Baseball: Tanaka gives up homer, hangs tough in first spring start

CLEARWATER, Florida (Kyodo) -- Japanese right-hander Masahiro Tanaka allowed two hits including a solo home run in his first spring start for the New York Yankees on Thursday, but otherwise kept the Philadelphia Phillies' bats quiet in his three innings of a 4-3 win.

The 25-year-old Tanaka, who took the mound after heavy thundershowers delayed the game's start by 90 minutes, commanded the zone with his fastball and unleashed a nasty splitter to record his only strikeout. He threw a total of 41 pitches, 25 for strikes, and retired seven of 11 batters on ground balls.

The former Rakuten ace gave up a double to right-center in the second inning, and with two outs in the third served up a 3-1 fastball that Phillies infielder Freddy Galvis drove out of the park. Tanaka did not factor into the decision, as he finished his three innings with the Yankees down 1-0.

"I was able to get decent results even though I wasn't in great form," Tanaka said. "Hopefully, going forward, I can continue to do the same when necessary."
