The 1957 season marked ten years since the Braves won a pennant. In 1948 they lost to Cleveland and were still in Boston. They moved in the early 1950s to Milwaukee and built a powerhouse. In 1957 they finally reached first place in the National League. It was their third championship of the century (1914 and 1948).

Fred Haney
The Braves were led by Fred Haney who had a short playing career in the 1920s, then went into coaching. He’d been a not particularly successful manager never finishing higher than sixth when, in 1956, he took over the Milwaukee team. He led them to second place and broke through the next year with 95 wins. The Braves led the NL in runs, triples, home runs, total bases, and slugging. They were second in hits, average, and OPS; third in OBP. In an eight team league they were next to last in stolen bases. The staff gave up the least home runs in the league while finishing second in hits and ERA. They were second in run scarcity, but they were next to last in walks.
The Braves infield changed during the season. The most important change was the addition of second base Hall of Famer Red Schoendienst from the Giants. He solidified the middle of the infield, added veteran leadership to the team, and gave Milwaukee a top part of the order hitter (he did a lot of leading off). He hit .310 with an OBP of .348, tops behind the big power hitters. His 3.9 WAR was fourth among everyday players. Johnny Logan was his middle infield mate. Logan hit .273 with 10 home runs and 135 hits. He was a competent shortstop whose 4.1 WAR was third among the hitters. Second among the hitters at 7.4 WAR was Hall of Fame third sacker Eddie Mathews. He hit .292, had 94 RBIs, 32 home runs, 167 hits, and scored 109 runs. First base was supposed to be a platoon position with Joe Adcock being the big slugger and hitting right-handed while Frank Torre (Joe’s brother) hit lefty and was a much better fielder. The problem was that Adcock broke his leg and was reduced to playing in only 65 games. He hit .287 with 12 homers and 38 RBIs. Torre, forced to do most of the work at first hit .272, but with only five home runs and 40 RBIs in almost exactly twice as many games. The bench wasn’t particularly strong. Danny O’Connell (who Schoendienst replaced as the starter) and Felix Mantilla both hit in the .230s and had five home runs between them. At first, the Braves had Nippy Jones to replace Adcock he hit .266 and, much to the Yankees regret, had a penchant for shining his shoes.
When the season started, the outfield was supposed to be set. It turned out it wasn’t. Right field was secure in Henry Aaron. The Hall of Famer hit .322, had 44 home runs, 132 RBIs, a .600 slugging percentage, and led the team in WAR at 8.0. That earned him the National League MVP Award for 1957. The problem was the other two spots. Billy Bruton was supposed to be the regular center fielder and the leadoff man, but he banged up his knee and only got into 79 games. He still managed to lead the team with 11 stolen bases. Needing a new outfielder, the Braves shifted Aaron to center and brought up a career minor leaguer named Bob “Hurricane” Hazle. He became one of the greatest (and most famous) “90 day wonders” ever. In 41 games he hit .403 with seven home runs, 27 RBIs, 26 runs scored, 87 total bases, an OPS of 1.129, an OPS+ of 209, and 1.9 WAR (which is pretty good over only 41 games). The other problem was left field. Bobby Thomson of “The Giants Win the Pennant” fame and Andy Pafko of “The Boys of Summer” fame were sharing time. Together they had 12 home runs, 50 RBIs, and hit around .250. Haney decided to go with second year man Wes Covington to solve his left field problem. Covington responded with a .284 average, 21 home runs, 65 RBIs, and 2.6 WAR. In addition to these six, the Braves got 28 games and six RBIs out of 28-year-old Chuck Tanner. He went on to lead the “We Are Family” Pirates to the 1979 World Series as manager.
Three men did most of the catching. The regular was Del Crandall. He hit only .253, but had 15 home runs, 46 RBIs, a .718 OPS, and 1.6 WAR. The backups were Carl Sawatski and Del Rice (making the Braves probably the only team ever to have two catchers named Del–I didn’t check). Between them they equaled Crandall’s 15 home runs (with Rice having nine of the 15), but only 37 RBIs.
They caught a staff that used five men to make a four man rotation. The star and ace was all-time winningest left-hander and Hall of Famer Warren Spahn. He pitched 39 games (35 starts), went 21-11, had an ERA of 2.69, had a 1.177 WHIP, an ERA+ of 130, and 4.6 WAR. Sort of your standard every season Spahn year. Lew Burdette was the second pitcher amassing a 17-9 record with a 3.72 ERA with only 78 strikeouts. Bob Buhl was the third starter. His record was 18-7 with an ERA of 2.74 and 2.9 WAR. To cover the fourth hole the Braves used Gene Conley and Bob Trowbridge. They pitched a total of 67 games, starting 34 (about half). Conley was, at the time, about equally famous as one of the last two sport stars because he played for the Boston Celtics basketball team when not on the mound. He was 9-9 while Trowbridge was 7-5 (a combined 16-14, not an untypical record for a fourth pitcher). The Closer was Don McMahon. He was, with 47 innings over 32 games, something like a modern Closer (which wasn’t that typical in the era). His ERA was 1.54, he had 46 strikeouts in the 47 innings, and produced 1.7 WAR. Later Reds stalwart Joey Jay, at age 21, got into one game for Milwaukee. He got a save.
The Yankees may have been favored, but the Braves were a formidable team. Aaron was a rising star, Mathews already a star, and Spahn an icon. As an aside, I considered, when I was much younger, the Braves the best team up and down the roster that I ever saw (I go back to the early 1950s). Not sure that’s true any longer, but they were one of the teams that had both hitting and pitching to go along with good fielding and a bench.
