Teheran, who was widely regarded as one of the top five prospects in the majors last year at this time and in 2011, slipped a bit after struggling to a 7-9 record, a 5.08 ERA, a 1.44 WHIP and a .289 opponent’s batting average at Triple-A Gwinnett. In 26 starts and 131 innings, he allowed 146 hits.
Those numbers were significantly less impressive compared to 2011, when Teheran was 15-3 with a 2.55 ERA and a 1.18 WHIP while permitting just 123 hits in 144.2 innings. In seven games, including four starts, with the Braves over the last two seasons, he owns a 5.19 ERA and a 1.35 WHIP. His ceiling remains high, though, because of three plus pitches (fast ball, curve ball, change-up).
Teheran will be 22 on January 27, so he is still young and is gaining strength and Major League experience. He has a chance to eventually emerge as the ace of a deep and talented Braves rotation. As for 2013, Teheran will battle for a rotation spot in spring training.
The 18-year-old Sims was Atlanta’s first round pick (21st overall) in 2012. Out of Snellville, Ga., the right-hander has an above-average fast ball and curve ball, and his change-up is still in development.
Because he signed early, Sims gained experience in the Gulf Coast League (1.29 ERA and 0.43 WHIP with a .091 opponent’s batting average in three starts) and the Appalachian League (4.33 ERA and 1.41 WHIP with a .243 opponent’s batting average).
A first round pick (28th overall) out of Florida State University in 2011, the 22-year-old Gilmartin is not flashy, yet the left-hander keeps hitters off-balance with a plus change-up and has strong command.
He drew attention with a 3.54 ERA and a 1.15 WHIP while holding hitters to a .245 average in 20 starts and 119.1 innings at Double-A Mississippi in 2012. Gilmartin received a promotion to Triple-A Gwinnett and posted a 4.78 ERA and a 1.43 WHIP in seven starts.
With further development in 2013, he could make his Major League debut if an injury arises in the Braves rotation.
