Randy Johnson is a free agent and the Diamondbacks aren’t going to re-sign him. He supposedly could be had for a one-year deal and just $8 million. He’s still a very good pitcher and while he’s had his share of back injuries in recent years, he still threw 184 innings in 2008. He threw over 200 in 2004, 2005 and 2006 before missing most of 2007.
There’s a risk that the back could give out and he misses the entire season, but at $8 million I think it’s a risk worth taking. The Cubs just saved around $6-8 million by not re-signing Wood so they have the money.
Randy Johnson isn’t just mediocre at this late stage of his career, he’s still one of the better starting pitchers in baseball. Since returning to the NL, Johnson’s ERA has been around 3.90 over 250 innings. He was 14th in the NL in FIP. His expected FIP of 3.88 was 9th in the NL and better than Jake Peavy’s 3.92. Johnson is middle of the road ace.
The average tRA+ (just like ERA+ and OPS+) of a number one starter is 130. The averages for all slots are below.
AVERAGES. (based on 2007 and 2008 data)
#1 STARTERS: 130 tRA+
#2 STARTERS: 112 tRA+
#3 STARTERS: 100 tRA+
#4 STARTERS: 91 tRA+
#5 STARTERS: 76 tRA+
Randy Johnson’s tRA+ in 2008 was 130. He’s an average number 1 starter. Or was in 2008 anyway. He posted a tRA+ of 137 in 2007 and with the Yankees in 2005 and 2006 it was 120 and 121. If you’ve read the article I linked above about the average tRA+ for the 5 starting slots, you’ve seen than the barrier for a number 1 starter is 118. The last time Randy Johnson was below that was in 2003 at 109.
How does Randy Johnson’s last few years compare to some of the Cubs starters in 2008? Ryan Dempster’s tRA+ was 127. Carlos Zambrano was 113. Rich Harden was 146.
According to tRA, Randy Johnson would have been the 2nd best Cubs starter in 2008. If we use FIP, Johnson’s 3.73 FIP would have been just behind Ryan Dempster (3.46) and Rich Harden (3.10). Cole Hamels FIP was 3.70.
Johnson’s fastball still has some life. It was 90.8 mph and I’m guessing that was down because of the back injury (it was above 92 a year ago). His 3.91 ERA wasn’t helped out by the .316 BABIP he allowed. He still struck out 8.46 batters per 9 and Bill James projects he’ll strikeout over a batter per inning 2009. He walks around 2 per 9.
He still has plenty left and is one of the best pitchers in the game. Over his last 13 starts in 2008 he posted a 2.41 ERA. He struck out 78 in 86 innings while walking only 16. That’s more than a 5 to 1 k to walk ratio.
For only one year and $8 million you aren’t going to do better than Randy Johnson. It’s an extremely low risk and very high reward kind of deal.

If they dump Marquis then essentially you’d be replacing Marquis with Johnson and I’d take that everyday.
