Mills spent six years as the bench coach of the Red Sox prior to being hired as Astros manager in 2010 and called Pesky a friend. Pesky spent the majority of his baseball career in Boston and remained a fixture at Fenway Park long after his playing days.
"The six years I was there, whether it was Spring Training or during the season, you would always sit down and visit with Johnny, because he's always got some stories to tell you about the game," Mills said. "He had a lot of knowledge about the game for playing the field and his time on the infield with Ted [Williams] and Babe [Ruth]. It's sad, but at the same time, it brings back a lot of reflection."
Pesky broke into the big leagues with the Red Sox in 1942 and batted .331 with 205 hits, finishing third in American League MVP voting. He missed three seasons due to military service during World War II and came back to record 208 and 207 hits in 1946 and 1947, respectively, and was named to his only All-Star Game in 1946.
He finished his 10-year Major League playing career as a .307 hitter with 404 RBIs, 867 runs and 1,455 hits. He managed the Red Sox from 1963 to 1964 and in 1980, and was associated with the franchise in numerous other capacities. His No. 6 is retired.
"You'd see him just about every game, in the clubhouse and dugout, and you'd sit down and chat with him," Mills said. "It was kind of cool."
