Long before analytics made on-base percentage a key indicator of offensive skill, Mike Hargrove mastered patience at Arlington. Known as "The Human Rain Delay," the left-handed first baseman gained his nickname due to his highly ritualistic routine between pitches—adjusting his helmet, tightening his batting gloves, and wiping his shoes—which disrupted the timing of opposing pitchers.

Hargrove entered Texas as a relatively unnoticed 25th-round draft pick from Northwestern Oklahoma State but quickly proved his talent. He started his career with an outstanding 1974 season, hitting .323 with a .395 on-base percentage, earning the American League Rookie of the Year Award and becoming a key part of the Rangers’ improving lineup. He continued his success in 1975, earning an AL All-Star selection by batting .303 and leading the team with 91 runs scored, demonstrating consistent offensive prowess.

While Hargrove didn't possess the towering home run power typically seen in corner infielders, his skill at controlling the strike zone was exceptional. He exemplified high-leverage patience, using his sharp vision to tire out pitchers and leading the American League in walks twice while with Texas—racking up a career-high 114 free passes in 1977 and 101 in 1978. During his five full seasons with the Rangers, he maintained a remarkable .399 on-base percentage, making him a persistent and frustrating presence on the bases for anyone trying to get through the lineup.

That productive residency ended unexpectedly before the 1979 campaign, when the Rangers traded him to San Diego in a multi-player blockbuster. Hargrove then spent a successful decade with the Cleveland Indians as a player and manager, but his peak was in Arlington.

Over his six seasons in the Lone Star State, Hargrove had 795 hits, 126 doubles, 51 home runs, and 338 RBIs while generating a .291/.399/.403 slash line (131 OPS+) and drawing 500 walks.
