Willie Randolph was set to depart New York for a West Coast road trip still in charge of the Mets, while the Yankees headed back to the Big Apple without their staff ace.

Pedro Martinez pitched six sharp innings, pinch-hitter Robinson Cancel got his first major league hit in nearly nine years and the New York Mets beat the Texas Rangers 4-2 Sunday for a doubleheader split. Kevin Millwood led the Rangers to an 8-7 victory in the opener.

Before the first game, Randolph said he had no idea what combination of results in the twinbill was needed to remain the club's manager.

"We wanted to make the trip a little more pleasant," Randolph said afterward. "I'm glad I'm going."

He then quickly added, "Maybe I'm speaking a little too soon."

Things are just as uncertain for the Yankees and ace Chien-Ming Wang, who left the clubhouse on crutches after spraining his right foot running the bases in a 13-0 rout of Houston. An MRI exam is planned for Monday and manager Joe Girardi said Wang will miss at least one start.

"I feel sore," Wang said through a Yankees spokesman. "Of course I'm disappointed. On Tuesday, when I know more, I will talk then."

In other games Sunday, it was St. Louis 7, Philadelphia 6 in 10 innings; Cleveland 7, San Diego 3; Boston 9, Cincinnati 0; Colorado 5, the White Sox 3; the Chicago Cubs 7, Toronto 4; Detroit 5, the L.A. Dodgers 4; the L.A. Angels 2, Atlanta 0; Florida 9, Tampa Bay 3; Milwaukee 4, Minnesota 2; Oakland 5, San Francisco 3; Kansas City 8, Arizona 3; Washington 6, Seattle 2; and Pittsburgh 5, Baltimore 4 in 10 innings.

The Mets are heading west for the second time in two weeks and Randolph said his bags were packed for the trip. After returning from their last trip with two wins in seven games, rumors had intensified that Randolph could lose his job by the end of the series against Texas.

Evidently taking three of six from the Rangers and Diamondbacks was enough for now.

"These are our coaches today," Mets general manager Omar Minaya said Sunday night. "They are our coaches. As the GM I leave myself room to evaluate things. I think we're not playing to our potential. I always leave room to evaluate things."

Martinez (2-0) gave up six hits and two runs — one earned — in his third start since coming off the disabled list on June 3 to win the second game, getting a big assist from the bullpen and Billy Wagner's first save after blowing three straight chances.

Kason Gabbard (1-3) gave up eight hits and four runs in 5 2-3 innings for the Rangers.

The Mets' bullpen wasn't nearly as good in the opener, when the Rangers turned a 3-2 lead into an 8-2 advantage.
