The Revolution (7-16-8) are winless in their last three games.
Clark gave Houston a 1-0 lead in the 77th minute, taking a chip pass from Brad Davis into the right 6-yard box and one-timing it off the far post and in.
Clark had a chance to double the lead in the 81st minute, but his shot from 14 yards in the middle was saved by Revolution goalkeeper Bobby Shuttleworth. Cam Weaver hit a shot from 14 yards on the right off the near post a minute later.
Davis had a shot from the upper left box stopped by a diving Shuttleworth in the 89th minute.
Garcia made it 2-0 in second-half stoppage time, taking a cross from Warren Creavalle and volleying it inside the far post.
The Revolution had a couple of chances in the 18th and 19th minutes to try to take the lead, but Benny Feilhaber had a free kick from 25 yards left of the middle batted over the crossbar by Houston’s Tally Hall. Off the ensuing corner kick, Darrius Barnes had two shots in front of the net, but Hall knocked both attempts out of the box.
Red Bulls 4, Toronto FC 1 — Kenny Cooper broke out of a bit of a scoring drought, scoring his first two goals since Aug. 19, and New York beat visiting Toronto to solidify its chances to earn an Eastern Conference playoff spot. Thierry Henry scored a goal and set up three others.
