The Washington Nationals reportedly offered free-agent outfielder Bryce Harper a 10-year deal worth $300 million.According to Chelsea Janes of theWashington Post Ronald Acuna Jr. Jersey , that offer did not include any opt-out clauses.Ken Rosenthal of The Athletic noted the Nats likely knew Harper wouldn't accept the offer, and he mentioned Washington as a "fallback" for Harper if he doesn't get the deal he wants.Rosenthal added that Harper is hoping to receive a bigger contract than the 13-year, $325 million deal New York Yankees slugger Giancarlo Stanton signed with the Miami Marlins in 2014.Last year, an anonymous MLB general manager suggested to ESPN.com'sEddie Matzthat Harper could land a $400 million contract in free agency.On Tuesday, Nationals GM Mike Rizzo toldESPN.comthat Washington isn't giving up on bringing Harper back into the fold:"We've had conversations and we utilized our exclusivity to negotiate with him late in the season through when he became eligible to sign with a team. We didn't get anything done, but he's a guy that is near and dear to us and we are not closing any doors."The 26-year-old Harper is coming off his sixth All-Star nod in seven MLB seasons after he hit .249 with 34 home runs and 100 RBI in 2018.While Harper's batting average left something to be desired, he walked an MLB-leading 130 times and posted an on-base percentage of .393 http://www.bravesfanproshop.com/authentic-sean-newcomb-jersey , good for ninth in the majors.Harper made his MLB debut in 2012, just two years after the Nationals selected him with the No. 1 overall pick in the MLB draft.He was named the National League Rookie of the Year, and three seasons after that, he won the National League MVP Award when he hit .330 with 42 homers and 99 RBI.In 927 career games, Harper is hitting .279 with 184 home runs and 521 RBI.Because of his age and impressive resume, Harper is seemingly in line to land a record-breaking contract. His agent, Scott Boras Preston Tucker Jersey , has the reputation and skills to get him that sort of deal.Harper leads a strong free-agent class that includes shortstop Manny Machado, starting pitcher Dallas Keuchel, closer Craig Kimbrel and several other top-flight options. Dustin Bradford/Getty ImagesThe Washington Nationals' ownership group "refused to approve" a trade involving Bryce Harper the day before MLB's July 31 non-waiver trade deadline, The Athletic's Ken Rosenthal reported Saturday.According to Rosenthal, the Nationals had a preliminary agreement in place with the Houston Astros before the deal was scuttled.Rosenthal wrote the Nationals would've received minor league pitcher J.B. Bukauskas. The right-hander is the No. 8 prospect in the Houston minor league system, per MLB.com, and finished 4-2 with a 2.14 ERA in 14 appearances across five levels.Two other prospects would've joined Bukauskas in the trade.Rosenthal reported the Nationals owners decided against trading Harper because they "feared that trading him would harm their relationship with the player and reduce their chances of signing him."It's impossible to say whether Harper's presence would've resulted in a different outcome in the American League Championship Series. The Boston Red Sox defeated the Astros in five games http://www.oriolesfanproshop.com/authentic-j.j.-hardy-jersey , scoring 27 runs as they reeled off four straight victories to claim the AL pennant. Boston succeeded in attacking the Houston pitchers, so Harper may not have changed anything.The Astros weren't the only World Series contender to make a play for Harper. The Los Angeles Times' Jorge Castillo reported Wednesday the Los Angeles Dodgers offered Yasiel Puig in a trade package to no avail.The Washington Post's Chelsea Janes reported Wednesday the Nationals offered Harper $300 million over 10 years in late September but that the 26-year-old turned it down.If Harper signs elsewhere, then Rosenthal's and Castillo's reports could put more heat on the Nationals. Losing Harper would be a tough blow for the franchise, and the fanbase may grow even more frustrated with the knowledge Washington could've flipped Harper for prospects or an everyday MLB outfielder. If he departs, the Nats would only get back a compensation draft pick.
