The Beatles song “Help!” rang out from the Phoenix Municipal Stadium sound system as Cubs bench coach Jamie Quirk tapped Scott Baker and took the ball from him.

Baker wanted to see how he’d react under these conditions and the Oakland A’s drew a crowd of 7,184 spotted in varying shades of green for a St. Patrick’s Day matinee. He walked off the mound after facing six hitters in a 12-6 loss, another step in his recovery from Tommy John surgery.

The Cubs already had Casey Coleman warming up in the bullpen when Chris Young, Oakland’s No. 3 hitter, lifted a ball over the left-field fence for a three-run homer in the first inning.

“Trust me, there were some nerves,” Baker said. “I haven’t done it in awhile. That’s a good thing. It means I still love this game and enjoy pitching and want to compete. At the same time, you have to combat those feelings and still make good pitches.”

The last time Baker pitched in a major-league game was Sept. 24, 2011, which doesn’t seem that long ago, until you realize that might as well be an eternity in baseball.

Remember that Theo Epstein and Jed Hoyer were running the Boston Red Sox and San Diego Padres back then, while Dale Sveum was the Milwaukee Brewers hitting coach. Baker didn’t throw a single pitch for the Minnesota Twins during the 2012 season. But the new management team at Clark and Addison saw his upside as a buy-low rotation piece.
