"We haven't gotten beyond the game of catch at this time. It hasn't been fluid or completely pain free," Reds manager Bryan Price said. "It's safe to say that Daniel will make that start."
Even if Latos had improved enough to pitch in the next series vs. the Pirates this coming weekend, the Reds are not going to take final starts away from Mike Leake, Alfredo Simon and Johnny Cueto.
"My goal was we knew Johnny was going to pitch Game 1 against Milwaukee [on Tuesday], and we felt like if we got to the point where Game 2 or 3 was when [Latos would] be ready, he could pitch then. That does not look like the case. We're just not moving along fast enough."
Latos finished his injury-shortened season with a 5-5 record and 5.25 ERA in 16 starts. He spent all last winter rehabilitating from October elbow surgery to remove bone chips. Just before Spring Training started, he tore meniscus cartilage in his left knee while throwing.
Another setback came when Latos strained the flexor mass tendon during a rehab assignment in the Minors. He did not return from the disabled list until June 14, but pitched well, for the most part, when he was healthy.
Latos will be third-year arbitration-eligible this offseason after earning $7.25 million in 2014.
