Tom Seaver has been diagnosed with dementia Jeff Keppinger Jersey , his family confirmed.According to the Los Angeles Times' Bill Shaikin, Seaver will remain active at his personal vineyard "but has chosen to completely retire from public life."Seaver played 20 years in MLB, including 12 with the New York Mets. He was a 12-time All-Star and won the National League Cy Young Award in 1969, 1973 and 1975.The 74-year-old is by far the most legendary pitcher in Mets history. He's the runaway leader in WAR (76.1), with Dwight Gooden a distant second (41.6), according toBaseball Reference. He's also first inERA (2.57), wins (198), strikeouts (2 http://www.whitesoxfanproshop.com/authentic-paul-konerko-jersey ,541), complete games (171) and shutouts (44).Seaver also played for the Cincinnati Reds, Chicago White Sox and Boston Red Sox. He retired after the 1986 season and was inducted into the Baseball Hall of Fame in 1992.Seaver washospitalizedfor Lyme disease in 1991. TheNew York Daily News'Bill Maddenreported in March 2013 that Seaver had been dealing with symptoms of the disease, such as memory loss and speech problems.When the Mets hosted the MLB All-Star Game at Citi Field in 2013, Seaver was on hand to throw out the ceremonial first pitch. John McCoy/Getty ImagesThe Boston Red Sox have reportedly added a four-time All-Star prior to Tuesday's non-waiver trade deadline.On Monday, Ken Rosenthal of The Athletic reported the American League East leaders acquired second baseman Ian Kinsler from the Los Angeles Angels. Jon Heyman of Fancred reported on the return package, noting the Angels received pitchers Williams Jerez and Ty Buttrey.According to Rosenthal, Los Angeles also provided the Red Sox with $1.8 million of the remaining $3.6 million Kinsler is owed this season.Heyman speculated this move suggests Boston is concerned with second baseman Dustin Pedroia James Shields Jersey , who has played a mere three games this season. Boston manager Alex Cora didn't rule out a 2018 return for Pedroia even though he underwent cartilage restoration surgery on his knee before the season and is on the disabled list with knee inflammation, per Lauren Campbell of NESN.Even without Pedroia, the Red Sox have built a healthy lead in the American League East and are six games ahead of the New York Yankees.Adding Kinsler only makes Boston stronger, including on the defensive side. He won a Gold Glove in 2016 and is responsible for 10 defensive runs saved this season, per FanGraphs.Offensively, Kinsler is slashing .239/.304/.406 with 13 home runs and 32 RBI. Those aren't the type of numbers indicative of much of his career, which features five seasons with at least 20 home two with more than 30 from when he was on the Texas Rangers.Still, Chad Jennings of The Athletic noted Kinsler is a worthwhile addition even with a dip in offensive production:Chad Jennings chadjennings22Ian Kinsler to the Red Sox first reported by Ken_Rosenthal. Kinslers offensive numbers are down http://www.whitesoxfanproshop.com/authentic-paul-konerko-jersey , but still a higher WAR this season than every Sox position player except Betts, Benintendi, Martinez and Bogaerts. And he has an .859 OPS since May 28.As for the Angels, they are in fourth place in the American League West and at least ensured a return package with Kinsler set for unrestricted free agency following the season.Boston has its eye on a playoff berth and more, and Kinsler gives it a postseason-experienced veteran (37 playoff game appearances) who can help anchor the infield defense and provide timely hitting.
