The MLB offseason period is usually a wild ride with lots of unexpected twists and turns, and so far this year it has been no disappointment. After a July 31 trade deadline left some teams wanting more, general managers wasted no time getting to the phones and striking deals once the postseason ended. The 2015 to 16 offseason has also included several debatably over-the-top contracts as teams have scrambled to fill their needs with the best possible options. Below are a few of the biggest moves so far:

Lefty ace David Price received a seven-year, $217 million deal with the pitcher-needy Boston Red Sox. The Red Sox are lucky to land Price, a familiar face in the batter-friendly American League East. After a couple of big-name free agent busts demoralized the Red Sox this past season, they are hoping that Price lives up to the hype. In addition, new GM Dave Dombrowski traded three prospects for former Atlanta and San Diego closer Craig Kimbrel. Kimbrel, like Price, is a major upgrade to a pitching staff that struggled mightily in 2015.

The New York Yankees matched their hated rivals by trading for 100 mph-throwing Aroldis Chapman. The dominance of Chapman should create a menacing back end of the Yankees bullpen, as he is set to join young studs Dellin Betances and Andrew Miller. However, barring this trade, the Yankees have had an uncharacteristically quiet offseason.

Reigning National League Cy Young runner up Zack Greinke landed a hefty six-year, $206.5 million deal with the Arizona Diamondbacks. The Greinke signing was the first of a flurry of moves made by General Manager Dave Stewart, who also made a controversial trade for former Braves’ starter Shelby Miller.

2015 World Series Champion Johnny Cueto left the Royals in favor of a seven-year, $130 million deal with the San Francisco Giants. Along with Cueto, San Francisco signed Jeff Samardzija, a hard-throwing sinkerballer who solidifies a pitching staff that already includes bonafide ace Madison Bumgarner.

Former Washington Nationals ace Jordan Zimmerman signed a five-year, $110 million deal with the Detroit Tigers. Zimmerman will join a rotation with big names such as Justin Verlander and Anibal Sanchez, trying to help the Tigers climb back into contention in the American League.

The Chicago Cubs, famous for their current 108-year World Series Championship drought, may be on the cusp of breaking that streak. General Manager Theo Epstein, who pulled the Red Sox out of their World Series curse, and Manager Joe Maddon have backed up the Cubs’ successful 2015 campaign with a monster offseason. The Cubs signed elite utility-man and all-around player Ben Zobrist, bolstered their already solid rotation with the always competitive John Lackey, and, most notably, took star outfielder Jason Heyward right out of the rival Cardinals’ hands. Between the young talent in players like Kris Bryant, Addison Russell and Kyle Schwarber, 2015 NL Cy Young winner Jake Arrieta, and a rejuvenated bullpen, expectations are sky-high for the Cubs.

After a drawn out and rather frustrating set of negotiations, Yoenis Cespedes took a discount and remained with the 2015 NL Champion New York Mets. After holding out for two months, the stingy Wilpon ownership group finally inked the Cuban star, who received many offers from other teams hoping to snatch his formidable power and arm. Alongside one of the best young pitching staffs in recent memory, the Mets should be looking forward to another run at the World Series.

The Tigers also inked another marquee free agent in outfielder Justin Upton. Having bounced around in the past couple seasons, Upton should stay put with his six-year, $132 million contract. Tigers fans will enjoy the idea Upton batting in the same lineup as Miguel Cabrera in the coming years.

Chris Davis, one of the premier power hitters in the American League, stayed in Baltimore with a seven-year, $161 million deal. The Orioles need Davis’ usual production to compete in the AL East.
