Julio Teheran is one day older today than Josh Beckett was in November 2005 when the Red Sox traded top prospects Hanley Ramirez and Anibal Sanchez (and two others) to the Marlins for Beckett, Guillermo Mota and the then-underwater contract of Mike Lowell.
Beckett came with two years of team control while Teheran remains under team control for three-and-a-half years at a bargain rate with a team option for an additional year.
Here are the stat lines for Beckett at the time of the trade and for Teheran today (with all stats compiled while pitching for a National League East team):
JB 106 G, 103 GS, 609.0 IP, 3.46 ERA, 1.24 WHIP, 118 ERA+, 10.7 bWAR, 13.7 fWAR
JT 120 G, 117 GS, 746.0 IP, 3.33 ERA, 1.15 WHIP, 113 ERA+, 12.0 bWAR, 8.5 fWAR
In 2006 Baseball America ranked Ramirez and Sanchez No. 30 and No. 40 on its Top 100 prospect list after ranking Ramirez No. 10 the previous year.
Given the comps, especially the years of team control, the Braves would not be unreasonable in demanding a top Red Sox prospect or two in exchange for Teheran.
