changes to the stadium. The 1955 Senators posted a 4.62 staff earned run average; one year later, the staff ERA jumped to 5.33—with an abysmal 5.55 ERA at home. To Griffith's credit, however, his pitching staff (led by ace right-hander Camilo Pascual) began to post respectable earned run averages beginning in and by , the Senators' ERA was down to 3.77 (3.88 at Griffith Stadium). Calvin Griffith also invested in Washington's traditionally weak farm system and scouting operations. In , The Sporting News' Official Baseball Guide showed only three full-time scouts on the Senators' org chart, although one of them was Joe Cambria, who established a pipeline of playing talent from Cuba to the franchise that endured until his death in 1962. The TSN Baseball Guide listed eight scouts on the Senators' staff. But by 1960, the team's last year in Washington, the same annual listed 23 full-time talent hunters working on the Senators' behalf. The changes to the farm system were less dramatic. Historically, Clark Griffith's farm system was concentrated on low-level minor league teams. For years, Double-A Chattanooga was Washington's top farm team, and for a time the Senators had only two other farm teams, Class B Charlotte and Class D (equivalent to a Rookie-level team in today's system) Orlando. Calvin added Triple-A affiliates, first in 1956 and then, for good, in 1960. Even then, the team usually fielded 6–8 affiliates throughout the 1950s, and the 1960 Senators actually sponsored one fewer team than the 1951 club. Griffith also began to invest, cautiously, in bonus babies, with Killebrew a notable success. The proof of his endeavors was in the pudding: by 1960, his Senators featured home-grown players like Killebrew, Allison, Pascual, Pedro Ramos, Jim Kaat (elected to the Hall of Fame in 2021) and Zoilo Versalles. He also obtained young talent like Earl Battey, who was the team's starting catcher from 1960 to 1967, and power-hitting prospect Don Mincher, both acquired for Sievers in April 1960, and starting pitcher Jack Kralick, signed as a minor league free agent the previous season. The trio came to Washington from the White Sox. Off the field: Relocation efforts But the results of Griffith's efforts were initially hard to detect. The 1956–59 Senators averaged 95 losses each season, with three last place finishes in a row (1957–59). Attendance hovered below 500,000 until 1959, when it improved to 615,000. The move of the
