HOUSTON (Ticker) -- Perhaps hung over from the Far East preseason tour, the Houston Rockets have needed a few games to get going. With two straight wins under their belt, they can get above .500 with a triumph over the winless Memphis Grizzlies on Tuesday at the Toyota Center.

Following a preseason trip to China for a pair of exhibition games, the Rockets opened the regular season with two lethargic losses. Houston got its first victory of the season vs. the Grizzlies on Friday at Memphis. In the 89-81 triumph, Tracy McGrady broke out for 30 points and a game-high nine assists.

In the Rockets' home opener the next day, McGrady scored 23 and Yao Ming produced 33 as the two stars began to showcase their overwhelming talent. The Rockets got a combined 25 rebounds from the pair in a 104-101 win over the Sacramento Kings.

Tuesday's meeting against the Grizzlies is the second of four straight for Houston at the Toyota Center.

Memphis has lost by an average of nearly 15 points a game thus far, including a 112-88 rout at the hands of the Dallas Mavericks on Saturday. In that loss, the Grizzlies were outrebounded, 53-36, and shot just 37.6 percent from the floor.

Overall, Memphis has averaged just 86.7 points per game - 26th in the league - with just three players in double figures. Pau Gasol is the only member of the Grizzlies to shoot 50 percent from the field for the season.

The Rockets swept the season series in 2003-04 and has won five straight vs. Memphis, including nine straight at home.
