Yeah, for the Orioles, four games IS a streak. Here are some random thoughts that don't deserve full posts of their own...
With all the veteran power bats the Orioles signed over the winter, it has been the 5'9" Brian Roberts who has been fueling the offense during Baltimore's 4-0 start.
As an observation, the Orioles are better with the additions of Vladimir Guerrero and Derrek Lee so far. That might seem like an early judgement, but the other hitters in the lineup are benefiting from the veteran presence. Guerrero's only batting .125 with no RBIs. Lee is batting just .214 with 0 RBIs. Brian Roberts, at the top of the order, is batting .294, however, with eight RBIs and two home runs. Nick Markakis, batting second, went 3 for 3 in the opener and is batting a scorching .429 with six hits. Pitchers are fearing what's coming after Roberts and Markakis instead of fearing the formidable duo at the top of the order.
First, I would direct Mr. Palmer here for proof that lineup protection does not exist or at the very least is incredibly overstated.
Second, even if I were to accept the concept of lineup protection, there are some logic fails with this argument. The guys hitting .125 and .214 are providing so much scary offense that Roberts and Markakis are seeing more good pitches? And how come Lee isn't benefiting from Vlad hitting behind him in the lineup? Shouldn't he be seeing better pitches too? If so, why is he hitting .214? And Matt Wieters has hit well so far. Is he benefiting from Adam Jones' .125 batting average too? And shouldn't Roberts and Markakis be seeing more fastballs? Because they're not. Roberts is seeing fastballs at about the same rate as he ever has. Markakis is actually seeing far less. There are a lot of holes in that story.
The top of the order is succeeding in spite of the "veteran presence" through four games, not because of it. Unless you believe in wizardry, voodoo and The Force.
