BALTIMORE -- Before Koji Uehara's last start on Thursday, Orioles manager Dave Trembley said that he was looking for his pitcher to throw about 75-80 pitches, in order to see how the right-hander would perform coming off his injury.

Five innings and 81 pitches later, Uehara's first outing since suffering a left hamstring injury on May 23 was over.

He'll make his second start since returning from the disabled list Wednesday night against the New York Mets.

In his first start off the DL, Uehara allowed four earned runs on seven hits, striking out three and issuing just one walk.

But that was against a Seattle Mariners team that was 11th in the American League in team hitting, batting a collective .257. The Mets enter Wednesday's game second in the National League and third in the Major Leagues batting .278.

Leading the attack against Uehara will be the Mets' duo of Carlos Beltran and David Wright. Beltran is second in the NL with a .344 batting average, trailing only Wright, who his hitting .364. Right-handed batters are hitting .308 against Uehara this season.

Uehara was placed on the 15-day disabled list on May 27 with a left hamstring injury. He admitted that his hamstring has been an issue for a substantial part of his career, but it is something he has tried to cope with.

Uehara is just 2-4 this season and hasn't won a start since an April 13 start against Texas.

Pitching matchup
BAL: RHP Koji Uehara (2-4, 4.37 ERA)
Uehara was sharp through the first two innings against the Mariners on Wednesday, issuing only one walk and striking out two. The third inning began after a nearly 30-minute rain delay, upon which the Mariners scored three runs.

NYM: RHP Tim Redding (0-2, 6.18 ERA)
He doesn't have a win to show for it, but things have been getting better for Redding, who had poor outings in his second and third starts after returning from the DL. He held the Nationals to one run in six innings on June 5 and the Phillies to three runs in seven innings his last time out Thursday. He has walked only two batters in his past 13 innings after walking 10 in his first 14 2/3
