BALTIMORE -- The Orioles remained undefeated on Sunday with a 5-3 win over the Rays at Orioles Park.
The 5-0 start is just the Orioles' second since moving to Baltimore in 1954. The O's started the season 5-0 in 1970 (and won the World Series that year).
The Orioles travel to Boston on Monday to clash with the Red Sox and their ace, David Price. Right-hander Yovani Gallardo, who is in his first season in Baltimore, will be tasked with keeping the soaring Orioles perfect on the season.
• Orioles' perfect start on the line at Fenway
"It's the start of the season," Orioles third baseman Manny Machado said. "We started off with a great homestand. We started off the year pretty well. Let's keep this ball rolling."

The O's got busy in the second when Jonathan Schoop doubled to left off Rays starter Jake Odorizzi to drive home their first run. Joey Rickard added a sacrifice fly, before Manny Machado belted a two-run homer to left-center field to put the Orioles up 4-0. They added an insurance run in the eighth when Machado scored on a wild pitch by Erasmo Ramirez. Machado finished 4-for-4 with two RBIs and two runs scored, just a triple shy of the cycle.
"The Machado pitch was just a bad pitch selection," Odorizzi said. "It was a cutter. I should have known better than to throw it in there. It just kind of leaped back over the plate. You saw what he did with it."
Corey Dickerson's third home run of the season, a solo shot in the fourth, cut the lead to 4-1, and Evan Longoria and Steve Pearce had RBI singles in the fifth to make it a one-run game. But the Orioles' bullpen of Brad Brach, Mychal Givens, Darren O'Day -- who escaped a bases-loaded jam in the eighth -- and Zach Britton shut out the Rays for the final 4 1/3 innings to preserve the win.

MOMENTS THAT MATTERED
Machado leads O's power: The Orioles kept the power coming on Sunday. Machado belted a two-run homer that sparked a four-run second inning for his third home run in the first five games. The Orioles now have hit eight homers in their first five games, a big reason for the 5-0 start.
Dickerson extends the streak: Dickerson's solo home run off Orioles starter Vance Worley in the fourth extended the Rays' club-record streak to 20 consecutive games in which they have homered, dating back to Sept. 20 against the Orioles. It's the longest home run streak by any team since the Mariners went deep in 23 consecutive games from June 20-July 19, 2013.

Interference on the defense: Dickerson reached first in the fifth with two outs when he swung at a pitch from Worley and hit catcher Matt Wieters' mitt. The catcher's interference call kept the inning alive for Pearce to single home the Rays' third run.
Welcome to the Major Leagues, Kim: Orioles left fielder Hyun Soo Kim went 2-for-3 with a run scored in his Major League debut. Both of his hits were infield singles, the first coming on a slow roller between the mound and third base in the second inning, and the second coming in the seventh on a grounder that shortstop Brad Miller couldn't quite make a play on.

QUOTABLE
"I will keep that in a safe box, Make sure no one takes it." -- Kim on what he'll do with the ball from his first hit
"Felt like we should have gotten a few runs early to help [Odorizzi] out, but we battled. It's early in the season and I think once everything starts clicking I think everything can start going a lot differently." -- Dickerson on Sunday's loss
SOUND SMART WITH YOUR FRIENDS
Sunday's first-pitch temperature of 44 degrees was the coldest the Rays have played in since April 29, 2014 at Boston when the first-pitch temperature at Fenway Park was 43 degrees.

UNDER REVIEW
In the bottom of the fifth, Odorizzi threw over to first base to try to pick off Machado, as he was leading off the bag. First-base umpire Greg Gibson signaled safe when Pearce slapped the tag on Machado. Pearce immediately signaled to the Rays' dugout to challenge the call, which Rays manager Kevin Cash did. After a 1-minute and 23-second delay, the call on the field was overturned.
WHAT'S NEXT
Rays: After having an off day on Monday, the Rays will open a three-game series with the Indians on Tuesday at 7:10 p.m. ET at Tropicana Field. Matt Moore will make his second start of the season. He allowed three runs in a five-inning no-decision against the Blue Jays on Wednesday in his first start.
Orioles: The Orioles hit the road for the first time this season on Monday, when they meet the Red Sox in their home opener on Monday at 2:05 p.m. at Fenway Park. Gallardo will get his second start of this season after giving up one run in five innings during last Wednesday's win over the Twins.
