Yu Darvish's frustrating 2018 has come to an abrupt end due to an elbow injury.

Per The Athletic's Sahadev Sharma http://www.yankeesfanproshop.com/authentic-austin-romine-jersey , an MRI showed Darvish has a stress reaction in his right elbow and a triceps strain. He is going to be shut down for six weeks and won't pitch again this season.This comes after Darvish left a rehab start with Low-A South Bend on Sunday after one inning because of discomfort in his pitching arm.The Cubs signed the 31-year-old to a six-year contract in the offseason, hoping he would play a big role in their quest to get back to the World Series after winning a title in 2016.Instead, the four-time All-Star stumbled out of the gate with a 4.95 ERA in eight starts. He's also had two stints on the disabled list in 2018. The first came in early May due to a virus and again on May 27 with tendinitis in his right triceps.Because of Darvish's extended absence already this season, Cubs manager Joe Maddon won't have an issue forming a rotation without the right-hander. They acquired Cole Hamels from the Texas Rangers on July 27 to add depth to a group that includes Jose Quintana, Jon Lester, Kyle Hendricks and Tyler Chatwood. The New York Yankees have signed shortstop Troy Tulowitzki to a one-year contract for the league minimum pending a physical, according to Jeff Passan of ESPN.comFree agent shortstop Troy Tulowitzki is in agreement on a deal with the New York Yankees pending a physical Reggie Jackson Jersey , league sources tell ESPN. Tulowitzki is expected to join the Yankees on a league-minimum deal, with the Toronto Blue Jays paying the remainder of his $20 million salary.— Jeff Passan (@JeffPassan) January 2, 2019Tulowitzki was released by the Toronto Blue Jays earlier this offseason, and they'll pay out the remaining $38 million on his contract. Thus, signing for the minimum wasn't going to be a problem for 'Tulo', who now gets the chance to play for a championship contender.As Passan noted, Tulowitzki will play shortstop while Didi Gregorious recovers from Tommy John surgery. The Yankees hope to have Gregorious back at some point in the 2019 season http://www.yankeesfanproshop.com/authentic-bernie-williams-jersey , but adding a veteran in Tulowitzki gives them valuable insurance for the time being.advertisingA five-time All-Star, Tulowitzki has been slowed by injuries over the last two seasons. A severe right ankle injury limited Tulowitzki to 66 games during the 2017 season. A bone spur in the same ankle forced Tulowitzki to miss all of 2018 as well, and the Jays simply decided it was time to move on. Credit: Kim Klement-USA TODAY SportsThough Tulowitzki's batting stats have declined significantly since his trade to Toronto in 2015, he remains one of the game's elite defensive players. Tulowitzki is a two-time Gold Glover and promises to shore up the Yankees' infield until Gregorious returns. That is, of course, if he can stay healthy.advertisingIt's been a busy offseason for GM Brian Cashman, who traded for left-handed pitcher James Paxton from the Seattle Mariners and re-signed J.A. Happ to a two-year contract. Now C.C. Sabathia Jersey , he adds a potential future Hall of Famer at a discounted price.What This MeansIt's a low-risk, high-reward move for the Yankees. They add a reliable veteran who can be a complete difference maker if healthy. It's a cheap one-year deal, so there is absolutely no risk in giving Tulowitzki a chance. As for the 34-year-old, he now gets that chance at winning a World Series after falling short with both the Blue Jays and Colorado Rockies.advertising
