The New York Yankees would like to be more consistent at the plate but are confident in a tight game when David Bednar is on the mound.

The Yankees certainly felt good about Bednar on Sunday night when they eked out a home win over the Los Angeles Dodgers. They hope there are situations this week to use him against his former team starting Monday in the opener of a three-game series against the visiting Pittsburgh Pirates.

New York is 2-9 in its 11 home games after getting a tiebreaking homer from Jazz Chisholm Jr. in the eighth inning of a 2-1 victory in the second game of Sunday's doubleheader against the Dodgers.

'We got to be more consistent offensively, first and foremost,' Yankees manager Aaron Boone said after his team stranded 11 runners in the win. 'That's been the biggest thing that I think has kind of ailed us through these few weeks.'

The Yankees earned the win thanks to Bednar, who recorded the final five outs.

Entering the series against the team which dealt him to the Yankees at last season's trade deadline, Bednar is on a career-best 20 2/3 inning scoreless streak in his past 17 outings. During those games, opponents are hitting .103, and it is the longest active streak in the big leagues.

'I faced Bednar a lot in my career before coming over here and I always thought he was a really good pitcher,' Chisholm said. 'His stuff is really lights out. Combined with the way that he has just great composure every time he goes out there and trusts his stuff, it's amazing.'

The Pirates are 8-3 in their past 11 games after Sunday's 7-1 win at Cleveland. Pittsburgh has scored at least five runs eight times in that span, and is hoping it can do enough at the plate to avoid facing Bednar, who notched 101 saves in five seasons before the trade.

Among the key figures for Pittsburgh's surge at the plate is rookie Esmeryln Valdez, whose two-run homer in the ninth inning was his 12th in 31 games.

Valdez also has an RBI in seven straight games and 20 RBIs this month.

'It's the professionalism of the at-bats,' Pittsburgh manager Don Kelly said. 'He's not going up there necessarily trying to hit the home runs. He's going up there to hit, and he's got the power to leave anywhere in the yard. It's been really impressive what he's been able to do in such a short amount of time.'

The right-handed hitting Valdez is hitting .371 off left-handed pitching. He will face New York southpaw Ryan Weathers (3-7, 4.15 ERA), who is allowing a .234 average to right-handed batters.

Weathers is 0-2 with a 5.73 ERA in his past three outings but allowed one run on six hits in 5 1/3 innings a week ago in Washington, marking the eighth time this season that he allowed one earned run or fewer.

Weathers is 0-2 with a 2.77 ERA in three career appearances (two starts) against Pittsburgh.

Pittsburgh's Braxton Ashcraft (9-3, 3.49) is making his first career start against the Yankees and will attempt to rebound from allowing five runs for the second time in three starts. Ashcraft is 4-0 with a 4.08 ERA in his past five outings and surrendered five runs on five hits in five innings in a no-decision during Pittsburgh's 7-6 win over Milwaukee on July 11.
