Edinson Volquez will introduce himself to Daniel Murphy on Wednesday evening -- or to David Murphy, or to Dennis Murphy or whatever misstated name people unfamiliar with the Mets' left fielder can come up with. And perhaps by the end of the Mets' second game, Cincinnati will recognize it's D-A-N-I-E-L.

For now, Murphy is just the guy who provided the runs necessary for the Mets to win their Opening Day game on Monday, the guy who made the running catch in the gap in the sixth inning to deny the Reds a run in what became a 2-1 Mets victory, the guy who came back from an 0-2 count to hit a 3-2 fastball over the right-center-field wall, the guy identified as David in the postgame media notes the Reds distributed and as Dennis on the Reds' radio broadcast.

The Mets suspect the National League will become more familiar with their No. 2 hitter -- quickly and completely.

What Murphy demonstrated Monday is what the Mets expect to see against Volquez on Wednesday and Bronson Arroyo on Thursday -- even though Murphy has faced neither in his brief big league tour -- and all others.

"Of course it will be to his advantage when he gets to know the pitchers," batting coach Howard Johnson said. "But look what he's done so far, and he doesn't know many.

"He seems to learn with every pitch. He learns on the bench and in the on-deck circle."

Murphy had never faced Reds starter Aaron Harang or the Reds' bullpen before Monday. He grounded out to shortstop -- advancing Jose Reyes to third base in the first inning -- flied out to left in the third, hit the home run in the fifth against Harang, drove in a run in the sixth against left-hander Daniel Ray Herrera with an infield out and struck out in the ninth against Francisco Cordero. He had one hit in five at-bats and more impact than any other player on either team.

"[Murphy is a] patient hitter," Johnson said. "A guy who takes pitches and spoils pitches as well as he does can get by without knowing the guys he's facing for a while. He makes adjustments like a veteran ... better than some veterans.

"It's going to be [great] to watch him grow as a hitter. He has an idea every time he goes to the plate, and he comes back with better ideas."

Pitching matchup
CIN: RHP Edinson Volquez (17-6, 3.21 ERA in 2008)
Volquez had a breakout season in his first year with the Reds, making the All-Star team and finishing in the National League's top 10 in wins, ERA and strikeouts. He did seem to tire in the second half, with a 4.60 ERA after the break (2.29 in the first half). The key for Volquez is command, and cutting down his 93 walks from a year ago will allow him to be more efficient and pitch deeper into games. He was terrific in camp this spring, allowing just one run in 19 innings.

NYM: RHP Mike Pelfrey (13-11, 3.72 ERA in 2008)
Pelfrey won neither of his two starts against the Reds last season, taking the loss in one of them. He was more effective in the loss, at Shea Stadium -- two runs, both earned, in six innings -- than he was at Great American Ball Park in a no-decision the Mets won. The Reds scored five runs in seven innings, producing three of the 12 home runs he allowed all season in a five-inning sequence. He was rocked Thursday in his final exhibition game start, allowing 10 hits and eight runs against the Orioles. Pelfrey had missed one start because of an injury to his left leg and had another start ended after 13 pitches because of rain.
