Where does Ken Griffey Jr. rank among the great center fielders of all time?

30 Comments

Ken Griffey Jr. called it quits yesterday following a 22-season career in which he batted .284 with a .370 on-base percentage, .538 slugging percentage, 630 homers, 524 doubles, 2,781 hits, 184 steals, 1,312 walks, 1,662 runs, 1,836 RBIs, 13 trips to the All-Star game, 10 Gold Gloves, and one MVP.
Those numbers and accomplishments speak for themselves and make it clear that Griffey is an obvious Hall of Famer, but determining exactly where he ranks among the greatest center fielders in baseball history is a little more difficult.
Thankfully there are some good career-assessment methods to put his greatness in context, one of which is “Wins Above Replacement” or “WAR.” Available at Baseball-Reference.com, WAR represents “the number of wins the player added to the team above what a replacement-level player would add.” In other words, if instead of having Griffey for 22 seasons his teams were forced to use run-of-the-mill Triple-A players in his place, how many wins would it have cost?
Here’s how Griffey ranks in WAR among everyone who played center field at least two-thirds of the time:

                     WAR
Ty Cobb            159.4
Willie Mays        154.7
Tris Speaker       133.0
Mickey Mantle      120.2
Joe DiMaggio        83.6
KEN GRIFFEY JR.     78.4
Duke Snider         67.5
Jim Edmonds         67.1
Kenny Lofton        65.3
Andruw Jones        59.2



If you look only at what all the center fielders did through the age of 30, Griffey moves up from sixth to fourth, with Mickey Mantle in the top spot followed by Tris Speaker and Willie Mays. However, just 3.9 of his 78.4 WAR came after age 30, as Griffey ceased being a capable center fielder, struggled with injuries, and saw his OPS drop more than 100 points.
Jay Jaffe of Baseball Prospectus has developed a metric called “JAWS” that takes into account not only a player’s career-long performance like WAR, but also factors in how strong his peak seasons were. In other words, how good was someone in total and how good was someone at their best. Here’s how Griffey stacks up against other center fielders in JAWS:

                    JAWS
Willie Mays        118.2
Ty Cobb            104.7
Tris Speaker        91.8
Mickey Mantle       89.4
Joe DiMaggio        73.6
KEN GRIFFEY JR.     65.8
Jim Edmonds         61.7
Billy Hamilton      56.4
Andruw Jones        54.4
Richie Ashburn      54.3



WAR and JAWS both produce the same top six, in the same order. Also, it’s worth noting that the average Hall of Fame center fielder accumulated a JAWS of 56.1, so not surprisingly Griffey clears that hurdle with ease. Jaffe’s column on Griffey also gets into plenty of other interesting aspects of his standing among center fielders, so it’s definitely worth checking out.
At the end of the day it’s pretty clear that Griffey is among the top six center fielders in baseball history, along with Willie Mays, Ty Cobb, Mickey Mantle, Joe DiMaggio, and Tris Speaker. Exactly how those six should be ordered makes for a pretty good debate, but that’s some amazing company however you slice it. Hopefully once the Jim Joyce-related stuff dies down a bit, it’ll be easier for people to focus on how great Griffey was.

Matt Wieters is close to signing with the Washington Nationals

Jon Heyman reports that the Nationals are closing in on a deal with catcher Matt Wieters. Joel Sherman of the New York Post reports that it’s a two-year deal. UPDATE: Ken Rosenthal reports that the deal is for two years, at $21 million. There is an opt-out for him after year one. He will get $10 million in 2017 and, if he returns in 2018, he’ll get $11 million.

Wieters was not expected to go this long without signing, but his market, which many thought would be robust, never materialized. The Nats had been rumored to be interested for months, but they were apparently waiting to swoop in late and get what one presumes will be a bargain.

Wieters, 30, finished last season hitting .243/.302/.409 with 17 home runs and 66 RBI in 464 plate appearances. The Nationals currently have Derek Norris and Jose Lobaton, so who falls where in the catcher fight in Washington is unclear, but one presumes that Wieters getting a two-year deal puts him at the top of the depth chart.

Sergio Romo experienced some difficulty in the past couple of years

Ken Rosenthal has an interesting story up about Sergio Romo as he begins spring training with his new team, the Los Angeles Dodgers.

There is some fun stuff about his family, all Dodgers fans from southern California, but the more notable stuff is about Romo himself, who has dealt with a lot more than has been reported over the past couple of seasons. The loss of three of his four grandparents is a big one, as it has thrust the mantle of head of the family on Romo in ways that he was not fully prepared for. There are also allusions to personal and psychological problems Romo has experienced — there is a vague suggestion of alcohol or maybe just late nights out and perhaps depression, but he is not specific about it — which he worked on with the help of friends and teammates on the Giants and which he now has overcome.

There’s always more going on the lives of baseball players than we as fans know.
