All spring long, it appeared that Eric Stults and Wandy Rodriguez would likely begin the season as Atlanta’s 4th and 5th starters. However, the Braves recently expressed that they were not comfortable with two left-handers at the end of their rotation. Their response: trading for RHP Trevor Cahill from the Diamondbacks. Cahill broke out in 2010, when he was voted an All-Star in his second season and even received a handful of Cy Young Award Votes. However, things all went downhill from there. While Cahill has still compiled a couple of decent seasons since then, he never reached his potential and struggled to a 5.61 ERA and a 3-12 record last season. So where is the upside in this deal? He did post a 3.60 ERA this spring and the Braves liked what they saw out of his spring outings. He’s also a righty, unlike Eric Stults and Wandy Rodriguez, who was released this morning. This will be a great project for Roger McDowell to see if he can revive this kid’s career. The Braves are only on the hook for $5.5 million of his salary, as Arizona will pay the remaining $6.5 million. Atlanta sent minor leaguer Josh Elander to Arizona. Cahilll will hit free agency this coming season unless he pitches well enough for Atlanta to use their club options that they have over the next two seasons, which are in excess of $13 million annually. While a risk, Cahill will undoubtedly be an interesting guy to keep an eye on this season.
