BALTIMORE — Moments before he made history with his final swing in an incredible four-homer performance, Josh Hamilton stepped to the plate in the eighth inning with a surprising sense of calm.

Hamilton, the Texas Rangers’ slugger, had never before hit more than two home runs in a game, and he already had three. So as he took his place in the batter’s box against Baltimore right-hander Darren O’Day, Hamilton already had a feeling of accomplishment.

“I just went up like it was any other at-bat because if I don’t hit one,” Hamilton reasoned, “I’ve still had a really good night.”

It turned out to be unforgettable.

Hamilton became the 16th player to hit four home runs in a game, launching a quartet of two-run drives against three pitchers to carry the Rangers to a 10-3 victory Tuesday night.

Hamilton homered off Jake Arrieta in the first and third innings, added another off Zach Phillips in the seventh and topped it off with a shot against O’Day.

“Obviously it’s, other than being in the World Series, the highlight of my big-league career,” Hamilton said. “I was saying after I hit two I’ve never hit three in a game before, and what a blessing that was. Then to hit four is just an awesome feeling.”

Hamilton also doubled. His 18 total bases is a single-game AL record, and his eight RBI are a career high.

The last player to hit four homers in a game was Carlos Delgado on Sept. 25, 2003, for Toronto against Tampa Bay.
