Sports – Re-signing Mike Sweeney

While traveling for business last week, I missed this little item in the Kansas City Star: “Royals could re-sign Sweeney if Butler proves capable of playing first.”

The reasoning goes something like this: The Royals have very little power in their lineup. Signing a free agent with power will be expensive. Mike Sweeney has power and is already here.

I am curious about two specific aspects of this story. 1.) Does Mike Sweeney still have power? And 2.) How much should the Royals pay him for this?

I am leaving out the question of Billy Butler’s ability to man first base, because I think that he can certainly play it as well as Ken Harvey and… er… well, Mike Sweeney did.

Does Mike Sweeney still have power?
Joe Sheehan made a comment in a chat at Baseball Prospectus the other day that I found interesting: “[Y]ou should consider extra-base hits together as a group (or in a rate like XBH/H, XBH/AB, ISO) as opposed to isolating one category of hits. Guys can see doubles turn into homers one year and back the next for no real reason.”

Let’s see how the original $11 million Royal has done at hitting for power consistently over his career.

Year  AB   XBH  XBH  ISO
           /H   /AB  
1995    4   0%   0%  000
1996  165  30%   8%  133
1997  240  26%   6%  121
1998  282  36%   9%  149
1999  575  37%  12%  198
2000  618  29%  10%  190
2001  559  44%  13%  238
2002  471  35%  12%  223
2003  392  30%   9%  174
2004  411  38%  11%  217
2005  470  43%  13%  217
2006  217  41%  11%  180
2007  204  36%   9%  162
CAREER     36%  11%  194

Not bad. Sweeney has lost a bit of isolated power the last few years, but his extra base hit percentages are still in line with his career numbers.

Before his latest trip to the disabled list, Sweeney had 7 home runs in 204 at bats. That put him on pace for 15 round trippers if he could have managed to stay healthy enough for 450 at bats. Don’t look now, but that would put him one behind John Buck for the team lead.

I’ll go out on a limb and say that the power is still there for Mike. A healthy Mike Sweeney could put 25 dingers on the board in a season, and while that won’t get him into any Barry Bonds debates, it would certainly help a team as anemic as this current Royals squad has been with the long ball.

Of course, the phrase “a healthy Mike Sweeney” is akin to “I want a pony” for most Royals fans. But, the fact is Sweeney is playing rehab ball in the minors right now. He will be able to play baseball next season and somebody will sign him.

How much should the Royals pay him for this?
Using some quick and dirty math along with the Play Index over at Baseball Reference, I cobbled together the following list of players I felt were having comparable seasons to Sweeney.

It’s good to know the Royals aren’t the only team overpaying for below-average production and disabled list time.

Taking a quick average of Sweeney’s last three years, how does he stack up with your average older, oft-injured player?

And some of this year’s numbers just for fun…

Player  Age OPS+
Sweeney 33  82
Gload   31  99
Brown   32  65
Costa   25  77*

*Costa’s OPS+ is from last season, when he spent significant time at the big league level.

Gload and Costa are relatively cheap. Emil Brown is getting paid $3,450,000 for his contributions this year. The Oakland Athletics have paid Frank Thomas and Mike Piazza $500,000 and $8,500,000 respectively over the last two years to man the designated hitter post with varying levels of return.

It’s funny to say it, but if the Royals can get Mike Sweeney’s average production from the last three years for Emil Brown money, I say they make that deal.
