It's time for the White Sox to trade Matt Thornton

Let's get right to the point of today's blog entry: There is no way Matt Thornton should be back with the White Sox in 2014.

Thornton is already overpaid this season. He's making $5.5 million. The White Sox hold a $6 million option on him for next year with a $1 million buyout. 

It would be insanity to pick up that option.

Thornton is being paid like a closer, but at this stage of his career, he's nothing more than a situational left-handed reliever. Just check out his lefty-righty slash line for this year:

vs. left-handers: .176/.236/.629
vs. right-handers: .333/.429/.866

Thornton looks like a pitcher who no longer trusts his stuff against right-handed batters. Case in point, Monday night's game against the Cubs. Thornton entered the game in the eighth inning of a 2-2 tie. He retired the left-handed batting Anthony Rizzo, then started picking at the corners of the plate against a pair of right-handed hitters.

It's difficult to walk the free-swinging Alfonso Soriano, but Thornton managed to do it on four pitches. He then fell behind 3-and-1 to switch-batting Dioner Navarro before giving up a single. Then, the left-handed Luis "Boom Boom Valbuena, who inexplicably owns the Sox, punked Thornton for a two-run double that gave the Cubs a 4-2 lead. That ended Thornton's night, and he took the loss as the North Siders went on to an 8-2 victory.

Thornton is 36 years old, and he's been in steady decline over the last four years. His numbers reflect that. Take a look at the statistics below. In particular, pay attention to the rising ERA and declining strikeout rate.

ERA
2010: 2.67
2011: 3.32
2012: 3.46
2013: 4.00

Ks per 9 IP
2010: 12.0
2011: 9.5
2012: 7.3
2013: 6.7

WHIP
2010: 1.005
2011: 1.358
2012: 1.231
2013: 1.296

Hits per 9 IP
2010: 6.1
2011: 9.1
2012: 8.7
2013: 8.3

HR per 9 IP
2010: 0.4
2011: 0.5
2012: 0.6
2013: 1.3

You can see the problem. Thornton doesn't miss as many bats these days. He gives up more hits and home runs than he did in the past. His ERA climbs each year as a result. It's nothing to be ashamed about. It's just reality for an aging pitcher who has made 60 or more appearances for 7 seven straight seasons. Soon, it will become 8 straight seasons.

There's no reason for the White Sox to waste $6 million on this declining pitcher for next season. Thornton is still useful as a situational left-hander, but you can find guys to fill that particular role for much less money.

There are rumors the Boston Red Sox are interested in Thornton's services for the rest of this year. If I'm White Sox GM Rick Hahn, I'm pulling the trigger on that deal.

Thornton's subtraction from the Sox roster will not hurt the team now or in the future. Thornton has done a nice job for the Sox through the years, but his best days are past and it is time for a change -- for both the player and the team.
