Rapid Reaction: Rockies 2, Mets 1

Recap | Box Score | Photos

WHAT IT MEANS: The Mets lost the opener to a two-city trip to Denver and Houston and matched a season high by slipping 8½ games behind the first-place Philadelphia Phillies.

Willie Harris snapped an 0-for-13 drought since April 27 by singling as a pinch-hitter in the ninth, but he was caught stealing. He also had been 0-for-12 as a pinch-hitter this season.

CAPPER: Chris Capuano offered a quality outing, but served up a tiebreaking line-drive homer into the left-field corner to Chris Iannetta in the seventh.

Capuano had escaped a bases-loaded jam in the first inning when he retired Todd Helton on a 4-6-3 double play. The other run against Capuano aside from Iannetta’s homer -- which opened the game’s scoring -- came in the fifth. That inning, Iannetta led off with a hustling double to left-center and scored on a two-out single by Dexter Fowler past diving third baseman David Wright.

Capuano’s final line: 6.2 IP, 2 R, 2 ER, 5 H, 3 BB, 4 K.

REPLAY, ANYONE? With runners on the corners and the score tied at 1 in the top of the seventh, Carlos Beltran sent a grounder to Helton. The first baseman threw to the plate. Ump Mike Winters ruled Daniel Murphy out attempting to score from third base. While the ball beat Murphy by a comfortable margin, replays appeared to show the tag was late and Murphy was safe.

The Mets, however, did not protest. In reality, they had squandered limited earlier opportunities.

Ike Davis produced the Mets’ first hit against Rockies starter Jhoulys Chacin with two out in the fourth. The Mets ended up loading the bases that inning when Jason Bay and Jason Pridie then consecutively walked. However, Josh Thole grounded out to first base to end the threat.

The Mets’ lone run came in the sixth after Beltran walked and Davis produced the team’s second hit, which advanced Beltran to third base. Bay then sent a chopper to the hot corner. Third baseman Ian Stewart’s only play was to first base, and the throw was high for an error, as Beltran scored.

YER OUT: Thole threw out his fifth runner in 32 attempts when he successfully caught Ryan Spilborghs to end the seventh inning, after Taylor Buchholz had replaced Capuano.

K-ROD TRACKER: Francisco Rodriguez did not appear. He has finished 11 of the Mets’ first 35 games. K-Rod needs 44 games finished in the team’s final 127 games for his contract to vest at $17.5 million for 2012. Rodriguez is on pace for 51 games finished, four shy of the triggering milestone.

WHAT’S NEXT: Mike Pelfrey (2-3, 6.06 ERA) opposes right-hander Jason Hammel (3-1, 2.63) at 8:40 p.m. ET Tuesday. Terry Collins said R.A. Dickey likely will be held back from his normal between-starts bullpen session to potentially be available in relief. Dickey pitched a scoreless inning of relief on April 17 at Atlanta between starts. Collins also indicated he plans to get Ronny Paulino a start in the series, despite the Mets drawing three Rockies right-handed starting pitchers.
