Jonny Gomes: With the recent acquisition of Chris Young by the A's, Billy Beane all but said that they will not pursue Gomes' services for next year. Gomes provides the compliment to Juan Francisco in LF if the Braves go the route of letting him start against RHP. Gomes has a career .284 AVG and .894 OPS against LHP. He would probably only command 3yr/7-8mil, so this would be a very cost efficient move for the Braves while getting consistent production from Martin Prado and a platoon partner for Francisco.
Craig Gentry: I've talked up Craig Gentry before, and the fact that he still seems under the radar means that Texas has made it known he's not available or he's not being considered by others. Gentry in a limited role with the Rangers, has a .775 OPS in his career along with providing excellent defense in CF. Gentry is also still in his arbitration years, and would be much cheaper than bidding wars for the numerous CF on the free agent market. He's 28 and right-handed, but Gentry is good way for the "Budget" Braves to solve CF questions.
Bryan LaHair: I get it, he's old, he has little defensive value, he strikes out alot,and he's a AAAA player. LaHair though does do somethings well, mainly hit RHP, and pinch hit. The Braves are in the market for a LH bench bat and LaHair fits that mold at a paltry 580K and not even arbitration eligible. He offers the same defense as Eric Hinkse and is a career .289 AVG, .835 OPS against RHP. He also has a .914 OPS as a PH in his career. LaHair has no place in the Cubs future plans and as a bench bat would be worth a flyer by the Braves.
John Jaso: A player with an up and down career who has only played catcher, Jaso has also been a superb RHP masher. The drawbacks are Jaso has provided enough value as cheap reliable option for Mariners that he will command at least one decent prospect, which is probably too much for a guy who would be a bench bat for the Braves. It is unknown if Jaso could play a different position other than catcher, perhaps as a corner IF/OF Jaso could be the best LH bench bat option, but his current value and postitioning make the trade waters murky. Jaso's line against RHP - .270 AVG, .368 OBP, .789 OPS, and 125 wRC+. Sidenote: Jaso could also provide a bridge to Bethancourt if the Braves deem Brian McCann not the long term answer at catcher.
Andy Dirks: Corner OF for the Tigers who possesses less of a platoon split, but definitely a solid option for LH bench bat. Dirks has batted .294 AVG, .795 OPS, and 115 wRC+ against RHP. His 117 wRC+ against LHP also suggests he would not be a liability if thrust into an everyday role due to injury. Dirks is also a career .353 AVG hitter as a PH. Dirks isn't arb-eligilble until 2015, and seems to be poised for an increased role next season with Tigers. However given the Tigers' proclivity for spending in the offseason, if the acquire another outfielder amidst the rise of Avisail Garcia, Dirks could very well be available on the market. Another cheap role player who provides good value.
Obviously most of these players address the Braves bench and players for platoon. Each however is a cheaper and statistically equivalent option to what the Braves could acquire elsewhere.
