Jackson went 3 1/3 innings and allowed four runs -- two earned -- on five hits. He struck out two batters and walked two others. Jackson said he didn't have any problems with his mechanics, but pointed out that he was out of sync in the fourth inning.
With two outs in the first, Clete Thomas hit what looked like a routine fly ball to left fielder Jason Michaels, but Michaels dropped the ball to extend the inning.
Michaels didn't make any excuses, stating that he just missed the ball.
The error would prove costly, as Ryan Raburn followed with a two-run homer to give the Tigers the early lead. Both runs were unearned for Jackson.
In the third inning, Austin Jackson scored the third run of the game on a single by Thomas. An inning later, Gerald Laird drove in Jhonny Peralta with a single to right field to make it a 4-1 game.
"Errors happen, mistakes happen. That's part of the game," Jackson said. "I got out of sync a little bit in the fourth inning, but that's why we are here in Spring Training -- working out the kinks and everything. But overall, I feel pretty good.
"It's the best I've felt. The results were not necessarily the best. I'm in Spring Training. We get caught up in results in Spring Training, when Spring Training is a time when you are getting ready for the season. That's what we have to be doing. The first game I had walks, so I'm not going to go kill myself."
