — except maybe San Diego’s brass — the Padres have been at or near the top of the NL West all year. Hoyer didn’t disrupt what former Padres GM Kevin Towers built in San Diego to satisfy his ego. Instead, he did the prudent thing. Just because Towers was fired by new owner Jeff Moorad doesn’t mean he did a bad job. It turns out there were some very good pieces in place, including what appears to be the majors’ best bullpen.

There is still some concern in San Diego that the Padres will be sellers at the trade deadline, but if they stay in contention in the NL West it’s hard to envision that happening. This is just speculation on my part, but I have to believe that if Hoyer does make a big move (i.e. trading Gonzo and/or Bell), it won’t come until after the season.

Until then, the Padres’ current roster will have every opportunity to make a run at the postseason this year.
