Metzger graduated high school from
Holy Cross of San Antonio and then attended
St. Edward's University. He was selected in the 1st round (16th overall) of the
1969 Major League Baseball draft by the
Chicago Cubs, and he made his debut for them a year later. Metzger won the 1973
Gold Glove Award at shortstop, the first one for an Astro at the position; no Astro shortstop would win a Gold Glove Award for the next 48 years. He led the
National League in triples in 1971 (11) and 1973 (14). He led the National League in outs (528) in 1972. On November 29, 1979, Metzger lost the tips of four fingers on his right hand (index to pinky) in an electric table-saw accident. He had been building a wooden playhouse for his children as a Christmas present. Metzger attempted a comeback for the 1980 season, but was released by the San Francisco Giants on August 10, 1980, after only hitting .074 in 28 games. Immediately after being released, he was re-signed by the Giants as a coach for the remainder of the season. In 11 seasons Metzger played in 1,219 games and had 4,201 at bats, 453 runs, 972 hits, 101 doubles, 71 triples, five home runs, 254 RBI, 83 stolen bases, 355 walks, .231 batting average, .291 on-base percentage, .293 slugging percentage, 1,230 total bases, 90 sacrifice hits, 22 sacrifice flies and 34 intentional walks. == Personal life ==
