The team that’s scored the most runs in baseball this year just made their offense better by trading Jose Reyes and minor leaguers to the Rockies for Troy Tulowitzki. Ken Rosenthal broke the news, but the full details are not yet available.

Because of the fit, there will be the inevitable questions about further moves — Toronto had been rumored in on most pitchers, and scores more than a half run more than the second-best offense in baseball, and Reyes now seems a poor fit on a rebuilding squad in Colorado — but a second move isn’t required to like this for the Blue Jays.

The game is about getting better, on the run scoring or run prevention side. And if the Jays score six runs a game, they should win more than if they score five and a half. Given that the difference between the yearly outlay for Reyes actually trumps Tulowitzki’s, this deal is even budget neutral. Maybe that’s why Dave Cameron thought it up a while back when he dreamt up some Tulowitzki trades:

Toronto Blue Jays
The Jays don’t really need another right-handed slugger, and with Jose Reyes on the books and Devon Travis playing well at second base, they probably don’t need another middle infielder either. But they do have the kind of young arms that Colorado would likely be interested in. Of the Rockies took Reyes back with some of those pitching prospects, maybe there’s a deal to be struck here, as the monetary differences wouldn’t be all that large anymore. In reality, the Blue Jays path of least resistance is to find another starting pitcher or two to upgrade their own rotation, rather than trading young arms for another big bat, but it’s not impossible to see Alex Anthopolous getting involved if he sees this as the best addition he can make to a team that needs a short-term boost to help an aging core make a push to the postseason.

The rest of the pieces are starting to come through — LaTroy Hawkins is going to Toronto! — and they may change the analysis of the deal going forward. Too many young pitchers going to the Rockies, and you hurt your chances of acquiring other pitchers to help your win-now team on the other side of the ledger. JP Morosi had the first news of the prospects in the deal when he said 22-year-old lefty Daniel Norris was not in the trade, and that has to be a good sign for Jays fans. He was the top prospect in Toronto according to Kiley McDaniel earlier this year.

But the thirty-year-old Tulowitzki is no creation of his home park. His away offense has been 19% better than league average over his career, and that would be the third-best offensive shortstop in baseball this year. Add in a top-five glove at his position since he entered the league, and there’s no way the Blue Jays didn’t get better tonight.

The Rockies? It might depend on what they do going forward with their new 32-year-old shortstop.
