SAN DIEGO -- Multiple industry sources have confirmed that the Red Sox have an agreement to acquire left-handed starter Wade Miley from the Diamondbacks in exchange for right-handers Rubby De La Rosa, Allen Webster, with a minor leaguer also believed to be heading to Arizona. News of the trade agreement was first reported by Ken Rosenthal and Jon Morosi of Fox Sports (via twitter). The deal is not yet official, but is expected to be finalized in the coming days. One Arizona official insisted, "Nothing if official. Nothing has been finalized." Still, the issue appears to be little more than procedural. Miley fills a pair of needs for the Red Sox as a pitcher who can shoulder a reliable innings load (he's logged three straight years of 198 or more innings) and he's left-handed, giving the Sox some diversity in their rotation. As written in this blog post earlier today: In parts of four seasons, Miley, a 2008 first-rounder, is 38-35 with a 3.79 ERA. He'€™s thrown at least 194 innings in each of the last three seasons, performing at a level described by one evaluator as a solid No. 4. He'€™s struck out 7.0 per nine innings in his career, including a career-high 8.4 per nine innings in 2014, though after posting ERAs of 3.33 and 3.54 in 2012 and 2013, Miley had a 4.34 ERA last season. That said, his numbers were made worse by a putrid Diamondbacks defense, and he'€™s also spent his career in one of the more difficult home pitching environments in the game. While he is not being viewed by the Sox as a potential top-of-the-rotation replacement for Jon Lester, his career track record suggests a potentially stabilizing rotation presence. Miley is eligible for salary arbitration for the first time this offseason. He remains under team control for three years before he'€™ll be eligible for free agency following the 2017 season. The success of Brandon McCarthy after he was traded from the Diamondbacks to the Yankees last year gives the Red Sox some reason for optimism regarding the potential for Miley to adapt well to the AL East. McCarthy was 3-10 with a 5.01 ERA in 18 starts for Arizona, though with some indicators (such as a career-high strikeout rate) that suggested he was outperforming those numbers by a considerable distance. With New York, he was 7-5 with a 2.89 ERA in 14 starts, ratifying that outlook. Miley, 28, was considered a positive clubhouse presence with the Diamondbacks. In Webster and De La Rosa, the Red Sox would part ways with two pitchers acquired in the August 2012 deal with the Dodgers who possess electric stuff that hadn't translated to consistent results. Webster, 24, was 5-3 with a 5.03 ERA in 11 starts in the big leagues last year. De La Rosa was 4-3 with a 4.43 ERA in 19 big league games (18 starts) in 2014. Questions loom about whether the long-term future of both is in the rotation or bullpen. Both have considerable upside (potentially even as starters) but ill-defined floors. De La Rosa is out of options; Webster has one minor league option left. The identity of the third piece believed to be going to the Diamondbacks remains unknown.
