📆 November 18, 1966: Koufax quits

58 years ago today, Sandy Koufax shocked the world by retiring at age 30, citing his painfully arthritic arm and fear of permanent damage.

“At that time, there was no surgery. The wisdom was that if you went in there, it was just going to make things worse. … Now you go in, fix it and you’re good for next spring.”

– Koufax

The big picture: While modern surgery may have extended Koufax’s career, there is something to be said for coming out on top. And few athletes have ever done it like Sandy.

According to the numbers: For the first six years of his career (ages 19-24), Koufax was a serviceable, if unspectacular, starting pitcher. Then he turned 25 and began perhaps the greatest era in MLB history.

• From 1961 until his retirement in 1966, Koufax went 129-47 with 115 complete games, a 2.19 ERA, 0.97 WHIP and 1,713 strikeouts against only 412 walks.

• He also threw a then-record four no-hitters (including one perfect game) while winning five ERA titles, three Triple Crowns, three Cy Youngs, two World Series MVPs and the 1963 NL MVP.

The last word: Willie Stargell, the Pirates Hall of Famer who managed just two hits in 23 at-bats against Koufax, said it best: “hitting Sandy Koufax is like drinking coffee with a fork.”

📺 Watchlist: The Battle for the Lone Star State

The Cowboys host the Texans this evening (8:15 PM ET, ESPN/ABC/ESPN2) in a game between the NFL’s two Texas teams.

Head to head: Dallas leads the all-time series 4-2, but first-place Houston* clearly has the upper hand this year against a reeling Cowboys team that has lost four straight and will start the rest of the season without QB Dak Prescott ( hamstring).

More to watch:

• ⚽️ CONCACAF Nations League: USMNT (1-0 lead) vs. Jamaica (8 p.m., TNT) … Quarter-final second leg.

• 🏀 NBA: Rockets at Bucks (8 p.m., NBA); Warriors at Clippers (10:30 p.m., NBA)

• 🏒 NHL: Avalanche at Flyers (7 p.m., NHL)

• 🏀 NCAAM: No. 4 Gonzaga, San Diego State (10 p.m., CBSSN)

*Looking for a rebound win: The Texans have lost three of four since their 5-1 start. The Cowboys – who have scored at least 27 points in four straight games – may be just what the doctor ordered.
