Pirates GM Ben Cherington said Sunday that Jones (lat) will make at least one more rehab start before returning from the 15-day injured list, Noah Hiles of the Pittsburgh Post-Gazette reports.
The right-hander has struggled in his two rehab outings for Triple-A Indianapolis with six earned runs allowed across six innings. Jones encouragingly built up his workload to 67 pitching during his last appearance, but the Pirates might want to see him regain some effectiveness before re-inserting him into the big-league rotation.
