=== Pirates aim for sweep of Cards; expected to debut Morneau ===
 
 (Sports Network) - Securing their first winning record since 1992 no longer
 seems the goal for the Pittsburgh Pirates. It is playoffs or bust for these
 Bucs.
 
 Having pulled off their second trade of the week, the Pirates are likely to
 debut Justin Morneau on Sunday afternoon as they shoot for a big three-game
 sweep of the St. Louis Cardinals.
 
 After taking the opener of this set, the Pirates cruised into Saturday tied
 atop the NL Central with the Cardinals and then made waves by trading
 outfielder Alex Presley and a player to be named later or cash to the
 Minnesota Twins for Morneau, the 2006 AL MVP.
 
 It was a big move for the Pirates, who have not made the playoffs or had a
 winning record since a 96-66 campaign in 1992. The trade also came after
 Pittsburgh had acquired depth on Tuesday by getting outfielder Marlon Byrd and
 catcher John Buck from the New York Mets.
 
 Morneau arrived in Pittsburgh during Saturday's 7-1 victory, but did not play.
 He hit .259 with 17 homers and 74 RBI in 127 games with the Twins this year.
 
 "There's a lot of emotion and adrenaline I hadn't had in a while," Morneau
 told Pittsburgh's website. "I'm excited by this opportunity, of doing
 something every day to help this team win, to do whatever it takes to get in
 the playoffs."
 
 Morneau probably liked what he saw on Saturday, when Russell Martin hit a
 three-run homer and A.J. Burnett hurled seven innings of one-run ball. He
 added an RBI single, while Neil Walker had three hits and an RBI in
 Pittsburgh's third victory in four games.
 
 "We're heading in the right direction but we've got a long way to go," said
 Pittsburgh manager Clint Hurdle. "One of the things I share with new players
 coming in here is to fear nothing and respect everything and that's the way
 we'll keep doing it."
 
 The Pirates carry a one-game lead over the Cardinals in the division and are 3
 1/2 games up on the third-place Cincinnati Reds. They are 10-5 versus St.
 Louis this season, winning seven of nine in Pittsburgh.
 
 These division rivals will meet just one more time this regular season, from
 Sept. 6-8 in St. Louis.
 
 Lance Lynn was tagged for all seven runs on 10 hits and three walks in just
 four innings of work for the Cardinals, who have scored just one run in losing
 their past three games.
 
 "They hit a couple of the ball really hard against Lynn today," said St. Louis
 manager Mike Matheny. "This was not what he was looking for when he went out
 there today."
 
 Matheny hopes to salvage the finale of this series behind Joe Kelly, who is
 unbeaten since getting put into the Cards' rotation full time in early July.
 
 Kelly is 6-0 with a 2.24 earned run average since the switch and picked up his
 third straight winning start on Tuesday, a 6-1 decision over Cincinnati. The
 right-hander hurled six frames and gave up just one run on eight hits and
 three walks.
 
 "It's just hard to complain with what he did today," said Matheny. "He came
 out with a lot of confidence again."
 
 Kelly's current run includes a 13-0 victory at Pittsburgh on Aug. 1, when he
 scattered three hits and four walks over six scoreless innings. The 25-year-
 old is 6-3 with a 2.91 ERA in 31 total appearances this year, including 10
 starts.
 
 Kris Johnson is expected to step in to make a start for the Pirates today in
 place of the struggling Jeff Locke, who was sent to the minors for a spell
 earlier this week. The 2013 All-Star was 0-2 with a 7.02 ERA over his last
 seven starts and gave up five runs over 4 2/3 innings versus Milwaukee on
 Tuesday.
 
 Johnson is 10-4 with a 2.39 ERA in 26 games (21 starts) with Triple-A
 Indianapolis this season and will make his first Major League start and second
 career appearance.
 
 The 28-year-old lefty pitched the final six frames of a 16-inning defeat
 versus Arizona on Aug. 18, allowing two runs to take the loss.
