Hunter Pence hit a blistering go-ahead home run in the eighth inning and the Houston Astros used two smart fielding plays late to beat New York 4-3 Thursday night, giving the Mets their worst home start ever.

The Mets fell to 1-8 at Citi Field. They began 1-7 at the Polo Grounds during their 1962 expansion season before winning their next home game.

The Mets’ seventh straight home loss dropped them to 5-13 overall, their poorest start since going 3-15 in 1964, according to STATS LLC.

Astros reliever Jose Valdez made a sweeping tag at home to end the Mets’ eighth-inning comeback. In the ninth, after Jose Reyes got his fourth hit, Josh Thole popped up a bunt and closer Brandon Lyon threw to first for the double play.
