The Tigers made their expected rotation tweak a day ahead of time, sending rookie left-hander Andy Oliver to Triple-A Toledo Monday afternoon to make room for right-hander Armando Galarraga.
The move brings back Galarraga ahead of his scheduled start Tuesday against Texas. The Tigers optioned Galarraga to Toledo a week and a half ago with the express intent of getting him some pitching time last week before rejoining the rotation. Galarraga pitched three scoreless innings of relief Friday at Scranton/Wilkes-Barre.
With Oliver out, Rick Porcello officially remains in the Tigers rotation after returning for what was originally characterized as a spot start Saturday night at Cleveland. The Tigers haven’t said when Porcello would start next, but his rotation spot would fall Thursday afternoon against the Blue Jays at Comerica Park. Porcello pitched his way back with eight innings of one-run ball with six strikeouts against the Indians, by far the best performance by a Tigers pitcher over the weekend.
For Oliver, the move ends a five-start stint in the big leagues that showed his potential as a power left-handed starter, but also showed the learning curve he still has to make in his first full pro season. The 22-year-old gave up two earned runs over six innings in each of his first two starts, but lost them both, before struggling in each of his last three outings. He went 0-4 with a 7.36 ERA, allowing 18 earned runs on 26 hits over 22 innings with 13 walks and 18 strikeouts.
