<human>: Answer by taking a quote from the following article:

Simmons was born in Milwaukee and grew up as a fan of the Philadelphia Athletics. In the fourth grade, he received a spanking from his father for insisting that he wanted to play professional baseball. When he persisted in asserting his desire to be a baseball player, his father replied that he had better become a good player. Simmons was known by his birth last name (Szymanski) until he was playing for a local minor league team and he was tired of hearing people mispronounce it.

In his second season with Philadelphia (1925), Simmons led the AL with 253 hits with a .387 batting average, 24 home runs and 129 runs batted in (RBI). He scored 122 runs, hit 43 doubles, and finished with a .599 slugging percentage. His 85 multi-hit games constitute a single-season MLB record. He earned the second-most votes for the league's Most Valuable Player Award. In the following three seasons, he hit .341, .392 and .351 and drove in 109, 108 and 107 runs in those respective years, while finishing fifth in 1926 MVP voting and fourth in 1927.  Simmons led the A's to the AL pennant in 1929 as Philadelphia went 104-46, finishing 18 games ahead of the New York Yankees. The A's went on to defeat the Chicago Cubs in five games to win the World Series. That season he hit .365 with 34 home runs and led the AL with 157 RBI. He also scored 114 runs, had 212 hits with 41 doubles and a .642 slugging percentage. In his first World Series Simmons batted .300 with 2 home runs, 5 RBIs and scored 6 runs.  Simmons' best year as a player was in 1930, when he won his first of successive batting titles, hitting .381 with 36 home runs, 211 hits, 41 doubles and 16 triples. He had a slugging percentage of .708, drove in 165 runs and scored 152 runs in 138 games. The A's won the AL pennant again, going 102-52, and defeated the St. Louis Cardinals to win back-to-back World Series titles. In that World Series, Simmons batted .364 with 2 home runs, 4 RBI with a .727 slugging percentage.  In 1931, the A's won their third straight AL pennant, by 13.5 games over the Yankees, going 107-45. Simmons won his second batting title, hitting .390 with 22 home runs, 128 RBI, 100 runs scored, 200 hits, 37 doubles, 13 triples and a .641 slugging percentage while playing in only 128 games. He finished third in AL MVP voting behind the MVP (teammate Lefty Grove) and the Yankees' Lou Gehrig. The A's were upset in their quest for a third consecutive World Series title, losing the World Series in seven games to the Cardinals. Simmons hit .333 with 2 home runs and 8 RBI in the series.  In a final season with Philadelphia, Simmons led the AL with 216 hits. He batted .322, with 35 home runs, 151 RBIs and 144 runs scored in 1932. Simmons finished his Philadelphia Athletics tenure with a .356 batting average, 209 home runs, 1,178 RBI and 969 runs scored in 1,290 games. He drove in 100+ runs in all nine seasons and scored 100 or more runs in five seasons. In three World Series appearances for the A's, Simmons hit .333 with 6 home runs, 17 RBI and 15 runs scored in 18 games. CANNOTANSWER
