The White Sox enter Tuesday having won six straight games and 10 of their last 11, outscoring the opposition 78-41.
"[Adam] Dunn is swinging it a lot better this year and obviously [Paul] Konerko is hot right now and [A.J.] Pierzynski is hot right now," Shields said Monday. "They've got a good team over there, you can't take them lightly."
Shields, who is 6-2 with a 3.63 ERA this season, has his track record working against him. He is 3-2 with a 4.70 ERA in nine career starts against Chicago. However, the 30-year-old right-hander is coming off one of his season's best outings.
Facing the Blue Jays, Shields took a no-decision as he yielded three runs -- two earned -- on seven hits while striking out 10 in 7 1/3 innings. He exited the game in line for a win before Joel Peralta allowed a game-tying home run.
"I thought James Shields was really, really good," manager Joe Maddon said after the game. "He deserves a better fate than that."
Shields will be opposed by right-hander Philip Humber, who is 1-2 with a 5.80 ERA. Humber is still searching for his first win since throwing a perfect game against the Mariners on April 21. He's posted an 8.21 ERA since that outing and allowed five runs in 4 1/3 innings against the Twins his last time out.
"I've got to figure out what's going on," Humber said after the game. "Even though I had good results in the first couple innings there, I didn't feel like I was throwing the ball the way I need to throw the ball to be successful."
White Sox: Konerko just keeps rolling
Paul Konerko is currently riding a 14-game hitting streak and is pacing the Majors with a .395 batting average. He is batting .407 (35-for-86) with six home runs, 18 RBIs and 18 runs scored in May. However, the 36-year-old first baseman is 4-for-20 (.200) with one RBI against Shields in his career.
During the White Sox six-game winning streak, outfielder Dayan Viciedo is 10-for-25 (.400) with a double, three home runs and 10 RBIs.
With John Danks on the 15-day disabled list due to left shoulder soreness, manager Robin Ventura said Jose Quintana will make his secon start of the season in Wednesday's series finale against the Rays. He's 1-0 with a 1.54 ERA.
Rays: Matsui expected to return to Majors
Hideki Matsui, who signed a Minor League contract with the Rays, is expected to be called up to the Major Leagues for Tuesday's game.
Matsui played in 13 games with Triple-A Durham, hitting .170 with two doubles. He played 141 games with Oakland last season, batting .251 with 12 home runs.
After missing 41 games, catcher Jose Lobaton was activated from the 15-day disabled list on Monday. He went 1-for-2 with a walk and a double. With his return, Chris Gimenez was optioned to Triple-A Durham.
"That's how we had it set up at the beginning of the year," manager Joe Maddon said of the move. "We like Lobaton's abilities and what he can bring, both offensively and defensively."
Evan Longoria (left hamstring), Desmond Jennings (left knee) and Kyle Farnsworth (right elbow) each worked out prior to Monday's game. Both Longoria and Farnsworth still are a ways away from returning, however, Maddon said Jennings is close.
"The drills I saw from a distance, [he] moved easily, running the arcs with [head athletic trainer] Ronnie [Porterfield]," Maddon said. "He wasn't guarding against his stride at all ... D.J. is getting much closer to being able to go out and rehab."
The Rays' last three games have been decided by one run and their record is 1-2.
The teams split the season series 4-4 in 2011 with the White Sox outscoring Tampa Bay, 33-26.
