The Red Sox have acquired Jake Peavy in a three team trade. The Sox sent Jose Iglesias to Detroit, and a trio of spellcheck challenging minor leaguers (infielder Cleulius Rondon and pitchers Francelis Montas and Jeffery Wendelken) to the White Sox. The Red Sox also acquired reliever Brayan Villareal.
Peavy is one of those guys who look like great players around the trade deadline. In actuality he's just good. He's 8-4 with a 4.28 ERA. He's never really succeeded in the American League. Apart from last year's 3.37 ERA. I'd completely forgotten that he won the NL Cy Young in 2007. He was once a great pitcher.
He, however, is still a good pitcher, and the Red Sox needed a good pitcher. Clay Buchholz's status remains a mystery. Brandon Workman has pitched well but it's risky to rely on a 24-year old to keep your rotation stable. Peavy fits snugly in the middle of that rotation, behind Lester and Lackey, ahead of Dempster and Doubront.
Losing Jose Iglesias hurts. He was hitting .330, and was getting on base (.376 OBP). He provided depth and options on the left side of the infield. Then again, he was hitting .205 in July, with only 1 extra-base hit all month. Even when he had been hitting well, he hadn't been hitting for power.
You have to make this move. Pitching is so much more valuable than an infielder.
One reason the Red Sox could fail during this playoff push is lack of pitching. They're not going to fail because they lack a light-hitting left-infielder. Peavy solidified their rotation. Getting 11 starts from a pitcher like Jake Peavy is worth Jose Iglesias. Peavy is also under contract for next season.
Peavy doesn't push them over the top, but he fills holes that might have sunk the ship.
