I used baseball reference play index to find all 36 year old starters who started at least 28 games. I found 28 pitchers. Those 28 pitchers averaged 3.2 WAR with 21 pitchers over 2. (I used BR WAR as it is tied to their play index).

By age 39, only 25% of the pitchers are at that level. There were 8 pitchers who aged well and account for most of the age 38 and 39 stats. Those pitchers were Roger Clemens, Tom Glavine, Randy Johnson, Greg Maddux, Jamie Moyer, Mike Mussina, Andy Pettitte and David Wells. If the Twins put Bronson Arroyo in that class, they should absolutely give him a multiyear contract. If not, anything beyond a one year deal would be a foolish investment to appease the fans in hopes of generating interest and ticket sales. Edit: Baseball reference has a similar pitchers through age 36 on Arroyo's page. While none of the 8 mentioned above landed on his list, several were on the original list of 28. John Burkett(#1) and Tim Belcher(#3) should be of particular interest to any team considering signing Bronson. They both signed 2 year deals following a solid 36 year old season. Burkett had two seasons worthy of a #5 starter and retired not making it to 39. Belcher was awful in his 33 starts for Anaheim posting ERAs above 6 at age 37 and 38 before retiring.
