Hyun Soo Kim singles in first major league at-bat (O's win 5-3)

Fans applauded Hyun Soo Kim today as he stepped to the plate in the bottom of the second inning. A much different response from opening day.

Kim's first major league at-bat came immediately after Pedro Alvarez scored from first base on Jonathan Schoop's double into the left field corner to break a scoreless tie. Aggressive send by third base coach Bobby Dickerson. Aggressive reaction from fans who were thrilled by the run and the sun.

Kim fell behind 0-2 on a foul ball and called strike, then beat out a nubber to the left side for his first hit, the ball glancing off the glove of Rays starter Jake Odorizzi. All three pitches were 89 mph fastballs.

You may recall that Kim's first two hits in spring training were infield singles. He's mastered it.

The ball was tossed into the dugout, where Kim can retrieve it and keep as a souvenir.

The Orioles scored four runs in the inning, the last two on Manny Machado's third home run of the homestand. Rule 5 pick Joey Rickard lifted a sacrifice fly to center field after Kim's single.

Alvarez also picked up his first hit with the Orioles, ending an 0-for-12 stretch, when he reached on an infield single into the shift leading off the second. He initially was called out, but former Oriole Steve Pearce dropped the ball while stretching for the throw.

It didn't take long for the ball to find Kim in left field. Evan Longoria sent a liner in his direction with two outs in the first inning.

It wasn't a can of corn, but Kim made the play.

Kim also ran down Logan Forsythe's liner into left-center field in the third inning. He's 1-for-1 at the plate and 2-for-2 in the field.

Rickard led off the bottom of the first with a single, his eighth hit in 16 at-bats. He's going to cool off eventually. Nobody hits .500. But he's on an impressive roll and fans continue to eat it up, chanting his name each time he steps to the plate.

Machado also singled, but both runners were stranded.

Vance Worley, making his Orioles debut, retired the side in order on nine pitches in the first inning and stranded Corey Dickerson in the second after a leadoff double. Eighteen of his 23 pitches were strikes over two innings.

Worley, Alvarez, Rickard and Kim all contributing today. Executive vice president Dan Duquette must be smiling.

Update: Corey Dickerson homered off Vance Worley in the fourth to reduce the lead to 4-1. Worley stranded two runners in the inning after a two-out walk and single.

Worley has thrown 59 pitches in four innings.

Update II: Worley was charged with three runs and seven hits in 4 2/3 innings, with one walk, five strikeouts and a home run. He threw 79 pitches, 50 for strikes.

A catcher's interference call on Wieters extended the fifth inning and cost him a run on Pearce's RBI single.

Update III: The Orioles defeated the Rays 5-3 before 23,101 at Camden Yards.

The Orioles have matched their best start at 5-0, tying the 1970 team that won the World Series.

Manny Machado scored a big insurance run in the eighth on a wild pitch. He went 4-for-4 with a double and home run.

Brad Brach got the win after retiring all four batters he faced. Darren O'Day escaped a bases-loaded jam in the eighth by striking out Hank Conger, and Zach Britton recorded his second save.
