It took 26 years of suffering through the travesties of 58 catchers, but the Cubs feel they have finally found a replacement for Gabby Hartnett. Gone, they feel, are the days of Cuno Barragan, Johnny Pramesa, Roy Easterwood and other forgettable Cub catchers, for now they have 24-year-old Randy Hundley. Herman Franks, the Giant manager and one of Leo Durocher's best friends, gave Leo the tip-off on Hundley, "He can catch, he can throw and he can run, but he couldn't hit me if I walked in front of him." Since Durocher needed a defensive catcher, he acquired Hundley in a trade with the Giants last winter. Soon after the season began, however, Hundley was benched, not for poor hitting—which he was also guilty of—but because of poor throwing. Hundley threw hard all right. The trouble was, infielders covering second base on steals had to perform like pass-catching ends to grab his scatter-arm throws. Hundley worked hard on his throwing, returned to the lineup, and since then his on-target pegs to second have caught Maury Wills and Lou Brock stealing three times each. What's more, he began hitting. In his first 15 times up last week, Hundley had 10 hits, including four homers, and 10 RBIs. In one game against Houston he hit for the cycle. The spree left him with a .264 average and 16 home runs, establishing him as the best rookie catcher in the majors. It is doubtful whether Herman Franks would risk walking in front of him now.
