The Pirates will look to settle the score with the Orioles in a two-game series at PNC Park starting Tuesday. Baltimore swept a doubleheader between the two teams earlier this month.
Francisco Liriano will start for the Pirates. Although he's still looking for his first win of the season and has five consecutive no-decisions heading into Tuesday, the Pirates have won in each of those five outings.
Liriano is 0-3 with a 4.25 ERA over nine starts so far, but Pittsburgh manager Clint Hurdle says he expects great things from the 6-foot-2 lefty.
"I expect the best is yet to come for Frank; that's just what I believe," Hurdle said. "It's the time of the year for him where he normally makes his move. The swing-and-miss, all the pitches were there with the command. The fastball command sets it all."
He pitched six innings and gave up four hits and an earned run while striking out six in his last start against the Brewers.
Liriano is 2-3 with a 4.21 ERA in seven career starts against Baltimore, his last coming as a member of the White Sox at Camden Yards in 2012. He's gone 12-6 with a 3.28 ERA in 24 career Interleague games (23 starts), and was 3-1 with a 2.19 ERA in four starts against the American League while pitching for the Pirates last season.
The Orioles will counter with Miguel Gonzalez. He's coming off a strong start, going seven innings and giving up two runs against the Astros on May 10. On Wednesday, he allowed one earned run in two innings while pitching in relief against the Tigers.
Gonzalez's 35 strikeouts rank third on the Orioles' pitching staff. He has never faced Pittsburgh, but owns a 3.46 ERA (13 IP, 5 ER) in two career Interleague starts. Gonzalez is 0-2 with a 6.86 ERA in four road starts this season.
After going on a five-game winning streak in the middle of the month, the Orioles have slipped into a funk, losing six of their last eight games.
Pirates: Cumpton called up for doubleheader
On Sunday, the Pirates called up Brandon Cumpton, a right-handed pitcher, as their 26th player on the roster for the doubleheader against the Yankees. On Tuesday, Cumpton pitched six innings and allowed two runs for Triple-A Indianapolis. His ERA for Indianapolis is 1.41.
He didn't pitch in either game and was sent back to Triple-A after the twin bill.
Earlier this season, Cumpton started two games for the Pirates. He allowed six runs in 12 2/3 innings.
Orioles: Wieters gets PRP injection
Catcher Matt Wieters, who has been sidelined with a sore right elbow, had a platelet-rich plasma injection in the elbow last Monday, according to Orioles manager Buck Showalter.
After Wieters fully rests from the injection, the Orioles expect to get a more definitive idea about what's going on with the elbow. Showalter has said he would like to know by July 1 whether Wieters can return behind the plate this season.
Meanwhile, Rule 5 infielder Michael Almanzar had a second PRP injection in his right knee on Thursday.
• The Pirates posted the best Interleague record last season (15-5), going 9-1 on the road and 6-4 at home. They are 3-5 in Interleague Play this season after winning their second game against the Yankees on Sunday, but dropping the first two games of the series.
• Baltimore's J.J. Hardy matched a season high with three hits on Sunday against the Royals.
