It turned out that the Yankees did not trade a future American League Rookie of the Year Award winner to get Curtis Granderson from the Tigers 11 months ago.

Austin Jackson, a highly-touted prospect in the Yankees’ system, went to Detroit along with relief pitcher Phil Coke in the three-team trade also involving the Diamondbacks Dec. 8, 2009 that brought Granderson to the Bronx and included sending pitcher Ian Kennedy to Arizona.

When Jackson got off to a smoking start for the Tigers as their center fielder and leadoff hitter, Rookie of the Year talk surrounded him for much of the first half. Jackson tailed off somewhat in the second half, although he still had a fine year. It just was not as good as that of Rangers closer Neftali Feliz, who set a rookie record with 40 saves and was the choice of the Baseball Writers’ Association of America for the Jackie Robinson Award that was announced Monday.

Felix, 22, was listed first on 20 of the 28 ballots submitted by two writers in each league city, second on seven and third on one to amass 122 points, based on the 5-3-1 tabulation system. Feliz’s saves total broke the previous rookie mark of 37 by 2000 winner Kazuhiro Sasaki of the Mariners.

Feliz, who had a 4-3 record with a 2.73 ERA in 70 relief appearances, is the first Dominican pitcher to win the award and the third winner from the Dominican Republic overall, joining Alfredo Griffin and Angel Berroa. Dominican-born winners in the National League were Raul Mondesi, Rafael Furcal, Albert Pujols and Hanley Ramirez.

A closer has won the AL award three times in the past six years. Oakland’s Andrew Bailey won in 2009 and Huston Street in 2005. Feliz is the fifth closer honored. The first was the Orioles’ Gregg Olson in 1989. Yankees pitcher Dave Righetti, now the Giants’ pitching coach, was a starter when he won the award in 1981. Feliz is the second Rangers player to win the award. The other was first baseman Mike Hargrove in 1974.

Jackson, who received the other eight first-place votes and was the runner-up in the balloting with 98 points, led all AL rookies in runs (103), hits (151), doubles (34), triples (10), extra-base hits (48), stolen bases (27) and total bases (247). Jackson batted .293, stole 27 bases and scored 103 runs, but he struck out 170 times, a very high total for a player who hit only four home runs.

In the National League, Giants catcher Buster Posey beat out Braves right fielder Jason Heyward for the award. Posey, 23, was named first on 20 of the 32 ballots cast by two writers in each league city, second on nine and third on two to finish with 129 points. Posey hit .305 with 18 home runs and 67 RBI and handled a pitching staff that helped the Giants win the NL West title. His 21-game hitting streak from July 4-28 was the longest of the season by a rookie in either league.

Heyward (.273, 18 HR, 72 RBI) received nine first-place votes and was the runner-up with 107 points. Cardinals pitcher Jaime Garcia (13-8, 2.70 ERA) got one first-place vote and placed third with 24 points. The other two first-place votes went to Marlins first baseman Gaby Sanchez (.273, 19 HR, 85 RBI), who finished fourth with 18 points.

Posey was the sixth NL catcher honored, joining Johnny Bench, Earl Williams, Benito Santiago, Mike Piazza and Geovanny Soto. Catchers who won the award in the AL were Thurman Munson, Carlton Fisk and Sandy Alomar Jr. Other former Giants winners were Willie Mays, Orlando Cepeda, Willie McCovey, Gary Matthews and John Montefusco.

The victories by Feliz and Posey marked the third time since the award’s inception in 1947 that the winners were opponents in the World Series. The other years were 1981 when Righetti and the Dodgers’ Fernando Valenzuela started Game 3 at Dodger Stadium and 1951 when Mays and Yankees infielder Gil McDougald played in all six games of the Series.

It should have happened in 2003 with the Yankees’ Hideki Matsui and the Marlins’ Dontrelle Willis, but Matsui lost out to Berroa in a disputed election.
