Pittsburgh going for the sweep in Phoenix. Would be the Pirates' first ever three game sweep in Arizona. Pirates previously took a two game sweep at Chase Field in 1998. Francisco Liriano also aims for his first win of the season.

"Liriano, Hellickson set for battle of veteran starters

When Francisco Liriano starts for the Pirates in Sunday's series finale against Arizona, he'll be working off quite a checklist.
Getting a series sweep for the Bucs and his own first victory of the season are on that list, but topping it is yet another personal item: The former American Leaguer has faced 29 of the 30 MLB teams (all but Miami), and has at least one win over all of them except for the D-backs, although this will be only his third career start against them.
Opposing the veteran lefty will be Jeremy Hellickson, who likewise has never beaten Pittsburgh, but has a better excuse for that: This will be the former Tampa Bay righty's first start against the Pirates. Three Bucs have faced him before and two of them -- catcher Chris Stewart and outfielder Corey Hart -- figure to be in Sunday's lineup.
Things to know about this game
• Hart could get a rare start, most likely in right field. Hart's primary role with the Pirates is platooning at first base with Pedro Alvarez -- but with the Bucs having faced only one lefty starter in the season's first 18 games, manager Clint Hurdle has to hunt other opportunities to keep Hart sharp.
• In 2004, Hellickson and Pirates outfielder Andrew McCutchen were teammates on Team Florida, a high school select team.
• For whatever reason, Liriano has been a better power pitcher on the road with the Pirates. In 174 innings, he has fanned 199, compared to 162 in 167 1/3 innings in PNC Park.
