BALTIMORE (AP) — Chris Tillman pitched seven innings of four-hit ball to win his fourth straight decision, and the Baltimore Orioles breezed past the Cleveland Indians 8-0 Sunday night to complete a doubleheader sweep.

In the afternoon game, Ubaldo Jimenez tossed eight crisp innings and Baltimore got home runs from Jimmy Paredes and Manny Machado in a 4-0 victory.

The sweep boosted the Orioles to the top of the AL East by percentage points over Tampa Bay. Baltimore (41-34) has won 15 of 19 to move a season-high seven games above .500.

It was the first time since Sept. 6, 1974, that the Orioles registered shutouts in both games of a doubleheader, according to STATS. The opposition that day was also Cleveland.

Tillman (6-7) struck out six, walked none and reduced his ERA from 6.22 to 5.67. The right-hander hasn’t lost since May 31, even though he surrendered six runs in 1 1/3 innings at Toronto in his last start.

After Baltimore scored two unearned runs in the second inning, Chris Davis, Travis Snider and Chris Parmelee homered in a six-run fourth that made it 8-0.

Cleveland got only two runners past second base all day in absorbing its first doubleheader sweep since Sept. 8, 2009, against Texas. Jason Kipnis, who started the day with a 20-game hitting streak, was a collective 0 for 7 with four strikeouts.

Manager Terry Francona was ejected in the ninth inning of the second game for arguing a third-strike call.

The Indians summoned Toru Murata (0-1) from the minors to make his major league debut in the nightcap. Now in his fifth season in the Cleveland organization, the 30-year-old Japanese right-hander allowed five runs in 3 1/3 innings despite retiring the first five batters he faced.

David Murphy went 4 for 4 for the Indians in the second game.

In the opener, the Orioles collected their 5,000th win since the move from St. Louis to Baltimore in 1954.

Jimenez (7-3) allowed four hits, struck out seven and walked none in winning his fourth consecutive start. After going 6-9 with a 4.81 ERA last year, the right-hander owns a solid 3.09 ERA and leads the team in wins and strikeouts.

This is what the Orioles were looking for in February 2014 when they signed him as a free agent to a four-year, $50 million contract.

“We’re getting to see the guy we thought Ubaldo could be,” manager Buck Showalter said.

Jimenez came in 0-2 with an 8.10 ERA in three career starts against Cleveland, the team he played for from 2011-13 after winning a combined 34 games with Colorado the previous two seasons.

“Every time I take the mound, I feel like I can give the team a chance to win,” Jimenez said. “That’s what I did in 2010 and 2009, so I feel that’s what I am capable of doing right now.”

Jimenez outpitched Trevor Bauer (6-5), who gave up four runs, five hits and a walk over seven innings.

“It’s tough when they hit eight or nine balls hard,” Bauer said. “Usually I give up eight or nine hard hits in the course of like two or three games.”

The second game was a makeup of a rainout Saturday. Baltimore beat the Indians on Friday night and finished 5-1 against Cleveland, winning the season series for the first time since 2006.

Orioles: CF Adam Jones (sore right shoulder) started in the opener for the first time since June 20. He sat out the nightcap.
