The White Sox did manage to go 5-4 on their extended road trip to Detroit, Tampa Bay and Baltimore, but they return home tonight against the high-flying Toronto Blue Jays, who lead the AL with 12 wins and have won all five series they?ve played this season, with some questions.

Sox manager Ozzie Guillen is already concerned about Contreras, who is 0-3 while allowing 15 runs (14 earned) on 19 hits and 11 walks over 15? innings.

Colon was brilliant in his first start of the season, pitching 6 shutout innings against the Twins.

The 35-year-old righty took a big step back in his next outing at Tampa Bay, and Colon continued to drop against the Orioles. Colon lasted just 3 innings Thursday, giving up 5 runs on 8 hits and 2 walks.

quot;He wasn?t throwing strikes,quot; Guillen told reporters. quot;His ball wasn?t moving. When he makes the ball move, he?s effective.quot;

Colon was lifted with the Sox trailing 5-0. His pitch count was relatively low (63), but Guillen doesn?t want to mess around with the injury-prone veteran in the third week of the season.

quot;I?m not going to leave Bartolo there when he already has 60 pitches,quot; Guillen said. quot;I have to protect this guy. It?s a long summer, and he just didn?t have it today.quot;

The White Sox ? offense didn?t do much against Baltimore starter Adam Eaton, who was lit up his first 2 starts of the season. Eaton held the Sox to 2 runs on 6 hits over 7? innings, and the right-hander also had 9 strikeouts.

quot;We chased a lot of high pitches,quot; Guillen said. quot;He threw the ball pretty good.quot;

Guillen said much the same about the White Sox ? long trip.

quot;It was a pretty good road trip,quot; he said. quot;Last year, we didn?t play very good at all on the road. We played pretty good, and to compete for the pennant, you have to win games on the road.quot;
