Aaron hit a single off Cincinnati Reds rookie Wayne Simpson in the second game of a doubleheader as the Atlanta Braves lost 7-6 at Crosley Field on May 17, 1970.
Mays singled off Montreal’s Mike Wegener for his milestone hit as the San Francisco Giants won 10-1 over the Expos at Candlestick Park on July 18.
Now 11th on the all-time hit list, Mays produced 3,283 hits. Mays was the first player to hit over 600 homers and have 3,000 hits. Aaron would later join him and then become the only player to hit over 700 long balls and 3,000 hits.
One of the unique things about the Aaron-Mays connection in the same season is that they are not alone in achieving 3,000 hits in the same year. It’s actually happened five other times in baseball history.
Here is the list of players who joined the 28-member 3,000-hit club in the same season:
1970 — Hank Aaron (3,771) and Willie Mays (3,283)
A note about Gwynn and Boggs: Gwynn picked up his hit on Aug. 6, 1999, while Boggs accomplished the feat one day later.
The Pitchers: Simpson ended 1970 with a 14-3 record, but was later injured and didn’t finish the season as the Reds won the National League pennant. Wegener was only in the major leagues in 1969 and 1970. He was 3-6 in 1970 and 8-20 in his career.
