I've discussed the difficulty of finding bats, especially ones with a modicum of power, in other threads. And praised the approach of teams that have focused more on accumulating hitting rather than pitching.
It is worth noting that others seem to agree. John Hart, for example, offered a couple interesting quotes after the Olivera trade. These are all from the AJC.
“You look out onto the market and it’s just tough to find those bats,” Hart said. “We don’t want to give up our draft picks (to sign big-ticket free agents)."
“Look, we just don’t have the upper-level bats that are in the (minor league) system. We’re going to have to be creative in how we bring in some of these guys…."
Another GM was quoted as saying having a hitter to trade at this year's deadline was like having a pot of gold, and not so with pitchers.
Finally, I will note that the past few off-seasons I've tracked what FA pitchers get paid per projected WAR and what hitters get paid. Typically, pitchers have been paid more by this measure. But this switched dramatically last off-season. I don't think it will switch back anytime soon.
