Milestone week, by the numbers

A few numbers to throw out there from this week in Major League Baseball:

1: Instant replay challenge. The first in baseball history came Wednesday when Alex Rodriguez's ninth-inning home run went over the fair-foul pole in left field at Tropicana Field. It was called a homer and confirmed as the Yankees beat the Rays.

1: Hit allowed by Milwaukee's CC Sabathia in his win Aug. 31, affirming the official scoring decision on an infield hit by the Pirates' Andy LaRoche.

20: Wins for Cliff Lee against two losses this season after throwing a shutout Monday against the Chicago White Sox. Exactly one year ago from the day, he was called up from the minors after an injury-plagued 2007. He's only the AL's fifth 20-game winner since 2004, and he did it with four weeks left in the season. He's also the eighth pitcher since 1920 to win 19 of his first 21 decisions in a season, according to Stats LLC. The last to do it was Roger Clemens, who was 20-1 with the Yankees after a win on Sept. 19, 2001. No big-league pitcher in history has won 20 or more games while losing two or fewer. Clemens lost his last two starts in 2001.

53: Saves for Francisco Rodriguez of the Angels, just four away from the record set by Bobby Thigpen in 1990. He's done it in 58 chances so far. 60 should be a reasonable target, although the Angels are banged up right now.

354: Wins for Greg Maddux after his win Monday, tying Clemens for eighth on the all-time list.

536: Home runs for Jim Thome. Would you believe he now has as many as Mickey Mantle? Thome will be 13th all-time.

549: Home runs for Alex Rodriguez. He passed Mike Schmidt on the all-time list on the replay-affirmed homer. A-Rod now has more homers than any non-outfielder or first baseman in big-league history.
