Liriano, Morneau help Twins beat Cardinals 6-2

ST. LOUIS — Francisco Liriano pitched seven strong innings, Justin Morneau hit a three-run home run and the Minnesota Twins beat the St. Louis Cardinals 6-2 on Sunday.

Joe Mauer singled his first two at bats for the Twins to hike his average to .400 before a double-play ball, a groundout and a strikeout dropped him to .394. Jason Kubel had three hits and an RBI and Brendan Harris had two RBIs to help Minnesota take two of three from St. Louis while completing interleague play at 12-6.

Joe Nathan got the last out for his 19th save in 21 chances and 14th in a row after the Cardinals put runners on first and third in the ninth.

St. Louis missed a chance to load the bases with one out when Joe Thurston was caught in a rundown between second and third on pinch hitter Chris Duncan’s single off R.A. Dickey.

Mark DeRosa, acquired Saturday night from the Indians for reliever Chris Perez and a player to be named, batted cleanup for the Cardinals and had three groundouts and a walk for the Cardinals. He contributed defensively with a diving catch in left field that robbed Morneau of extra bases in the eighth.

Ryan Ludwick had two hits and an RBI for the Cardinals, who had three throwing errors resulting in two unearned runs. They’ve lost four of five, three against lefties, and entered with a .228 average against left-handers.

Liriano (4-8) has won his last two starts during a turnaround June, and allowed two runs and four hits while striking out six and walking two. He retired his first 11 hitters and the Cardinals were hitless before Ludwick and Rick Ankiel opened the fifth with doubles, the latter on a broken bat, for a run. Jason LaRue’s RBI single made it three straight hits before Liriano recovered to retire six in a row.

Denard Span reached on shortstop Tyler Greene’s throwing error and Mauer singled with one out before Morneau, 3 for 18 with one RBI the first five games of a nine-game trip, hit a drive to right estimated at 432 feet to put the Twins ahead 3-0. Morneau’s first homer since June 9 was only the third allowed all season by Joel Pineiro (6-9), and first in 10 starts.

Pineiro allowed five runs, three earned, in 6 2-3 innings. He’s the only member of the Cardinals’ rotation to get a decision in every start.
