Jake Arrieta deserves the benefit of the doubt, and I take him at his word when he said after the Orioles' 8-3 victory over the Pittsburgh Pirates last night that he "just had one of those nights" when he didn't feel too good physically. The right-hander had a 7-0 lead by the time he took the mound for the second inning, yet he proceeded as if every one of his pitches could win or lose the game. Arrieta is a bulldog. He wants the ball, he keeps himself in great shape and, above all, he has great stuff. His biggest issue is that he pitches way too tentatively at times. If you have the lead he had last night, you have to figure out a way to go at least seven innings. That's not going to happen when you are going to three-ball counts with every batter, including one of the Pirates' relief pitchers. It's something I believe Arrieta will learn and get better at, and he'll have to. He has made 16 starts and has pitched more than six innings in only three of them. But let's be clear: The Orioles have way too many other issues before they have to start worrying about Arrieta, who has made major strides in his first full big league season.
