PITTSBURGH — On the diamond, Juan Nicasio demonstrated part of the problem with Pittsburgh’s rotation, allowing a pair of quick extra-base hits Sunday.

Off the field, general manager Neal Huntington talked about a potential solution to the Pirates’ pitching problem: the progress of top-rated prospect Jameson Taillon in Triple-A.

The game between the Colorado Rockies and Pirates was postponed because of rain after one inning. The Rockies led 1-0 on Nolan Arenado’s RBI triple when the game was called after a wait of 3 hours, 37 minutes.

The teams will play the makeup on Monday.

Taillon was the second overall pick in the 2010 draft and was on a meteoric path through the Pirates’ minor league system before Tommy John surgery and a hernia injury derailed his 2014 and 2015 seasons.

Back on the mound, the 24-year-old Taillon is turning heads, posting a 1.82 ERA with 51 strikeouts and five walks in his first eight starts.

“This young man took advantage of those two years,” Huntington said. “He bristles when someone mentions that he lost those two years. He didn’t lose two years; he just wasn’t pitching for a year and a half.”

With Taillon making big strides, the continued struggles of Pirates’ starters in the majors has become more of a hot-button topic. Gerrit Cole is the team’s only starter with an ERA below 4.00.

Adding a Taillon to the rotation could help the team elsewhere, too. Nicasio, who was originally slated for the a relief role before winning a starting job in spring training, could return to the bullpen, which currently sits 13th in the National League with a 4.33 ERA.

Still, Huntington isn’t rushing his top prospect.

“We’d love to give our guys more experience in Triple-A than we have in the past,” he said. “I think the results — when we’re able to give guys a significant amount of experience in Triple-A — show. They make an easier transition.”
