DUNEDIN, Fla. (AP) _ Daryle Ward went 4-for-5 with a solo homer as the Houston Astros beat the Toronto Blue Jays 13-6 Wednesday.

Charlie Hayes, Richard Hidalgo and Morgan Ensberg also homered for the Astros, who had 16 hits. Ensberg who went 2-for-2 was reassigned to the Astros' minor league camp after the game.

Toronto starter Chris Carpenter left the game in the second with a mild mid-back strain. He allowed one run and one hit in 1 2-3 innings.

``I could feel it when I was in the bullpen,'' Carpenter said. ``I only feel it when I get full extension when I pitch. I'll shut it down for couple of days but I'm still on schedule to do my normal work.''

Astros starter Octavio Dotel (1-2) allowed three runs in five innings to get the win.

Shannon Stewart and Ryan Thompson homered for Toronto. Thompson's shot came in the ninth inning off Astros closer Billy Wagner.
