frankie rodriguez has been excellent this year. in 23 innings, he's allowed all of two runs (though there could be inherited runners he's allowed to score). per fangraphs, he has been worth 0.6 wins above replacement. jose reyes has also been excellent this year. in fact, according to fangraphs, he's our best player, and is worth 2.5 wins above replacement. prorating these performances over an entire season, and assuming that these performance levels are maintained throughout the season, we have frankie at 2.0 wins above replacement and jose at 8.4 wins above replacement. so, in order for trading frankie to keep jose to work our poorly for the mets, presuming the mets are able to keep only one, the mets would have to replace him with a reliever or group of relievers who are collectively worth -1.9 wins per 48 games, or -6.4 wins over the course of an entire season. alternatively, the only way that trading jose reyes makes the mets a better team this year is if they replace him with a 6.4 win shortstop. by the way. jose reyes is the best shortstop in the majors this year with his 2.5 WAR, leading alexei ramirez and asrubal cabrera at 2.0 WAR. last year, the top shortstop was troy tulowitzki, at 6.6 WAR. yes, the gap between jose playing like he is for a full year and frankie pitching the way he is for a full year, is a smidge less than troy tulowitzki. if it comes down to choosing between the two players, is it even a choice? i mean, damn. last year, about 100 pitchers were worth at least 2 WAR, including kyle davies, paul maholm, and barry zito, and 144 batters, including jeff keppinger, jorge posada, and derrek lee. thus far this season, torii hunter, chipper jones and aaron rowand are all 0.6 WAR players. thus far this season, jon niese and jeremy guthrie are 0.6 WAR pitchers. that is how much frankie rodriguez is worth. i think we can get much more in return than a chipper jones '11, or a barry zito '10. i don't think we're trading reyes for a '10 tulo.
