The nine-time All-Star and former American League MVP went 0-for-4 over two seven-inning games.
"[He] felt fine, he is just getting into game shape and getting his timing down," Blue Jays manager John Farrell said. "Certainly not going to make too much [out of it], as he just starts to get into games."
Guerrero played a few innings in the outfield and also saw time at designated hitter. The Blue Jays wanted to get him in the field to help speed up the process of getting his body into baseball shape, but he will, in all likelihood, be used exclusively as a DH if and when he comes to Toronto.
The initial reports have all been positive, and Farrell spoke earlier in the week about how Guerrero has accelerated his promotion to the big leagues if all goes right, after general manager Alex Anthopoulos said following the signing that he figured Guerrero wouldn't be ready for the Majors until June at the earliest.
Guerrero, a 16-year veteran, hit .290 with 13 homers and 63 RBIs while posting a career low .733 OPS in 145 games with the Orioles last season.
