Mike Trout
On April 17, 2015, Trout became the youngest player in MLB history to reach 100 home runs and 100 stolen bases. He was 23 years and 253 days old when he reached the milestone, passing the previous record-holder, Alex Rodriguez, who had achieved it at the age of 23 years and 309 days in 1999. Trout led off the 2015 MLB All-Star Game with a home run, becoming the fourth player in All-Star Game history to do so. For the second year in a row, Trout won the All-Star Game MVP Award, becoming the first player ever to win it in consecutive years. On September 22, Trout hit his 40th home run, becoming only the second Angels player to hit 40 home runs in a season. Trout led the AL in WAR for the fourth straight year.
Iván Rodríguez
Making his debut with the Texas Rangers on June 20, 1991, he became the youngest player to catch in a major league game that season at 19 years of age. He immediately established himself as an excellent hitter who was also proficient in throwing out would-be base-stealers. No other catcher in the past 35 years has been as successful at this aspect of the game, with Rodríguez throwing out 48% of attempted basestealers through May 2006. He started many of the Rangers games at the end of the season, including 81 of the last 102. Rodríguez became the youngest player in the history of the Texas Rangers to hit a home run, on August 30, 1991, facing the Kansas City Royals and right-hander Storm Davis. He was named to the Major League Baseball (MLB) Rookie All-Star team by both Topps and Baseball America and finished in fourth place in the AL Rookie of the Year voting. He also placed first in throwing out runners, catching 48.6 percent of runners attempting to steal.
