Phillies: Top individual seasons in team history by age
Age 36: Marlon Byrd (2014)
After hitting .229 in 35 at-bats with the Phillies in 2002, Byrd finished fourth in the Rookie of the Year vote in 2003, hitting .303 with 27 doubles, seven home runs and 11 stolen bases. After a less than stellar 2004 season, Byrd was traded to the Nationals for Endy Chavez.
Two mediocre seasons in Washington followed before Byrd was sent to the Rangers, where he posted a solid 43 doubles, 20 home runs and 89 RBI in 2009. Byrd made his lone All-Star appearance the following year with the Cubs and launched 24 home runs combined with the Pirates and Mets in 2013.
Returning to the Phillies via free agency for the 2014 season, Byrd posted a career-high in home runs with 25. He also hit 28 doubles, had 85 RBI and provided solid defensive play in right field. The 36-year old was near the end of a well-traveled career, but put together one of his finest in 2014.
After short stints in Cincinnati, San Francisco, and Cleveland, Byrd retired with a .275 average, 1534 hits and 159 home runs.
Age 37: Jim Eisenreich (1996)
Eisenreich saw limited action with the Twins from 1982-1984 and was out of baseball in 1985-1986 due to Tourette’s Syndrome. He returned the baseball in 1987 and spent the next six seasons in Kansas City before being signed by the Phillies as a free agent on January 20, 1993.
A member of the NL Champions in 1993, Eisenreich began the best four-year stretch of his career. He quickly became a fan favorite due to his humble nature and pure hitting ability. Eisenreich hit .318 with seven home runs and 54 RBI following by a .300 season in 1994 and .316 with 10 home runs in 1995.
At age 37 in 1996, Eisenreich posted his best all-around season, hitting a gaudy .361 with 24 doubles, 41 RBI, 11 stolen bases and only 32 strikeouts in 338 at-bats. He was granted free agency and signed with the Marlins where he would play for a little over a season before retiring with the Dodgers in 1998. Eisenreich continued to be a fan favorite, receiving standing ovations every trip back to Philadelphia in a visiting uniform.
In four seasons with the Phillies, Eisenreich batted .324 and retired with 1160 hits and a .290 average.
