John Castino hit a two-run single in the seventh inning and Ken Schrom gave a solid pitching effort against his former teammates as the Minnesota Twins beat the Blue Jays, 4-3, yesterday in Toronto.

In his first game against Toronto since the Blue Jays released him at the end of last season, Schrom (5-2) gave up two runs and seven hits in 6 1/3 innings. Ron Davis pitched the last two innings to earn his 10th save, yielding a two-out, bases-empty homer in the ninth to Jorge Orta.

"I really feel that they did give up on me," Schrom said of the Blue Jays. "It provided me with some extra inner motivation today."

Trailing, 2-1, in the seventh, the Twins scored three runs on five hits off Dave Stieb (10-5). Gary Gaetti led off with a double that center fielder Lloyd Moseby lost in the sun. Gaetti scored one out later on Ron Washington's single to center. After Washington was caught stealing, Scott Ullger and Rusty Kuntz singled and scored on Castino's single to short left field that Dave Collins had trouble handling.

Stieb gave up 11 hits and struck out nine to raise his league-leading strikeout total to 101.
