 Biographical Information
 Amateur Career
Jay hit .466 as a high school sophomore, .528 as a junior and .380 with 15 steals as a senior. Going on to the University of Miami, he hit .368/.458/.513 with 56 RBI and 19 steals in 26 tries in 2004; he started every game in left field as a freshman. He hit a two-out, walk-off grand slam to beat Long Beach State on May 28. Both Baseball America and Collegiate Baseball named him a Freshman All-American. Jay then was 6 for 14 with a triple, homer and 7 RBI in the 2004 College World Series, making the All-Tournament Team.
As a sophomore, Jon batted .408/.490/.531 for the 7th-best average in Miami history. He was third in the Atlantic Coast Conference in average behind Shane Robinson and Aaron Bates and made first-team All-ACC in the outfield. He hit .262 with a team-high 15 runs and 7 steals with Team USA that summer; they did not play any major tournaments that winter.
Jay's batting line as a junior in 2006 was .361/.490/.520 to edge Jemile Weeks for the team lead in average. He was 31-for-38 in steals and scored 77 runs in 66 games. He was one steal and two runs behind Shane Robinson, the ACC leader, and tied for 6th in NCAA Division I in runs scored. He again was picked as an All-ACC outfielder.
Jay was immediately assigned to the Swing of the Quad Cities and hit .342/.416/.462 in 60 games for them, with 42 runs and 45 RBI. He would have led the Midwest League in average and OBP had he qualified. Baseball America rated him the #5 Cardinals prospect.
In 2007, Jon hit .235/.333/.373 in 26 games for the Springfield Cardinals but a right shoulder strain cost him a month. He was 1 for 2 for the GCL Cardinals on a rehab stint then batted .286/.321/.397 in 32 games for the Palm Beach Cardinals, missing another month with a left shoulder strain.
Jay was healthy for most of 2008, hitting .306/.379/.457 with Springfield and .345/.406/.500 in 16 games for the Memphis Redbirds before another left shoulder strain ended his season in August. He led the Texas League's outfielders in fielding (1.000) and was 8th in average, just ahead of teammate Allen Craig. Jay was rated the #16 prospect in the loop by Baseball America, between Will Inman and Kevin Jepsen.
In 2009, Jay spent all season with AAA Memphis, batting .281/.338/.394 with 20 steals in 28 tries and 72 runs. He made his first career error in the minors, fielding .996 in center. He was second among Cards farmhands with 142 hits (10 behind teammate Allen Craig) and 72 runs (6 behind Craig). Baseball America rated him as the top "Hitter for Average" in the St. Louis system.
Jay began 2010 with Memphis and was hitting .347/.420/.542 with 16 runs and 7 steals (not caught) in 17 games.
Jay was then called up to The Show to replace his longtime teammate and close comparison, Allen Craig, who was optioned down. He made his major league debut as a pinch-hitter for Kyle Lohse with a 3-0 deficit in the 6th against the Atlanta Braves on April 26, 2010. Facing Tim Hudson, the Floridian flyhawk struck out on three pitches. However, he quickly found his major league groove, hitting .300 in 105 games as a rookie. In 2011, he was the team's most used centerfielder as they won a World Series title, defeating the Texas Rangers in 7 games in the Fall Classic. He hit .297 in 159 games that year. He remained a starter and a solid contributor with the bat over the next three season, 2012 to 2014, playing in the postseason every year, including a return to the World Series in 2013, although they were defeated in six games by the Boston Red Sox that year. He hit between .276 and .305 those three years, and while he did not hit for much power, his OPS+ was always 100 or above, as he contributed with his batting average, ability to draw walks, and good baserunning.
Things took a downward turn in 2015 however, even though the Cardinals had the best record in the majors that season. He played only 79 games, and contributed only a .210 average, with 1 homer and 10 RBIs. He had only 1 at-bat in the postseason as the Cards were surprised by the Chicago Cubs in the Division Series. He no longer figured on the team's plans, and on December 8th, he was traded to the San Diego Padres in return for 2B Jedd Gyorko.
