Jay was a National High School Player of the year candidate in 2005. On average, Jay had 30 scouts per game his senior year.
In addition to his three All-Star selections (2011, 2012 and 2016) during a 10-year major-league career, Jay has won two Silver Slugger Awards (2012, 2013) and hit 263 home runs as a right fielder – tied (with Giancarlo Stanton) for the most by any right fielder in Major League Baseball since 2008. His 800 RBI since 2008 lead all major-league right fielders while his 91 outfield assists during that span are the most in the majors for an outfielder. Since 2010, Jay has seven seasons of 25 or more home runs – tied for the most in the majors with Adam Jones of the Baltimore Orioles. In 2017, Jay hit a career-best 36 home runs and drove in over 100 RBI (101) for the second time in his career in 146 combined games between the New York Mets and Cleveland Indians. In five games during the ’17 American League Division Series with Cleveland, he went 5-for-18 (.278) with one double, two home runs and four RBI. On August 1, 2016, Jay became the first player traded during the season while leading the league in RBI since the stat became official in 1920 when he was acquired by the Mets from the Cincinnati Reds. He signed a three-year contract to return to the Mets as a free agent on January 16, 2018.
On May 28, 2008, Jay became the first major-league player to reach base in the first six plate appearances of his career.
