Adrian Beltre discussion heats up 

It’s still a lukewarm prospect at best, but the Giants-Adrian Beltre chatter will be relevant as long as San Francisco keeps getting subpar production at the hot corner (likely) and the Rangers stay low on the AL West totem pole (likelier).

I actually dropped some knowledge on this rumor before Grantland and SB Nation made it cool (h/t ESPN’s Jim Bowden for the heads up), postulating that the pricey third baseman would be worth watching if the Giants kept struggling to score runs and Texas was indeed selling at the deadline.

Beltre, known mostly for his power, actually boasts Hall-of-Fame worthy two-way play, making him an even more attractive option.

But the hold-ups to this deal happening—and they’re big ones—aren’t too different than the ones halting a potential trade for Troy Tulowitzki: 1) lack of tradeable pieces 2) unwillingness to pay a premium 3) swap penchant for injuries with advanced age—and we’ve arrived at the same conclusion.

Connecting the dots can be such a downer sometimes.

Still, while third base may no longer be a red flag for the Giants, upgrading the position for the long-term (no, not with Adam Duvall) isn’t out of the question.
