After beginning the season with two strong outings, the Tigers right-hander has been roughed up in his last two, lasting only one inning against the Rangers and then giving up five runs in 6 2/3 innings against the Mariners.
On Tuesday, Porcello looks to bounce back from his two subpar outings against the Royals after Monday's game was postponed due to rain.
Porcello has been at his best in May throughout his four-year career, going 10-4 with a 2.66 ERA in 14 career May starts -- easily his most successful month. Another good May outing would greatly help the Tigers, who sit at .500 after losing eight of their last 10. The slow start for most of the clubs in the division has also benefited the Royals, another team waiting to click.
Kansas City bounced back from its 12-game losing streak with three consecutive wins before Sunday's setback. With the loss to the Twins in their series finale, though, the Royals dropped into a tie with Minnesota for the American League's worst record at 6-15.
As they look to get back in the win column, the Royals will turn to the same hurler that helped the club snap that long skid -- Luke Hochevar. The right-hander allowed just two runs over 6 1/3 innings against the Indians on Wednesday.
"He kept us in check the whole game," Tribe manager Manny Acta said. "We couldn't do anything against him when he was out there."
Royals: Sanchez start pushed back a day
Jonathan Sanchez is expected to pitch in the Detroit series. Manager Ned Yost's plan is to use Sanchez in Wednesday's game, assuming he's recovered from his weekend illness.
"We'll give him an extra day to recover," Yost said.
Tigers: Fister's rehab start set, could return Monday
Doug Fister will make his first rehab start for Triple-A Toledo on Wednesday at Fifth Third Field against Pawtucket. Beyond that, manager Jim Leyland said Fister could return to start the Tigers' opener of a nine-game road trip in Seattle on Monday.
Fister threw 50 pitches in his first bullpen session Thursday then exceeded that mark in his last session Saturday. He's expected to work with a normal pitch count in Wednesday's rehab outing.
Monday's game will be made up Sept. 24, which was a scheduled off-day for both teams.
With Monday's postponement, Justin Verlander will face Sanchez on Wednesday.
Miguel Cabrera is 15-for-29 (.517) with two homers and nine RBIs in his career against Hochevar. The average is Cabrera's highest against any pitcher whom he has recorded 25 or more at-bats.
Of the 28 teams Prince Fielder has faced, the Royals are one of four (the White Sox, Yankees and Rays being the others) that he has never homered against. Fielder has never faced the Athletics or the Brewers.
The Tigers, who are 3-0 against the Royals this season, are 5-1-1 in the last seven season series with Kansas City.
