Ramirez owns a .300 career batting average with 148 home runs and 482 RBI in 945 games over eight Major League seasons with the Red Sox (2005) and Marlins (2006-12). The 28-year-old started three consecutive All-Star Games at shortstop for the National League from 2008-10 and took home back-to-back Louisville Silver Slugger Awards at the position in 2008 and 2009, when he won the NL's batting title with a .342 average.
Since his first full season in 2006, Ramirez leads the NL with 666 runs scored and ranks among the league leaders in batting average (.300, 9th), hits (1,103, 2nd), doubles (232, 3rd), home runs (148, 16th), on-base percentage (.374, 15th) and slugging percentage (.499, 20th).
The 6-foot-3, 225-pounder was named the National League Rookie of the Year in 2006 with Florida and has finished in the Top 10 of the NL's MVP voting twice in his career, including a second place finish in 2009. In 18 career games at Dodger Stadium, Ramirez is batting .388 (26-for-67) with three home runs and a .467 on-base percentage.
After playing exclusively at shortstop through the first seven seasons of his career, Ramirez transitioned to third base this season and was hitting .246 with 14 home runs and 48 RBI through 93 games with Miami. Ramirez was originally signed by Boston as a non-drafted free agent out of the Dominican Republic in 2000 before being traded to the Marlins as a part of six-player deal in November of 2005 that netted Boston Josh Beckett.
Choate has a 2.49 ERA in 44 relief appearances with the Marlins in his 12th Major League season.

Choate has allowed just three extra-base hits while striking out 27 in 25.1 innings this season.
"Randy Choate is a veteran pitcher that provides depth to our bullpen and gives Don Mattingly another left-handed relief option," said Colletti.
Over the course of his career, the Texas native has limited opponents to a .232 average, including a .203 mark against lefties, and posted a 4.01 ERA with the Yankees (2000-03), Diamondbacks (2004-07), Rays (2009-10) and Marlins (2011-12). Choate won a World Series ring as a member of the 2000 Yankees and has a 2.84 ERA in seven career postseason appearances.
