Pirates to skip Happ for series vs. Cardinals

PITTSBURGH -- Manager Clint Hurdle announced the Pirates' rotation for next week's series against the Cardinals, a trio of starters that does not include left-hander J.A. Happ.

The Pirates are going to skip Happ's second scheduled start since he joined the team. Instead, the Bucs plan to send out left-hander Jeff Locke on Tuesday, right-hander Gerrit Cole on Wednesday and lefty Francisco Liriano on Thursday in St. Louis.

Acquired last week from the Mariners in exchange for Triple-A right-hander Adrian Sampson, Happ allowed four runs on eight hits and two walks over 4 1/3 innings in his Pirates debut Tuesday against the Cubs.

Happ was effective in his first 11 starts this season, but has struggled since then. Over his last 11 outings, the veteran left-hander is 1-6 with a 6.80 ERA, and opposing hitters have put together a collective .312/.377/.492 batting line during that stretch.

With a long layoff between starts, Happ was available out of the Pirates' bullpen on Friday night against the Dodgers, Hurdle said. In the meantime, he will work with pitching coach Ray Searage in an attempt to return to his early season form.

"They'll do some side work from time to time. I think Ray and him have already touched upon what's important, what we need to do to help him be the consistent pitcher that he showed the first half," Hurdle said. "It's really not about fixing him. I think it's more about fine-tuning some things."

Around the horn
• Reliever Deolis Guerra is back with the Pirates. The Indians on Friday rescinded their waiver claim of Guerra, who was returned to the Pirates and placed on the 15-day disabled list with left knee inflammation.

According to the Indians, the claim was retracted due to a previous injury in Guerra's left knee. To make room for Guerra on their 40-man roster, the Pirates designated right-hander Wilfredo Boscan for assignment.

• Reliever Rob Scahill (forearm) began his Minor League rehab assignment on Thursday, throwing two scoreless innings with one strikeout for the Gulf Coast League Pirates.

• Right-hander Vance Worley was sent outright to Triple-A Indianapolis on Friday, according to the International League transactions page. The Pirates designated Worley for assignment on July 30 when they activated right-hander Joe Blanton.

Worley, who was bumped to the bullpen earlier this season, was 4-5 with a 3.78 ERA over 20 appearances, including eight starts. Keeping him in the organization bolsters the Bucs' rotation depth, which has been depleted by injuries this year.

• Top prospect Tyler Glasnow made his second start for Indianapolis on Thursday. The right-hander allowed four runs (one earned) on three hits, six walks and a hit batter while striking out six in 4 2/3 innings. He also allowed six stolen bases.
